Congressional representation is reapportioned every decade following the completion of the decennial census. Each year the Census Bureau produces the Population and Housing Unit Estimates Program; the most recent estimate was released December 2022.

METHODOLOGY

A weighted average growth rate is applied to the July 1, 2022 estimates of the resident population of the United States from the Census Bureau to produce a forecast for the 2030 apportionment.

Similar to patterns seen during the 2020 apportionment, states in the South and the Mountain West would be expected to continue to grow while California, Great Lakes states & Northeast states would be expected to continue to lose seats.
