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 2023 to 2024 natural population change was positive in Colorado, with births exceeding deaths by 17,300.
- 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. Colorado’s population change from immigration was positive, with about 33,200 more people coming from another country to Colorado than leaving.
- Domestic migration, moving between states: Colorado’s population change from domestic migration was positive, with about 5,400 more people moving to Colorado from other states than leaving.
