What is a U.S. House district?

Congressional districts are the geographic units that elect members of the U.S. House of Representatives. District MO-3 is one of Missouri's seats in the House; boundaries are redrawn after each decennial Census.

District lines are not the same as ZIP codes, cities, counties, area codes, or TV markets. A single ZIP can touch more than one district at the edges, and US5 maps each published ZIP to a primary district code for browseability.

How to use this MO-3 page

US5 joins published ZIP profiles to congressional district codes so you can scan the district as a list of postal codes with population, income, and housing — then open any ZIP for maps, schools, commute, and climate context.

This is a place-based research view, not a voter roll, campaign tool, or live election results feed. Counts can change when geography publishes update.
