U.S. Population Demographics and Statistics

Population Demographics
Change Location...

The American Community Survey (ACS), conducted by the U.S. Census Bureau, publishes detailed estimates of the population each year. Unlike the Census—which is an exact count of people and households every ten years—ACS statistics are estimated based on a representative survey sample. 

How many people live in the United States?

How many people live in each state?

How is the U.S. population distributed by race? 

This chart shows how each racial group's population has changed from 2010 to 2018. The ACS adheres to definitions of race and ethnicity set forth by the 1997 Office of Management and Budget (OMB) standards. These categories are based on self-identification and are "not an attempt to define race biologically, anthropologically, or genetically," according to the Census Bureau

According to the OMB standards, the category of "Hispanic" maps to the concept of ethnicity, not race, and so is not included in this chart. A person who identifies as Hispanic may be of any race or combination of races.

How does the U.S. population differ by age and sex?

Biologically, humans are slightly more likely to give birth to boys than girls—all other factors being equal, the natural ratio is about 105 boys for every 100 girls. This slight imbalance is apparent in the U.S. population data. At the other end of lifespans, women in the United States are more likely to live longer than men. Note: to see data from different years, drag the time-slider underneath the chart.
