Three new metrics arrive with the Q4 2026 release — each pulled from public records, sample-size gated, and cited to the primary source.
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.
Every metric in this issue — and every metric coming next quarter — traces back to a primary public source. Nothing paraphrased, nothing modeled without disclosure.
One email when a new PERCH Index metric goes live. Build Costs, Permit Timelines, and Market Activity arrive with the Q4 2026 release. No filler between now and then.
