2020 New Hampshire Congressional Districts

Redistricting requirements

In New Hampshire, districts must:

be contiguous
have equal populations

Interpretation of requirements

We enforce a maximum population deviation of 0.5%.

Data Sources

Data for New Hampshire comes from the ALARM Project's 2020 Redistricting Data Files.

Pre-processing Notes

Precincts are merged by minor civil division, as the enacted has 0 minor civil division splits.

Simulation Notes

We sample 5,000 districting plans for New Hampshire. We use a standard county algorithmic constraint.

Additional Notes:

Uses a county split constraint. Should we drop that? In New England styler, NH does not have congressional redistricting requirements.
Proposed Republican appears likely to be the plan, so first review should look at that. Will need final plan before we are done.

can we try a New England Town or NECTA constraint? see if we can get muni splits to be even more 0, & stop worrying about counties?

The Republican proposed has become the enacted. Data is updated as such. See below for a new validation using MCDs. Do we need to rejection sample to 5000?
