How the analysis works
Input
Voting age population from census data
- Census blocks are assigned to polling locations.
- We measure access for potential registered voters as well as currently eligible voters.
Process
Practical constraints
- Avoid sending too many people to any given location.
- Control the number of polling locations changed.
Equity-aware optimization
- Penalize outliers as well as high average values.
- Five people traveling 1 mile is preferred to four people traveling 0.5 mile and one person traveling 3 miles, even though both have the same mean.
Output
Legally permissible locations and access insights
- Addresses for a configuration of polling locations.
- Insight into how different demographic groups experience access.
