By Victoria Johnson, Chatham News + Registration Staff

Chatham County’s population grew by about 20% from 2010 to 2020, according to data from the 2020 U.S. Census – and just like the majority of the United States, most of that growth comes from Chatham’s minority populations.

The US Census Bureau began publishing detailed population statistics in mid-August; by mid-September, most of this data had become more readily available on the office’s website, Using this data, along with data from previous censuses dating back to 1990, the News + Record has compiled five key points on Chatham County’s demographic trends in 2020:

Chatham is becoming increasingly racially and ethnically diverse.

In 1990, the population of Chatham County was approximately 75.3% White, 22.7% Black, and 1.4% Hispanic (all races). The other races made up less than 1% of the county’s population. The 1990 census did not identify individuals of two or more races.

In 2020, however, Chatham’s population was 69.6% White, 10.2% Black, 13.6% Hispanic (any race), 2.1% Asian, and 3.9% multiracial. Collectively, the other races – Native Americans and Alaskans, Hawaiians and other Pacific Islanders, plus “another race” – make up less than 1% of the county’s population.

Chatham’s white population is not declining, but its share of the county’s population is.

For the first time on record, the non-Hispanic white population of the United States declined in 2020, from 196 million in 2010 to 191 million last year. Its overall share of the U.S. population has also declined, from 63.7% in 2010 to 57.8% in 2020.

In Chatham, however, things look a little different. The county’s non-Hispanic white population has grown by around 17%, although its share of Chatham’s population has grown from 71.2% to 69.6% in the past decade.

Across North Carolina, the non-Hispanic white population grew by about 1.4%. In 2020, about 60% of the state’s population identified as white.

Chatham’s Hispanic population grew by a quarter from 2010 to 2020. It is now the largest minority population in the county.

Chatham County’s Hispanic population grew by about 26% from 2010 to 2020, according to 2020 U.S. Census data, overtaking Chatham’s black population as the county’s largest minority group.

Chatham’s non-Hispanic black population has steadily declined over the past 30 years.

In 1990, the census counted 8,794 non-Hispanic black residents. In 2000, that number fell from a few hundred to 8,355, and then another hundred in 2010 to 8,272.

In 2020, Chatham’s non-Hispanic black population numbered 7,768, a 7% decrease from the overall population from 2010 to 2020. In contrast, North Carolina’s non-Hispanic black population grew by nearly 88,000 people. (4.3%) between 2010 and 2020.

Chatham’s multiracial population experienced the highest growth rate between 2010 and 2020.
