Insulation Workers, Mechanical pay in California and Tennessee
The May 2025 BLS OEWS median for Insulation Workers, Mechanical is $119,690 per year in California. It is $46,380 per year in Tennessee. California is 158.1% above Tennessee on the published median.
Both rows use SOC 47-2132 and the same annual wage metric. Median means the middle of each area's published wage spread. It is not one worker's pay. The larger median is not proof that one place gives a better job or a better result. It is one wage fact from one source period.
BLS lists 1,310 wage and salary jobs in California and 670 in Tennessee. Those are survey job counts, not open posts. Read pay, job scale, local share, and price level as separate facts before you make a choice.
