The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 1

The provided line graph illustrates the proportion of senior citizens between 1940 and 2040 in Japan, Sweden, and the USA.

It is noticeable that the percentage of the elderly in the three countries rises significantly over the given period. Also, Japan is predicted to be the country with highest proportion of people aged 65 and over while the opposite is true for the USA in 2040.

In 1940, approximately 9% of American population was 65 years old or over whereas the figures for old people in Sweden and Japan were 7% and 5%, respectively. Over the next 60 years, the percentages of the elderly in Sweden and the USA increased gradually and stood at around 15% in 2000. Meanwhile, Japan experienced a decline in its elderly population to 3% in 1980 before the figure went up gradually to almost 5% in 2000.

The proportion of elderly people in Japan is expected to grow significantly to almost 20% in 2040, making it the nation with largest population of senior citizens. The figure for the USA is forecast to climb continuously to 23% in 2040 and about a quarter of Swedish population is anticipated to be 65 or over at the end of the period given.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 2

The line graph illustrates the proportion of the population aged 65 and above in three different countries (USA, Sweden, and Japan) between a century (1940-2040). At first glance, it can clearly be seen that the proportion of all populations in all countries as mentioned above rose significantly over the period.

At the beginning, people aged 65 and over accounted for approximately 9% among the whole population in USA. That was slightly above Sweden which stood at around 7% at 1940. The percentage of aged 65 and over in USA and Sweden rose gradually with a similar pattern from 1940 to 2020, specifically, in the end of 1990s, the figure of Sweden took over the USA at around 15%. This trend remained continued over the period and in the end of the period (1940) the proportion of population aged 65 and over in USA and Sweden predicted to achieved 22,5% and 25% respectively.

Different with USA and Sweden, Japan started the figured at the lowest level at 5 % in 1940. Furthermore, unlike the 2 countries before, the proportion of old people in Japan then declined until around 1985 before it gradually rose between 1985 to 2030. From 2030 to 2040, the proportion of people aged 65 and more is forecasted to increase dramatically from 10% to around 27,5% at the end of the period which it will be the highest figure among all countries measured.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 3

The line graph compares the percentage of people aged 65 or more in three countries over a period of 100 years.

It is clear that the proportion of elderly people increased in each country between 1940 and 2040. Japan is expected to see the most dramatic changes in its elderly population.

In 1940, around 9% of Americans were aged 65 or over, compared to about 7% of Swedish people and 5% of Japanese people. The proportions of elderly people in the USA and Sweden rose gradually over the next 50 years, reaching just under 15% in 1990. By contrast, the figures for Japan remained below 5% until the early 2000s.

Looking into the future, a sudden increase in the percentage of elderly people is predicted for Japan, with a jump of over 15% in just 10 years from 2030 to 2040. By 2040, it is thought that around 27% of the Japanese population will be 65 years old or more, while the figures for Sweden and the USA will be slightly lower, at about 25% and 23% respectively.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 4

The line graph shows the percentages of people aged 65 and above in three countries since 1940, with projections until 2040.

Overall, while the proportions of over-65s in the US and Sweden have increased moderately, the proportion in Japan has remained essentially unchanged. However, figures in three countries are all expected to go up significantly.

The US had the oldest population in 1940, with nearly a tenth of its population aged 65 and over. This number then climbed to 15% in 1980 before staying at a plateau of roughly 14%. The plateau is forecast to last until 2018, after which there will be a sharp growth to about 23% in 2040.

In 1940, approximately 7% of Sweden's population was 65 years and older. The percentage kept increasing, overtaking the figure in the US in around 1998. Growth is expected to continue and reach 25% by 2040.

Hovering between 3% and 5%, Japan has had a lower percentage of over-65s than the other two countries. However, the proportion is predicted to double to 10% by 2030 and soar to 27% by 2040, the highest of the three countries.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 5

The line graph presents us with the percentage ratio of people aged 65 years or older to the number of the gross population between 1940 and 2040 for Japan, Sweden and USA.

Overall, throughout the entire period, USA and Sweden had an upward trend of the percentage share of 65 and above age group people. However, the elderly group’s share initially experienced a steady decline in Japan, but it is expected to rise exponentially and eventually overtake that of the other two countries by the end of the given period.

In 1940, percentage share of 65 and above age group people to the entire population of USA and Sweden were about 9 and 7 percent, respectively, and these ratios kept rising along the period 1960-1980. Afterwards, experiencing a slight decline for around 12 years, Sweden’s rate of elderly population started climbing till 2014, while that of USA remained stagnant along the same period. However, from 2026 onwards, both countries are expected to experience a rising trend of their 65 and above aged population growth compared to the rest.

On the other hand, in 1940, Japan’s aged people contained only 5 percent of its entire population, which was the lowest among the stated three countries. Furthermore, this percentage share continued declining until 1960 and remained stable in the next 28 years. However, from 1988 onwards, the ratio of Japan’s aged group to the total population of the country has been going through a smooth rise which is expected to continue till 2030. Most importantly, approximately from 2030 to 2035, Japan is expected to see a vertical rise of the share of elderly population in its society, and it might be followed by a moderate increasing trend from 2035 onwards.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 6

The line graph presents a comparative analysis of the proportion of the population aged 65 and over from 1940 through to a forecast for 2040 across three countries: Sweden, the USA, and Japan.

The overview of the graph reveals a notable trend where each country experienced an increase in the proportion of their elderly population over the 100-year period, with particularly stark growth projected for Japan. While the USA and Sweden showed a gradual rise, Japan's figures were initially the lowest but are predicted to surpass the other two countries by 2040.

Delving into specifics, in 1940, between 5 to 10 percent of the population in the USA and Sweden were aged 65 and above, compared to Japan's lower figure of under 5 percent. The subsequent decades saw a steady increase for the USA and Sweden, with both reaching approximately 15 percent by 1980. Conversely, Japan's proportion of the population aged 65 and over decreased slightly during the same period.

However, the turn of the millennium marked a dramatic shift for Japan, with a sharp escalation that suggests a surging trend leading up to 2040, where it is anticipated to exceed 25 percent, overshadowing the projections for both the USA and Sweden. By contrast, the USA and Sweden are expected to experience a more moderate ascent in the proportion of their elderly populations, though both will also see an increase beyond their current statistics. This data implies significant demographic shifts and potentially reflects the advancements in healthcare and longevity in these nations.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 7

The line graph presents a comparison of the percentage of individuals aged 65 and above within the populaces of the USA, Sweden, and Japan, spanning a century from 1940 to 2040.

The most striking observation from the graph is the overall upward trajectory in the proportion of the population aged 65 and over across all three nations, with notable fluctuations and a particularly steep incline predicted for Japan in the latter decades. While the USA and Sweden display a progressive increase over the years, Japan's figure initially descends before ascending sharply post-1990.

In the initial year of 1940, the USA led with just under 10% of its population being elderly, overshadowed slightly by Sweden at around 7%, and Japan commenced with the smallest elderly population at 5%. From there, the USA and Sweden experienced growths in their elderly proportions, with the USA's percentage gently ebbing post-1980 before resuming its rise, and Sweden's proportion displaying intermittent declines between the 1980s to 2020s.

Japan's proportion of the population aged 65 and over, conversely, underwent a decrease until 1990, after which a remarkable surge is forecasted, overtaking both the USA and Sweden by 2040. This amplification is anticipated to continue unabated, culminating in Japan housing the largest percentage of the elderly, whereas the USA is projected to have the smallest by 2040. This trend underscores significant demographic shifts, particularly in Japan, suggesting profound societal and economic implications for the future.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 8

The line chart elucidates the trends in the proportion of the population aged 65 and above across a span of a hundred years, from 1940 to a projected point in 2040, for the United States, Sweden, and Japan.

In a broad overview, it's evident that all three nations have experienced an upward trajectory in their elderly demographics, with Japan's growth appearing particularly steep towards the latter years. The United States and Sweden show a more gradual yet consistent increase, converging on a similar figure by 2040.

Delving into specifics, the United States began the period with the largest proportion of the population aged 65 and over, starting just below 10%. This figure ascended steadily over the next 60 years, hitting the 15% mark as the millennium turned. Projections suggest a continuation of this pattern, with expectations set for the proportion to surge to approximately 25% by 2040. Similarly, Sweden's trajectory mirrors this progression but commenced from a slightly lower baseline of about 7%. Its anticipated growth runs parallel to the U.S., also reaching near 25% by 2040.

Japan presents a contrasting narrative. The proportion of the population aged 65 and over remained the lowest among the trio for the initial 65 years, hovering beneath 5%. Post-2005, the growth accelerated at an unprecedented pace, surpassing both the U.S. and Sweden. By 2040, it is projected that nearly 30% of Japan's population will be elderly, marking the highest proportion among the compared countries. This substantial rise underscores a significant demographic shift, indicating that by 2040, the proportion of the population aged 65 and over will constitute a substantial segment, with nearly one in four individuals in these nations falling into this age bracket.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 9

The line graph presents a comparative analysis of the proportion of the population aged 65 and over in Japan, Sweden, and the United States from 1940 projected through to 2040.

An overarching trend evident from the graph is the universally escalating proportion of the population aged 65 and over across all three nations, with Japan expected to undergo a remarkable surge post-2030, overtaking both Sweden and the United States by 2040. Notably, while the trajectory of Sweden and the United States demonstrates a steady climb throughout the century, Japan's growth curve is characterized by a delayed yet steeper ascent.

From 1940 to the close of the 20th century, Japan maintained a relatively low percentage of older adults, consistently staying under 5%. In contrast, Sweden and the United States exhibited a moderate rise, surpassing the 10% mark by the 1980s. The 1990s mark a period of slight decline for Sweden and the United States, a prelude to the pronounced growth that followed. By 2010, Sweden's proportion of the population aged 65 and over escalated to 20%, with the United States holding at 15% and Japan beginning to accelerate, reaching 7%.

Forecasting ahead to 2040, projections suggest a dramatic augmentation in the proportion of the population aged 65 and over, with Japan's percentage expected to more than double, exceeding 25%. This anticipated growth positions Japan at the pinnacle of the comparison, with Sweden mirroring this figure and the United States following closely at 23%.

The line graph provides a comparative analysis of the proportion of the population aged 65 and over from 1940 through to a projection for 2040 in Japan, Sweden, and the United States.

An overarching trend observed from the graph is the universal upward trajectory in the proportion of the population aged 65 and over across all three nations. Notably, Japan, which commenced as the country with the smallest percentage of elderly in 1940, is projected to surpass the others by 2040, becoming the country with the most substantial elderly population. In contrast, while both Sweden and the USA exhibit a consistent increase, their growth appears more linear and less pronounced than that of Japan.

Delving into specifics, Japan's initial 5% elderly population in 1940 was half that of the USA's 10% at the time. Throughout the mid-20th century, the proportion of the population aged 65 and over in Japan diminished slightly, only to surge upwards from the 1980s onwards. This sharp incline is poised to escalate post-2020, positioning Japan at the forefront with the highest proportion of elderly by 2040. In direct comparison, Sweden and the USA maintained a gradual and steady incline from approximately 6% and 9% respectively in 1940, with projections indicating a rise to nearly one-quarter of their populations by 2040.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 11

The line graph depicts the percentage of senior citizens, who are older than 65 years, over a century in three countries, namely the United States, Sweden and Japan, from 1940 and also gives projection till 2040. A glance at the graph makes it clear that Japan will have more percentage of the aged population in the future despite its fewer percentage of this population in the early 40s and one-fourth of the world population will be older people in 2040.

The illustration shows that the average old population in 1940 was between 5 to 10 percent in all the three countries and the USA had the highest percentage of aged people while it was lowest in Japan. The ageing population in the USA grew steadily and reached up to 15% in the year 2000. It is expected to be doubled and reach nearly 25% in 2040. Similarly, in Sweden, the percentage of aged people grew from about 7% in 1940 to 15% in 2000 and is heading towards 25% in 2040. In contrast, the aged population in Japan remained the lowest, which was less than 5% until 2005 and expected to grow and reach the highest point, about 30 percentage, in 2040. The graph clearly reveals that the ratio of aged population will increase in 2040 and almost one of every four citizens in these three countries would be over 65 years old in 2040.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 12

The given line graph compares the aged people of Sweden, the USA and Japan from 1940 and gives projection till 2040.

As is observed from the line graph, initially in 1940, the proportion of aged people who were over 64 years old was between 5 to 10 percent. This rate kept on increasing in the USA and Sweden while decreased in Japan. After 40 years in 1989, this percentage was around 15% both in Sweden and the USA while it was only 2-3% in Japan. The more the aged people in a country the better the life expectancy and medical improvement and this indicated the improvement in the USA and Sweden while downgrade trend in Japan. But after 2000, the rate of aged people in Japan kept increasing sharply and it is projected that in 2040 the number of aged people would surplus the number in Sweden and the USA though these latter two countries would also have more aged people in these coming years they have now. This also forecasts the life expectancy and medical advancement in Japan after 2030.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 13

The line graph illustrates the percentage of citizens who are aged 65 or above in three various nations from 1940 to 2040.

Overall, it is clearly shown that the proportion of the population who aged 65 or above in the USA and Sweden increases from 1940 to 2040 with slight drops in between whereas that in Japan decreases starting from 1940 to 1980 before a sharp rise in the number of elderly people in that country.

Initially, in 1940, there was a higher percentage of older people living in the USA (just below 10%) than Sweden (around 7%), it was then followed by Japan with only 5%. In the USA, there was an increasing trend in the proportion of elderly people from 1940 to 1980 and decreased slightly. However, it is predicted that the figure for this will eventually rise until 2040. A similar pattern can also be observed for the result obtained in Sweden, the figure for the percentage of older people increases from 1940 to 2040 with two gradual dips from 1980 to 1990 and from 2010 to 2025.

Turning to Japan, it is apparent that there was a slight decline in the proportion of older people from 1940 to 1990 before it showed an upward trend. It is believed that the figure will soar dramatically from 2030 onwards and reached its peak in 2040. Lastly, Japan will become the country with most elderly people among the three nations and USA is the least.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 14

The presented line graph demonstrates proportion of senior citizen in the USA, Japan, and Sweden in a century period between 1940 and 2040. In general, there has been an increase of elder population in all countries observed since 1940 and is predicted to jump up gradually until 2040.

Looking at the detail, in Sweden, the population of seniors had gradually increased since 1940. It was about 7% in 1940 and has been improved gradually year to year.

Furthermore, it is forecasted that the proportion will keep growing and will hit nearly four times higher, about 25%, in 2040. On the other hand, the USA also showed a rise in the proportion of elderly. It was only started at about 9% in 1940 and has been swelled essentially and is predicted to hit 20% in 2014.

Meanwhile, Japan showed an incredible trend of proportion. It was about 5% in 1940 and slowly had declined until around 2005 when it reached almost the same figure as in 1940 and has been dramatically increased and will rise continually to over 5 times higher, around 27%, in 2040.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 15

The provided illustration reveals data about the percentages of people who were elderly in three countries. This research was conducted to looking further information in three different nations; they were Japan, Sweden and USA. All of the samples were aged 65 and over, whereas the data provides a view in the long term which is 100 years.

Firstly, older population in Sweden and USA had a small difference in 1940 because they were both approximately 10% of the total population. These countries had a steady improvement over several years in terms of their number of elderly people. Meanwhile, they are predicted to have a similar result in 2040; their elder generation will rise around 25% in that year.

Secondly, Japan was position as the lowest ranked nation in 1940 which had fewer old people than the other two countries. Over the year, Japan will have the largest proportion of elder people in the future. According to the given figures, Japan will notice an increase in 2020 to 2040 in terms of their elder generation proportion. It will put Japan to have an aged population with more than 25%.

Lastly, all of the nations will have a higher proportion of elderly people in the coming years which indicate the enhanced life expectancy.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 16

The graph compares the growth of population aged 65 and over in Japan, Sweden, and America from 1940 to 2040. According to the graph, it can be clearly seen that although initially Japan’s ageing population ratio was lower than that of Sweden and USA and will remain so till 2030. But it is predicted that elder people’s percentage in Japan will increases significantly afterwards.

Based on the graph, between 1940 and 1980, Japan’s elderly population remained below 5% of total population in contrast to Sweden and USA. Senior citizens in the later two countries grew gradually above 10% respective to the overall population. When Sweden and USA’s elderly population percentages slightly dropped in 1990, Japan started to show an increase in its population aged 65 and over. Further, in 2010, elderly people in Sweden and Japan rose to 20% and 7% respectively while USA’s percentage remained the same i.e. 15% in that period. Despite Sweden’s temporary drop, the population of elders will keep going up dramatically, particularly after 2020 and will peak in 2040. After 2030 Japan’s elderly population percentage will grow more than double to above 25% and that will place Japan in the highest position in terms of senior citizen ratio followed by Sweden (25%) and USA (23%).

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 17

The percentage of elderly people aged 65 and over, from the year 1940 and projection till 2040 in three countries - Japan, Sweden, and United States of America is illustrated in the given diagram.

Based on the chart it can be seen that Japan had the lowest percentage of people who aged 65 and over in the year of 1940. It is surprising that Japan estimates that they will have the highest percentage of these elderly people in 2040.

By looking at the detail, in 1940, Japan had only 5% elderly people compared with the USA, where 10% of total population was over 64 years old. While the proportion of elderly progressively increased in Sweden and the USA, the number of elders in Japan decreased till the end of the 80s. After 1980, the proportion of the elderly population in Japan dramatically increased and it is estimated to extremely raise after 2020. In 2040, Japan will be the land of the highest percentage of elders.

Looking at the elderly people's percentages in two other countries- Sweden and the USA, it can be stated that, the proportion steadily increased and it is predicted that this percentage will keep on increasing. In 1940 the percentages of elderly in Sweden and the USA were about 6% and 9% respectively and it is estimated that these will reach to about one-fourth of the total population.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 18

The graph shows the increase in the ageing population in Japan, Sweden and the USA. It indicates that the percentage of elderly people in all three countries is expected to increase to almost 25% of the respective populations by the year 2040.

In 1940 the proportion of people aged 65 or more stood at only 5% in Japan, approximately 7% in Sweden and 9% in the US. However, while the figures for the Western countries grew to about 15°o in around 199C, the figure for Japan dipped to only 25% for much of this period, before rising to almost 5% again at the present time.

In spite of some fluctuation in the expected percentages, the proportion of older people will probably continue to increase m the next two decades in the three countries. A more dramatic rise is predicted between 2030 and 2040 in Japan, by which time it is thought that the proportion of elderly people will be similar in the three countries.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 19

The line graph illustrates the percentage of senior citizens of Japan, Sweden and USA who are 65 or above from 1940 to 2040.

Overall, it is apparent that the proportion of 65 and over people will rise in all the countries and it is foreseen that Japan will have the maximum percentage of senior citizens by 2040.

In Japan, a slight decrease was seen in proportion of people aged 65 or over in the initial years from 1940 to 1960 before it surged gradually to 10% in 2020. It is predicted that the percentage will witness a steep growth to reach 25% by 2030 followed by a marginal increase to 27% by 2040.

The proportion of people aged 65 and above were higher in USA at 10% than Sweden at around 7%. However, after experiencing some fluctuations Sweden's population surpassed USA in 2000, accounting to 15%. The proportion of people who were 65 and over in Sweden reached a peak of 20% in 2020 and is projected to further soar to 25% by 2040. On the contrary, percentage of USA citizens aged 65, plateaued from 1980 till 2020 at 15% and is speculated to have the least percentage of senior citizens amounting to 23% by 2040.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 20

The line graph compares the percentage of people who are aged 65 and above in Japan, Sweden and the USA over a period of 100 years from 1940.

Overall, there will be a huge number of upwards in the proportion of elderly people in the three countries in the future.

In 1940, the percentage of three countries revealed almost the same results, the USA 9%, Sweden 7% and Japan 5%. In 1980, the number of elderly people in the USA increased gradually to 15% and this figure declined slightly to 14% in 2015. The number of people experienced a peak at 22% until 2040.

In contrast, the percentage of older people in Sweden climbed steadily to 20% in 2020. After 20 years, it will rocket to 25%. In 1960, Japan’s percentage declined minimally to 4% and stabled at this position in 1988. In Japan, the number of aged people saw a significant climb by 23 % over the given period of 52 years from 1980.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 21

The line graph provides information about the percentage of the population that is more than 65-year-old in Japan, Sweden and USA from 1940 to 2040, a period of 101 years. Overall, it can be observed that the levels of ageing population for these three countries are projected to grow, albeit at a different pace, till 2040.

In 1940, percentages of the aged were less than 10% of the population for these three countries. Between 1960 to 1980, the USA and Sweden’s ageing population rose by 5 %, while this figure for Japan dropped slightly to reach around 3%. However, after 1990, Japanese’ ageing population continued to go up. This figure is projected to increase steeply after 2030. By 2040, old people in Japan will have reached more than one-quarter of the total population. In contrast, the number of aged in the USA will remain stable at around 15% until 2020. At the end of the period, the proportion of elderly population in USA and Sweden will show a similar pattern (25%).

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 22

The line chart illustrates the proportion of the population aged 65 and above in three distinct countries from 1940 to 2020, as well as projected projections through 2040.

In 1940, the United States had the greatest percentage of individuals aged 65 and over, followed by Sweden and Japan. The United States had the highest proportion of individuals aged 65 and over, with Japan having the lowest proportion. In 1940, Sweden's percentage was around 7 percent. The proportion of Americans aged 65 and above increased steadily until it reached 10% in 1960, surpassing Sweden by 2 percentage points. In the year 2000, the trend between the United States and Sweden shifted. Sweden's share of the population varied erratically and eventually reached 18 percent, surpassing the United States by three percentage points in 2020. As of 2020, Japan's share of the population aged 65 and above was 7 percent.

In terms of demographic projections for the future, it is projected that the proportion of the population aged 65 and above in Japan will reach 27 percent by 2040, exceeding the proportions in the United States (23%) and Sweden (25%).

To summarize, the proportion of elderly people in the United States of America and Sweden varied significantly over time, while the numbers in Japan rose steadily.

The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 - mẫu 23

The bar chart displays the percentage of those aged 65 and above in the populations of three countries from 1940 with projections to 2040.

Overall, the graph indicates that the older populations of all three countries increased until 2020, and the same trend is predicted for the future years. While in 1940, the USA and Japan had the highest and lowest proportions of elderly citizens, 65+, respectively, they are expected to switch positions by 2040.

Considering the past, the proportion of the elderly in the USA was the highest, at around 9% in 1940, and after that, it grew to 15% after 40 years before remaining relatively stable until 2020. Sweden's value started at around 7%, and despite fluctuations, it increased to a fifth over the next 80 years. However, the proportion of the Japanese who were 65 and over was 5% at the beginning of the period, it then fell to roughly 3% in 1960, and only after 1990 did it rise to roughly 7% by 2020.

Looking at the future, after dipping briefly, Sweden's elderly contingent will reportedly rise to account for a quarter of its population in 2040, and the USA's is forecast to climb to approximately 23%. Meanwhile, in Japan, this contingent is predicted to skyrocket to reach the top, making up about 27% of the total population in 2040.

The graph illustrates the proportion of individuals aged 65 and over in the USA, Sweden, and Japan from 1940 to a projection in 2040. Overall, all three countries display an upward trend in the percentage of their elderly population over the century. Japan’s percentage exhibits a remarkable increase, especially after the year 2000, and it is anticipated to have the highest proportion by 2040, soaring beyond 30%.

In 1940, all three nations started with less than 10% of their population being 65 or older. The USA and Sweden maintained a gradual increase over the decades. By 2040, the USA’s percentage is forecasted to approach 20%. Sweden, after a period of stability in around 1980, observes a steeper rise, aligning closely with the USA’s trajectory.

Japan, however, presents a distinct pattern. From 1940 until about 2000, Japan’s elderly demographic remained below 20%, much lower than the other two countries. But after that, there’s a dramatic surge, and by 2040, over one-third of Japan’s population is projected to be aged 65 or older, significantly surpassing both the USA and Sweden.

The line graph compares the percentage of people aged 65 or more in three different countries over a period of 100 years. It is clear that the elderly population increased in all three countries, but Japan had the most dramatic change.

In 1940, the proportion of people aged 65 or over was below 5% in Japan, slightly higher than that in the USA and Sweden, which were around 4%. The percentages of elderly people in the USA and Sweden rose steadily over the next 60 years, reaching about 15% and 17% respectively in 2000. Japan, however, remained stable until the 1980s, when it started to climb sharply, surpassing the other two countries by 2010.

The trend continued until 2040, when Japan was projected to have nearly 30% of its population aged 65 or over, more than double the percentage in 2000. The USA and Sweden also increased, but at a slower rate, reaching about 23% and 25% respectively.

In summary, the line graph shows that Japan faced a significant challenge of an aging population, while the USA and Sweden also experienced a gradual rise in this demographic group.

The given line graph illustrates the changes in the percentage of population aged 65 and above in the USA, Sweden, and Japan from 1940 to 2040. Overall, it can be seen that all three countries witnessed an upward trend in this age group, with Japan having the most remarkable increase.

In 1940, Japan had the lowest percentage of elderly people, at less than 5%, followed by the USA and Sweden, which had about 4% each. For the next four decades, Japan maintained a low and stable level, while the USA and Sweden had a slight and steady growth, reaching around 9% and 10% respectively in 1980.

From 1980 onwards, Japan experienced a rapid and dramatic rise in its elderly population, surpassing the USA and Sweden by 2010, and reaching almost 30% by 2040. The USA and Sweden also had an increase, but at a more moderate pace, attaining about 23% and 25% respectively in 2040.

To conclude, the line graph reveals that Japan had a major challenge of dealing with an aging population, while the USA and Sweden also saw a moderate growth in this segment of their population.

The line graph illustrates the variations in the percentage of old people aged 65 and above in Japan, Sweden and USA over a 100-year period from 1940 to 2040.

In 1940, just under ten percent of the US population was 65 and over, the highest figure among the listed countries. Sweden and Japan stood at the second and third place respectively with nearly 7% and 5% population in this age range. In the next 50 years (i.e. 1940-1990), the curves followed strikingly similar upward trends in western countries. The proportion of elderly in the USA reached the mark of 15% whereas the percentage was slightly less than 15% in Sweden. In comparison, there was a small decrease of about 2% in the Japanese figures during this period.

Between 1990 and the present, the American figures remained constant while Sweden and Japan experienced a gradual increase in their percentages. Notably, these proportions are expected to rise dramatically in the next two decades in all the three countries. By 2040, the ageing population will account for nearly one fourth of the total population in these nations.

Overall, it is evident that the proportion of elderly people has risen in all the given countries. This trend is predicted to continue in the future and by 2040, these countries will have a similar number of old people (about 25%).

The presented line graph gives information about the percentage of the population that is more than 65-year-old in Japan, Sweden and USA from 1940 to 2040, a period of over 100 years.

Overall, it can be vividly observed that the levels of ageing population for these three nations are foreseen to grow, albeit at a different pace, till 2040.

A glance at the graph reveals that in 1940, the proportion of the golden aged was less than 10% in the three countries. Between 1960 to 1980, the USA and Sweden’s ageing population rose by roughly 5 %, while this figure for Japan went down slightly to reach around 3%. However, after 1990, Japanese’ ageing population continued to go up and it is projected to increase steeply after 2030. In 2040, the greying population in Japan will have reached more than one-quarter of the total population. In contrast, the number of senior citizens in the USA remained stable at around 15% until 2020. At the end of the period, the ratio of elderly population in the USA and Sweden will show a similar pattern and reach at about 25 %.

The given line graph depicts comparable changes in ratio of individuals aged 65 and older in Japan, The USA, Switzerland.

The ratio of senior citizens in the population of USA was about 9% in 1940. The changes in the demographic trends indicate clearly that the ratio of older people in the population is set to rise to about 23% by 2040 even though the population of old people stabilized at 15% in 1980, and in fact is expected to decline marginally till 2020.

Similarly, the ratio of the old people in the Switzerland is also expected register a rise of approximately 19% by 2040 – from about 7% in 1940 to 26% in 2040.

On the other hand, even though the ratio of aged Japanese was lowest in 1940 – 5%, and it further declined to below 5% till 1990, it is expected to rise more than five folds in corresponding period, to more than 27%.

The proportion of old people would rise in all the 3 countries in the quoted 100 period.
