The chart and table show the population size and life expectancy of three countries.Summarize the information by selecting key features and making comparison where is relevant.
The bar chart and the table illustrate variations in the demographic size and life span in 1950, 2000 and projections for 2050 in three countries including China, the United States and Spain.
It is striking to note that China is always the most populous country, with its population accounting for more than 400 million in 1950. After 5 decades, this figure tripled and then is projected to keep rising to almost 1600 million in 2050. Meanwhile, a similar trend could be spotted in American population, quadrupling to nearly 400 million over the centenary. The Spanish remained the least and the most stable at around 80 million.
As reflected from table, Life expectancy in all the countries is on a rise especially in China where it is projected to double from the initial 40.1 to 79 in 2050. Also noticeable is life of the Spanish is mostly the longest one, growing from 69 to 82.8 years old over this period except in 2000 when it was surpassed by that of Americans who lived 79 years old. American people will also enjoy rising longevity, approaching 82 years old.
In summary, the Chinese always tremendously outnumber Americans and the Spanish and life span is predicted to improve and become almost equal in these countries.
