The average life expectancy in America is 20 19.

According to the latest statistical report released by the Census Bureau, the American population is seriously aging. In another 40 years, in 2060, almost a quarter of American residents will be over 65 years old, and the average life expectancy will reach a record high of 85 years.

The report also pointed out that in the next 40 years, the population of the United States will increase by nearly 25%, from the current 332 million to 440 million; By 2028, the proportion of foreign-born population will reach 14.9%, the highest level since 1850.

According to the report, the number of population growth mainly depends on the immigration policy. With the sharp increase in the number of immigrants (defined as a 50% increase in the number of immigrants in the past decade), the population of the United States may increase to 447 million by 2060. But without immigrants, after 2035, the population of the United States will be reduced to only 320 million by 2060.

The Census Bureau's report entitled "20 17 National Population Forecast" also pointed out that the growth rate of American life expectancy in the next 40 years will be slower than that in the previous 40 years.

From 1970 to 20 15, the average life expectancy of Americans has increased by nearly 8 years, but from 20 17 to 2060, it is estimated that it will only increase by 6 years. The reason for this phenomenon is that in the second half of the 20th century, the number of people who died of infectious diseases and cardiovascular diseases decreased. Vaccination, promoting exercise and banning smoking also make people healthier, so life expectancy is naturally prolonged.

However, in the future, due to harmful behaviors such as smoking, obesity and opium abuse, the health of the whole population will be hindered, so the average life expectancy will slow down.

The report pointed out that although the average life expectancy of women will be longer than that of men by 2060, the life expectancy of men will increase by an older age than that of women; Life expectancy of all races will increase, but the biggest increase will be African Americans, American Indians and Alaska Native Americans.

William Frey, a demographer at the Brookings Institution, said that according to current predictions, by 2045, whites will account for less than half of the American population; If there is a large increase in immigration, this will only happen in 2040. If immigration is stopped, by 2060, whites will still be in the majority, about 5 1. 1%.

According to the number of immigrants from 20 1 1 to 20 15, the Census Bureau explores various possible changes between the number of immigrants and the total population. For example, what is the difference between the current situation and if the number of immigrants increases by 50%? What will be the impact of a 50% reduction in immigration? What about zero immigration?

According to the analysis of the Census Bureau, from 2020 to 2060, the above situation will affect the total population as much as 65.438+0.27 billion people.

Frey said, "Compared with other developed countries, our (economic) growth rate is very good, mainly because we have a strong immigration policy in the past 30 to 40 years."
