Where the Slidell price comes from

Add the other trades involved and the blended wage index for Slidell is 0.93 (US = 1.00), which puts labor at 36% of the total. BLS does not publish this trade for the metro, so we used the Louisiana statewide median.
On the materials line, the BEA goods price index for the Slidell metro is 93.7 (US = 100). The midpoint materials bill for 1,000 sq ft comes to $1,500, compared with $1,600 at national prices. Permit and inspection fees are scaled by the broader index (92.7) and land at $0 to $0.
Data note: 80% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Slidell. The wage table below marks each row.
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 Slidell is 0.93 times the national level.
Insulation workers, floor, ceiling and wall (47-2131) carry 80% of the labor weighting. BLS does not publish this trade for the Slidell metro, so we used the Louisiana statewide median: $22.76 an hour against $23.62 for the US. The middle half of them earn between $21.48 and $28.29 an hour.
Construction laborers (47-2061), 20% of the weighting: a median of $18.41 an hour, 19% below the US median of $22.66. The middle half of them earn between $16.79 and $22.69 an hour. About 860 work in the metro. That is 87.5 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 ($28.29 an hour) instead of the median, the labor line grows by about $170. At the 25th percentile ($21.48) it shrinks by about $40. The total moves by 7.2% or 1.7%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 98,240 jobs in the Slidell-Mandeville-Covington area. That makes it the 205th largest of the 300 metros we cover, with 0.06% of US employment.
