The Pearl River County Mississippi map links the northern county seat at Poplarville with Picayune in the south along I-59 and US 11, while McNeill and Carriere fill the central corridor. The Pearl River, Louisiana boundary, and broad Piney Woods frame growth tied to Gulf Coast and New Orleans access.

The decennial count and July 2025 estimate use different reference dates. Land and water measurements come from the 2025 Gazetteer. The density of 69.2 residents per square mile divides the 2020 population by 2025 land area and does not imply an even distribution among cities, farms, forest, or wetland.
Reading the Pearl River County Mississippi map
I-59 and US 11 connect Poplarville with McNeill, Carriere, Picayune, and the Louisiana approach. MS 26 supplies an east-west route from Poplarville toward Stone County, and MS 43 serves inland travel near Picayune. Subdivision streets and forest tracks are simplified on the county reference map.
Boundary, Water, and Terrain
The Pearl River forms important portions of the western boundary opposite Washington and St. Tammany parishes. To the east, land continues into the Gulf Coastal Plain of Stone and Harrison counties. Pine-covered hills are more pronounced in the north, while lower and wetter stream terrain increases southward across more than 800 land square miles.
Settlement and Regional Context
Poplarville is the administrative center and home of Pearl River Community College. Picayune is the larger southern commercial and residential center, and Carriere and McNeill identify the growing corridor between them. The 2025 estimate is about 5.7 percent above the 2020 count, a notable increase for southern Mississippi.
Practical Map Uses
- Compare Poplarville and Picayune along I-59
- Relate the Pearl River to the Louisiana boundary
- Use McNeill and Carriere to explain the central growth corridor
Frequently Asked Questions
Does the Pearl River form the entire western boundary?
The river system provides an important Louisiana boundary reference, but the full line is not simply one uninterrupted main channel. Tributaries and surveyed boundaries also matter.
How can Pearl River clarify the part of Pearl River County facing Lamar?
Looking only at Poplarville would reduce the map to town labels, whereas Pearl River explains the landscape transition toward Lamar.
