St. Mary Parish, LA

Demographic and economic profile of St. Mary Parish, LA, sourced from the US Census Bureau (American Community Survey) via Data USA.

AI Overview

St. Mary Parish is a small south Louisiana parish of 48,455 residents with an economy that generates a notably high GDP per capita of $60,885 against a median household income of only $52,576, a gap that points to capital-intensive industries—likely oil, gas, and marine sectors common to the region—rather than broad wage distribution. The labor force is constrained, with only 54.7% participation, 13.1% holding a bachelor's degree or higher, and an unemployment rate of 5.4%, while a 22.1% poverty rate underscores income concentration. The parish is affordable—median home values sit at $128,000 and median gross rent at $839/month—but a 6.3% population decline over five years signals ongoing outmigration pressure.
