Local wages behind the labor line
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 Indianapolis is 1.18 times the national level.
Insulation workers, floor, ceiling and wall (47-2131), 80% of the weighting: a median of $28.51 an hour, 21% above the US median of $23.62. The middle half of them earn between $22.15 and $34.36 an hour. About 240 work in the metro. That is 2.2 per 10,000 jobs, compared with 2.9 nationally, so expect fewer local crews to bid.
Construction laborers (47-2061), 20% of the weighting: a median of $24.54 an hour, 8% above the US median of $22.66. The middle half of them earn between $22.00 and $30.09 an hour. About 9,840 work in the metro. That is 89.0 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.
Quotes come from real crews, not medians. If the insulation workers, floor, ceiling and wall on your job are paid at the 75th percentile ($34.36 an hour) instead of the median, the labor line grows by about $180. At the 25th percentile ($22.15) it shrinks by about $190. The total moves by 6.9% or 7.5%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 1,105,170 jobs in the Indianapolis-Carmel-Greenwood area. That makes it the 31st largest of the 300 metros we cover, with 0.71% of US employment.
