Process Step 1
Process description:
Starting with the data from CD113, the lists of Congressional representatives and senators were updated using the Freshman114, House, and Senate data sources. There are no Congressional District boundary changes between the 113th and 114th Congress. In CD113, the Hawaii second district was mapped as multiple features. Those features were merged into a single multi-part feature. The map layer was saved in shapefile and in file geodatabase formats.
