| Measure | Value | What it means for you |
|---|---|---|
| New housing units permitted | 242 | Last full year, county-wide. 46 per 10,000 residents. Permits lead construction hiring by months, so this is the earliest honest signal of work arriving (Census Building Permits Survey). |
| Construction employment | 623 | Everyone working in construction in this county, all trades and office staff. Average pay $1,199 per week. BLS QCEW. |
| Median year homes were built | 1987 | Older stock means more repair, replacement and retrofit work, which is steadier than new build and does not stop in a downturn (Census ACS). |
