Collin County's rapid growth has resulted in a population that is both older and more racially and ethnically diverse than it was a decade ago, according to the latest estimates from the U.S. Census Bureau.

As more people moved to the county over the last decade, the share of the county's population that is 65 or older grew from 7.8% in 2010 to 11.3% in 2019. Collin County's majority ethnic group—non-Hispanic whites—grew in number, but declined as a share of the population, falling from 63% to 55% of residents during the same span of time.


The county's increase in diversity was driven largely by growth in the Asian American and African American populations. Asian Americans now make up 16.3% of the county's residents, up from 11.5% in 2010. The county's Black population is now 10.9% of the total, up from 8.8% a decade earlier.

Residents of Hispanic ethnicity saw a smaller increase from 14.7% in 2010 to 15.5% of Collin County's population in 2019.
