2020 Census data: America is more diverse and more multiracial than ever
“Our analysis of the 2020 census results shows that the U.S. population is significantly more multiracial and more racially and ethnically diverse than what we have measured in the past,” said Nicholas Jones, director and senior research adviser. and raising awareness about race and ethnicity in the population division of the US Census Bureau.
People of color made up 43% of the total US population in 2020, up from 34% in 2010.
The share of non-Hispanic whites in the U.S. population fell to 57% in 2020, down six percentage points since 2010, the biggest drop of any race or ethnicity. The share of those who identified as Hispanic or Latino or as multiracial increased the most.
The United States has generally aged since 2010 and the under-18 population has become more diverse.
The adult population in the United States has grown from 237 million to 261 million over the past 10 years. The share of the adult population increased slightly from 76% in 2010 to 78% in 2020.
While the under-18 population has shrunk over the past decade, it is rapidly diversifying. Non-white U.S. residents under 18 now make up 53% of the underage population, up from 47% in 2010.
Non-Hispanic white Americans continue to be the most common group in all states except California, Hawaii and New Mexico, as well as the District of Columbia and Puerto Rico.
There are now seven states and territories — California, New Mexico, Nevada, Texas, Maryland, Hawaii, and Puerto Rico — where the share of non-Hispanic whites in the population is below 50%.
In California, the Hispanic or Latino population officially became the largest racial or ethnic group in the state for the first time. The Hispanic or Latino community now makes up 39.4% of Californians, up from 37.6% in 2010. The non-Hispanic white population in California was 34.7% in 2020.
The census revamped its survey for 2020 to ask US residents more detailed questions about how they identify their race and ethnicity. The Census Bureau said these and other technical changes “enable a more complete and accurate description of how people identify themselves.”
The Census Bureau said comparisons on race and ethnicity between 2010 and 2020 should be “made with caution”, although they are “confident that the changes we are seeing from 2010 to 2020 in measures of diversity …likely reflect actual demographic changes in the population over the past 10 years, as well as improvements in question design, data processing and coding.
Almost all of the country’s population growth has occurred in its cities. More than half of all counties have seen population declines since 2010. The largest increase in county population has been in McKenzie County, ND, which has grown more than 130% since 2010.
“Population growth in that decade was almost entirely in metropolitan areas,” said Marc Perry, senior demographer at the Census Bureau. “Texas is a good example of this, where parts of the Houston, San Antonio, Austin, Dallas Fort Worth, Midland and Odessa metro areas have seen population growth, while many other counties in the state have seen declines. demographic.”
Cities have grown faster than the nation as a whole. The population of metropolitan areas has increased by 8.7% since 2010. The population of the United States has increased from approximately 308.7 million in 2010 to 331.4 million, an increase of 7.35%. This is the slowest population growth since 1930-1940 – the decade of the Great Depression.
