Mississippi County Area & Size Rankings

Understanding Mississippi’s county areas

The land-area range runs from Alcorn County at 400 mi² to Yazoo County at 922.3 mi². The largest has 2.3 times the land area of the smallest and accounts for 2% of the combined county land in Mississippi. Compare with every state’s largest county.

The median county-equivalent land area is 567 mi², below the national median of 604.5 mi². The median describes the middle of the county size distribution; it does not describe how people or development are distributed. A state with a few very large counties can have a much smaller median than its largest entry suggests.

Where water changes the picture

Harrison County has the most assigned water area, at 411 mi². It also has the highest water share, with water making up 41.7% of its total area. Water area and water percentage answer different questions: the first measures an amount, while the second measures the mix of land and water.

Across all 82 entries, water accounts for 3.1% of the combined total area. This is calculated from the summed land and water measurements, rather than averaging county percentages, which would give each small and large county equal weight.

Where people live

An estimated 2,954,160 people lived in Mississippi on July 1, 2025 (−0.2% since 2020), or 0.9% of the national total in this dataset. Harrison County is the most populous county equivalent, with 217,136 residents — 7.4% of the state. The largest by land, Yazoo County, has 22,947.

Across the state there are 63 people per square mile of land. County densities range from 415 in DeSoto County to 3.1 in Issaquena County; the median county equivalent has 43. Switch the map above to density to see where the state’s population concentrates.

Compare the largest and smallest county equivalents in Mississippi to see land, water, and total area on the same scale.

These calculations use the 2026 Census county records listed below. County-equivalent boundaries vary between states; area alone does not measure population, density, or usable land. See coverage and calculation rules.
