Sioux City labor market for attic insulation

Wages are the part of this estimate that changes most from town to town. 2 trades carry the job here, and each is compared with its US median. The weighted result for Sioux City is 1.00 times the national level.

Insulation workers, floor, ceiling and wall (47-2131), 80% of the weighting: a median of $23.56 an hour, in line with the US median of $23.62. The middle half of them earn between $22.25 and $28.94 an hour. About 90 work in the metro. That is 12.0 per 10,000 jobs, compared with 2.9 nationally, which suggests plenty of local crews to bid.

Construction laborers (47-2061), 20% of the weighting: a median of $23.38 an hour, 3% above the US median of $22.66. The middle half of them earn between $21.71 and $28.72 an hour. About 560 work in the metro. That is 74.7 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.

At the 25th percentile ($22.25) it shrinks by about $40. The total moves by 6.8% or 1.7%, so wages alone rarely explain a quote that is far outside our range.
