The line chart depicts the percentage of citizens who aged 65 and over from 1940 to 2040 in three different countries, namely-the USA, Japan, Sweden. Overall, it is obvious that the proportion of the elderly in the three countries witnesses an ascending trend in the given period.
As is observed, in 1940, the older population in Japan took up 5 % while that of the USA was the highest, 3% as many as that of Japan. Over the next 60 years, there was a gradual decline of 2% in its elderly population before going up to around 5% in 2000. Japan is predicted to become the nation with the largest population of senior citizens among 3 countries with a significant rise of over 15% between 2030 and 2040.
Furthermore, the USA and Sweden rates both grew sharply from 9% and 6% to 15% and 13% respectively in 1980. Subsequently, a leveling out of under 15% was recorded in the elderly people in the USA over the next 40 years before increasing considerably and is expected to reach a peak at around 23% by 2040. Likewise, Sweden dipped slightly and remained between under 15% and 20% during the 40-year period from 1980. By 2040, the elderly is projected to continue to climb and take up approximately 25% of the Swedish population.
