## Processing Steps
Precincts for certain counties were not included in the shapefile provided by the Demographer's Office and were digitized from maps provided by the county. Those counties are: Boulder, Denver, Douglas, and El Paso. For Las Animas county, the voter file was geocoded and used to identify precinct boundaries. Demographic data were aggregated from the census block level and precincts were assigned to districts using MGGG's proration software.
