Annual population change

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 Oklahoma, with births exceeding deaths by 2,600.
  • 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. Oklahoma’s population change from immigration was positive, with about 8,400 more people coming from another country to Oklahoma than leaving.
  • Domestic migration, moving between states: Oklahoma’s population change from domestic migration was positive, with about 14,500 more people moving to Oklahoma from other states than leaving.

Between 2024 and 2025, domestic migration was the primary driver of population growth in Oklahoma.
