Insulation workers, floor, ceiling and wall (47-2131) carry 80% of the labor weighting. BLS does not publish this trade for the Rochester metro, so we used the Minnesota statewide median: $26.13 an hour against $23.62 for the US. The middle half of them earn between $23.05 and $35.24 an hour.
Construction laborers (47-2061), 20% of the weighting: a median of $28.55 an hour, 26% above the US median of $22.66. The middle half of them earn between $22.36 and $43.11 an hour.
