What contributes to population change in Wisconsin?
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 Wisconsin, with births exceeding deaths by 1,200.
- 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. Wisconsin’s population change from immigration was positive, with about 7,300 more people coming from another country to Wisconsin than leaving.
- Domestic migration, moving between states: Wisconsin’s population change from domestic migration was positive, with about 7,000 more people moving to Wisconsin from other states than leaving.
Between 2024 and 2025, immigration was the primary driver of population growth in Wisconsin.
