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

The PEP estimates base here is 114,887 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.

The April 2020 census count (114,871) and the Vintage 2025 April 2020 base (114,887) differ by 16. The gap comes from boundary changes and the Census Bureau’s revised 2020 base, not population change, so measure growth within one series. Source and download

Growth and density

Between July 1, 2020 and July 1, 2025, North Charleston gained 13,635 residents, a 11.79% increase. The annualized change over these five elapsed years was +2.25%. 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 77.99 square miles of land. Dividing the July 1, 2025 population by that compatible land area gives 1,657.2 people per square mile. Water area is excluded. Density depends on geographic boundaries. It describes this entire place, rather than a typical neighborhood or built-up area.
