The total population of the United States was about 329.48 million people in 2020. It is forecasted to reach 417 million people by the year 2060 according to a population projection from the U.S. Census Bureau. With a population growth rate of 0.47 percent in 2019, the United States was one of the faster growing developed countries in the world. In 2018, the birth rate in the U.S. was about 11.6 births per 1,000 inhabitants while the death rate was 8.68 deaths per 1,000 people in 2018. Life expectancy in the U.S. continues to rise and is now at 78.54 years for Americans born in 2018.
The age structure of the U.S. population in 2019 has remained roughly the same as the last ten years and looks as follows: around 16 percent of the population is 65 and older, 18 percent is younger than 15, and the residual 66 percent is aged between 15 and 64. According to the U.S. Census Bureau, the median age in the United States stood at 38.4 in 2019, which is low compared to most other developed countries, such as Japan, Germany, and France. In developing countries, where life expectancy is lower and death rates are higher, the median age is usually substantially lower.
After several waves of immigration over the centuries, the United States of America is a very diverse multi-ethnic society. A population breakdown by race/ethnicity shows that the majority of Americans are white, but roughly 44 million people are of Black or African American descent, and around 800,000 people living in the U.S. are of native Hawaiian and other Pacific Islander descent. Asians are currently the fastest growing ethnic group in the U.S., growing from 13.48 million people in 2006 up to 19.5 million in 2019.
