Why is the April 2020 estimates base different from a census count?

The PEP estimates base here is 227,944 residents on April 1, 2020. It incorporates the Census Bureau’s corrections and geographic revisions and serves as the starting point for this annual series. It is not labeled an original 2020 census count. The chart starts at July 1, 2020, so its five-year change uses two July observations. Read about measurement types.

Growth and density

Between July 1, 2020 and July 1, 2025, Gaston County gained 17,918 residents, a 7.84% increase. The annualized change over these five elapsed years was +1.52%. Annualized change is a summary of the interval; it does not imply that the population changed at that rate in every year.

The 2025 Gazetteer reports 355.75 square miles of land. Dividing the July 1, 2025 population by that compatible land area gives 693.1 people per square mile. Water area is excluded. Density depends on geographic boundaries. It describes this entire geography, rather than a typical neighborhood or built-up area.

Calculations use unrounded source values. Population counts are displayed as integers, percentages to two decimals and density to one decimal. Calculation methods · Growth calculator
