elder population statistics

Based on a survey, the graph was divided into 2 parts. Firstly, while the figure of the elderly in Sweden and USA from 1940 to 2016 increased steadily, the population of aged 65 or more in Japan had unpredicted changed. However, from 2020 to 2040, the percentage of the USA and Swedish people is expected to go up dramatically while Japanese people leaps enormously.

In 1940, around 9 % the USA elderly aged 65 and over, while in Japan and Sweden about 5 % and 7%. In 1990, the proportion of the old in Sweden overtook the USA. By contrast, the percentage in Japan decreased seriously about 4%. In 2030, some people expect that the percentage of Japanese population aged 65 and over will go up hugely with rapid speed.

In 2040, it is thought that around 26% of the Japanese population will be 65 years old or more while the percentage of Sweden and USA will be slightly lower. The graph showed us seriously the number of old people, which is increasing gradually. It can have a bad impact on world' economy because of the lack of young employees.

To, you need to provide the graph so that I can confirm the accuracy of the information you are providing. Read the first paragraph and you will see that you are short of the standard paragraph requirement. That simply means that your overview summary is lacking but I am unable to detect the missing information due to the lack of the graph. Watch out for your typing errors. Do not be careless. Remember that all proper nouns are capitalized so you cannot have Japan spelled with a small j as you do now. While the rest of the paragraphs seem to be well informed, I am unsure as to the quality of information provided. Please provide the prompt as soon as you can so that I can compare the data with the graph. You know the rules, we can't help you if we can't see the information.
