Methodology

Every number here has a sample size, a source, and a method.

PERCH Index publishes only what we can defend. Sample-size floors are enforced per state; anything short of the threshold shows as "insufficient data" — never as a filled placeholder.

Sources of record.

Every metric in this issue — and every metric coming next quarter — traces back to a primary public source. Nothing paraphrased, nothing modeled without disclosure.
