Birmingham labor market for wood deck
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 Birmingham is 0.83 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $24.23 an hour, which is 17% below the national $29.12. The middle half of them earn between $22.00 and $28.95 an hour. BLS counts 1,660 of them working in the area, 31.9 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
Construction laborers (47-2061), 20% of the weighting: a median of $18.45 an hour, 19% below the US median of $22.66. The middle half of them earn between $15.51 and $22.60 an hour. About 4,780 work in the metro. That is 91.9 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 carpenters on your job are paid at the 75th percentile ($28.95 an hour) instead of the median, the labor line grows by about $640. At the 25th percentile ($22.00) it shrinks by about $300. The total moves by 6.3% or 3.0%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 520,290 jobs in the Birmingham area. That makes it the 50th largest of the 300 metros we cover, with 0.33% of US employment.
