Counts reflect the separate covered-trade snapshot. A “—” means no count is provided here; it says nothing about whether the trade exists or requires a license. These category counts are not reconciled with the headline roster totals.
Figures use separately generated snapshots: overall roster totals, trade counts and mapped-city counts can differ in scope and collection time and should not be added together or treated as a reconciled census. The displayed source refresh date does not date every aggregate. Population and households are sums of the covered ZIP estimates. The income indicator is a population-weighted average of ZIP-level household-income medians, not the state's household median. Census context can refer to a different period from the roster. Housing-unit authorizations refer to the displayed permit year; they are not completed projects. See the ACS estimate guidance and Building Permits Survey for the underlying statistical definitions.
