Percent change runs from the April 1, 2020 estimates base to July 1, 2025. People per square mile is the July 2025 estimate divided by the parish's land area in the Census Bureau's 2020 Gazetteer file, so lakes and bays are left out.
How Louisiana's population is spread out
Grouping the parishes by size shows how concentrated the state is:
| Residents (July 2025) | Parishes | Total residents | Share of state |
|---|---|---|---|
| 250,000 to 999,999 | 5 | 1,786,789 | 39% |
| 100,000 to 249,999 | 9 | 1,384,628 | 30% |
| 25,000 to 99,999 | 22 | 1,024,786 | 22% |
| 10,000 to 24,999 | 20 | 364,076 | 8% |
| Under 10,000 | 8 | 57,910 | 1% |
5 parishes with at least 250,000 residents hold 39% of the state's population.

About these numbers
- They are estimates. Between censuses the Census Bureau's Population Estimates Program updates county totals each year from births, deaths and migration records. The next full count is the 2030 census.
- The base is April 1, 2020. The estimates start from an April 1, 2020 "estimates base" built from the 2020 census, which is why it is slightly different from the published census count.
- Each new release revises the past. A newer vintage can change earlier years as well, so compare numbers from the same release, as this page does.
- Statewide total. The parishes add up exactly to the statewide figure of 4,618,189 in the same file.
Using population numbers in a land search
- Big parishes, busy offices. In the most populous parishes, parcel maps and deed records are usually online and searchable, but recording and permit offices are busier. Allow for that if you are on a deadline.
- Small parishes, fewer sales. In parishes with only a few thousand people, land changes hands less often, so there are fewer recent sales to compare a price with. Recorded deeds and the local assessor's sales records are the best source.
- Density hints at lot size. A low people-per-square-mile figure usually means farms, ranches and timber tracts; a high one means subdivided lots. The parcel viewer shows the actual parcel lines.
- Check the official map. Use the parcel viewer link in the table for boundaries, parcel numbers and owner names, then confirm anything important with the local assessor and the office that records deeds.
