What contributes to population change in Louisiana?
A state’s population is influenced by three factors:
- Natural population change: If births outnumber deaths in a given year, natural population growth is positive. If deaths exceed births, it is negative. Between 2024 to 2025 natural population change was positive in Louisiana, with births exceeding deaths by 2,800.
- Immigration: international migration directly into or out of a state. If more people move in than move out, population change from immigration is positive. If more people move out than move in, it’s negative. Louisiana’s population change from immigration was positive, with about 14,900 more people coming from another country to Louisiana than leaving.
- Domestic migration, moving between states: Louisiana’s population change from domestic migration was negative, with about 14,400 more people leaving for another state than moving in.
Between 2024 and 2025, immigration was the primary driver of population growth in Louisiana.
