Understanding the fastest-growing states
Across all 50 states and the District of Columbia, population change spans from +9.8% in Idaho at the top of the list to −1.4% in West Virginia at the bottom. The three at the top are Idaho, Florida, and South Carolina; the three at the bottom are Louisiana, Hawaii, and West Virginia.
Idaho grew fastest between July 2020 and July 2025, adding close to 10% to its population. Florida, South Carolina, Texas, and Utah follow, each up roughly 8% or more. The national population grew about 3% over the same five years. At the other end, seven places lost residents: West Virginia, Hawaii, Louisiana, New York, Illinois, Mississippi, and California.
Population change has three parts: net moves from other states, net moves from abroad, and births minus deaths. The second column shows the first of these, and it explains most of the ranking. Florida and Texas each gained more than 750,000 people from other states, while California lost more than 1.6 million and New York more than a million. Many fast-growing states have more deaths than births, so their growth comes almost entirely from people moving in.
These are Census estimates built from administrative records such as tax returns, Medicare enrollment, and immigration data, and Census revises the whole series with each annual release. They describe where people have moved, not whether a state is a good place to move. Fast growth often comes with rising housing costs, which the home price ranking shows.
