This bill would change how the House of Representatives and electoral votes are apportioned among states by excluding non-citizens from the population count used in that calculation. Currently, House seats and electoral votes are based on total population regardless of citizenship status, but this legislation would count only U.S. citizens for those purposes. The bill would take effect starting with the 2030 census and apply to all future censuses. This would potentially shift representation away from states with larger non-citizen populations toward states with higher citizen populations. The change would affect which states gain or lose congressional seats and electoral votes in presidential elections based on the adjusted population counts.
