North Dakota labor market for attic insulation
North Dakota's labor line is priced from 2 trades, each compared with its US median wage. After weighting by each trade's share of the work, the state comes out at 0.96 times the national level.
For insulation workers, floor, ceiling and wall (47-2131, weighted 80%) the local median is $22.33 an hour, which is 5% below the national $23.62. The middle half of them earn between $21.15 and $27.33 an hour. BLS counts 260 of them working in the state, 6.1 for every 10,000 jobs (US: 2.9), so the local bench is deeper than average.
For construction laborers (47-2061, weighted 20%) the local median is $23.59 an hour, which is 4% above the national $22.66. The middle half of them earn between $21.96 and $29.17 an hour. BLS counts 5,050 of them working in the state, 117.6 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
A crew paid at the 75th percentile for insulation workers, floor, ceiling and wall ($27.33 an hour) would add about $150 to the statewide midpoint; one at the 25th percentile ($21.15) would take off about $35. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 429,430 jobs across North Dakota (May 2025), which is 0.3% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Insulation workers, floor, ceiling and wall (47-2131) | 80% | $21.15 | $22.33 | $27.33 | $23.62 | 0.95 | state |
