Population Growth

The components of population change offer insight into the causes of population growth or decline and help highlight important areas of inquiry. According to the 2020 Census population counts, the Lowcountry region had a population of 273,073. With a land area of 2,848 square miles, the average population density in the region is approximately 96 people per square mile. Between 2010 and 2022, the population in Beaufort and Jasper Counties has continued to grow. The population growth reversed in Colleton and Hampton Counties.

Note: While the 2000, 2010, and 2020 data are based on decennial census, the 2022 data is based on 5-year estimates (2018-2022). Users should exercise caution when comparing this data.
