2010 New Hampshire Congressional Districts

[taransamarth]

Redistricting requirements

In New Hampshire, districts must:

1. be contiguous
2. have equal populations

Algorithmic Constraints

We enforce a maximum population deviation of 0.5%.

Data Sources

Data for New Hampshire comes from the ALARM Project's 2010 Redistricting Data Files.

Pre-processing Notes

Since the enacted plan has no minor civil division (MCD) splits, we merge precincts into MCDs prior to simulating districts.

Simulation Notes

We sample 5,000 districting plans for New Hampshire in 2 independent runs of the sequential Monte Carlo algorithm. No special techniques were needed to produce the sample.

Validation

SMC: 10,000 sampled plans of 2 districts on 327 units
`adapt_k_thresh`=0.985 • `seq_alpha`=0.5
`est_label_mult`=1 • `pop_temper`=0

Plan diversity 80% range: 0.077 to 0.688
