Census.gov: “The nation as a whole continues to grow older with the median age increasing to 38.2 years in 2018, up from 37.2 years in 2010. The pace of this aging is different across race and ethnicity groups, according to new 2018 Population Estimates by demographic characteristics for the nation, states and counties, released today by the U.S. Census Bureau. From 2010 to 2018, the U.S. population’s median age increased by 1.0 years. Amongst the different race groups:
- The white alone-or-in-combination population increased by 1.0 years.
- The black or African American alone-or-in-combination population grew by 1.4 years.
- The American Indian and Alaska Native alone-or-in-combination population increased by 2.2 years.
- The Asian alone-or-in-combination population increased by 1.7 years.
- The Native Hawaiian and Other Pacific Islander alone-or-in-combination population increased by 2.6 years.
- The Hispanic (any race) population experienced an increase in median age of 2.2 years.
“The nation is aging — more than 4 out of every 5 counties were older in 2018 than in 2010. This aging is driven in large part by baby boomers crossing over the 65-year-old mark. Now, half of the U.S. population is over the age of 38.2,” said Luke Rogers, the Chief of the Population Estimates Branch at the Census Bureau. “Along with this general aging trend, we also see variation among race and ethnicity groups both in growth patterns and aging.” Rogers also noted that alone-or-in-combination groups overlap and individuals who identify as being two or more races are included in more than one of these race groups…”
