How to read these figures
- The Census Building Permits Survey counts new privately owned housing units authorized by permits. One permit can cover multiple units. The counts describe authorizations, a stage before starts and completions.
- The published estimate includes reported units and Census estimates that fill gaps. The difference is calculated from those two columns. Reported-only units can include records from approved alternative sources. A missing report can leave an office without a usable count.
- County and state totals come from their own Census files. Permit offices can cover places across county lines or areas served by another jurisdiction. The office’s county field is used for navigation.
- ACS housing inventory and rents are survey estimates for 2020–2024. Gross rent includes rent and separately paid utilities or fuels. Rent burden is the share paying at least 30% of income among cash-rent households with a computed ratio. Margins are at 90% confidence. The margin for rent burden is approximate.
- Vintage 2025 county housing stock is a separate Census series. Its model uses building-permit data alongside other inputs. Read stock change and permits as separate measures.
