pandas-redistrict 0.0.1

# pandas-redistrict

Uses data on redistricting to apply redistricting to older datasets to represent the districts in their current state.

Supports merging and splitting of districts:
- Merged districts are summed up under new identifier
- Split districts are distributed by population-based ratio.

Data on redistricting is in `data/` directory. Currently only available for German *Kreise* (containing reforms in NRW, Sachsen, Sachsen-Anhalt and Mecklenburg-Vorpommern).
