States & metros

Seattle–Tacoma–Bellevue, WA

Building permits (units authorized), 1990–2024, built from county permit files aggregated to today's metro definitions (2023 OMB delineations, held constant) so the geography never shifts under the series (county-code changes are crosswalked; Connecticut's five metros are excluded because its county geography changed incompatibly in 2022). Rank is by units permitted, among the 382 metro areas of the 50 states and DC.
