Caveats

  • Totals for 2010-2019 are Vintage 2019 estimates and 2020-2025 are Vintage 2025; the two series are not reconciled, so a change at the seam includes the vintage revision.
  • City (incorporated place) totals cover 2020-2025 only; no 2010-2019 city series is included.
  • Components of change are published for the nation, states and Idaho's 44 counties; other states' county components are not included.
  • The ten places are Boise City, Meridian, Nampa, Caldwell, Idaho Falls, Pocatello, Coeur d'Alene, Twin Falls, Post Falls and Rexburg, the ten largest by 2025 population estimate.
  • Group quarters estimates, the residual component, population-based rates, and Puerto Rico are not included.
  • The national domestic migration cell is 0 by construction (moves between states net to nothing) and is not stored as an observation; the United States has international migration and natural change only.
