Connect legislative districts to ZIPs, counties, cities, demographics, business activity, health, education, and infrastructure conditions.
Start with the district boundary.
A city, county, postal ZIP, Census ZCTA, and legislative district are different geography types. A shared number or name is not enough to establish a valid join. Record the district plan, crosswalk method, data vintage, and coverage before comparing places.
District metrics and ZIP/county/city crosswalks have not been imported into this edition. The pages provide official source paths and clearly identify unconnected layers.
