Why is the April 2020 estimates base different from a census count?
The PEP estimates base here is 68,757 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, San Patricio County gained 3,214 residents, a 4.67% increase. The annualized change over these five elapsed years was +0.92%. 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 693.32 square miles of land. Dividing the July 1, 2025 population by that compatible land area gives 103.9 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
Components of population change
The published components cover July 1, 2024 through June 30, 2025. Natural change equals births minus deaths. Net migration is arrivals minus departures; it does not establish why people moved.
| Component | People |
|---|---|
| Births | 872 |
| Deaths | 747 |
| Natural change | +125 |
| Net domestic migration | -49 |
| Net international migration | +434 |
| Residual | +9 |
| Total population change | +519 |
Reconciliation: natural change + net domestic migration + net international migration + residual = +519. Births and deaths are already included in natural change and must not be added again. Source: co-est2025-alldata.csv; Vintage 2025.
