The total population of the United States is projected to be about 323 million people by 2016. It is forecasted to reach 420 million people by the year 2060 according to a population projection from the U.S. Census Bureau. With a population growth rate of 0.78 percent in 2015, the United States was one of the faster growing developed countries in the world. In 2015, the birth rate in the U.S. was about 12.4 births per 1,000 inhabitants while the death rate was 8.1 deaths per 1,000 people in 2014. Life expectancy in the U.S. continues to rise and is now at 78.94 years for Americans born in 2014.
The age structure of the U.S. population in 2015 has remained roughly the same as the last ten years and looks as follows: around 15 percent of the population is 65 and older, 19 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 37.8 in 2015, 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 43 million people of Black or African American descent are counted and more than 0.76 million people living in the U.S. are native Hawaiian and other Pacific Island descent. Asians are currently the fastest growing ethnic group in the U.S., growing from 13.48 million people in 2006 up to 17.98 million in 2015.
