Installation, Maintenance, and Repair Occupations

Across the 46 of this group's 51 occupations with published Colorado employment, 113,180 Coloradans work in installation, maintenance, and repair occupations (5 more occupations have no published Colorado estimate, so the true total is somewhat higher). Weighted by those published jobs, the group's mean exposure score is 12.4 of 100, and 0.0% of the jobs are in occupations where most or a large minority of tasks overlap with AI capabilities assessed in 2023.

Maintenance and Repair Workers, General; First-Line Supervisors of Mechanics, Installers, and Repairers; Automotive Service Technicians and Mechanics — the largest of this group's 51 occupations in Colorado.

Every statewide figure on this page is computed directly on published BLS OEWS Colorado state data — a different basis from the county estimates elsewhere on this site, which model occupation mixes from industry mix. The one county table below is labeled accordingly.

Plate I

Tier mix within the group

How this group's 51 occupations — and its 113,180 published Colorado jobs — split across the four task-overlap tiers (cuts at 60/45/30 on the 0–100 score scale).

Occupations and published Colorado employment by tier. Suppressed occupations count in the occupation column but carry no employment.
Tier	Occupations	Published CO jobs	Share of published jobs
high overlap	0	0	0.0%
substantial overlap	0	0	0.0%
some overlap	1	4,980	4.4%
little overlap	50	108,200	95.6%

‡ the published rating is zero — below measurable task overlap, a rating floor rather than a claim of total safety; exact values are in the downloads.

Plate III

Where this work concentrates

The six counties where this group is the largest share of local jobs. These county figures are estimates — modeled from each county's industry mix, not published counts (how county estimates are built) — and a share of a small county's job base can rank above a metro county's much larger absolute employment.

Estimated share of each county's jobs in this group, with the estimated job count.
County	Est. share of county jobs	Est. group jobs	Data quality
Moffat	6.3%	286	Partially imputed estimate
Mineral	5.6%	34	Heavily imputed estimate
Weld	5.3%	6,493	Full
Morgan	5.3%	698	Partially imputed estimate
Park	5.3%	165	Partially imputed estimate
Logan	5.2%	407	Partially imputed estimate

Reading these numbers

Exposure is not a job-loss forecast. Scores measure how much each occupation's tasks overlap with AI capabilities assessed in 2023; high overlap can mean augmentation, automation, or neither. The group mean is an employment-weighted average and hides real spread — this group's occupations span every rated tier it lists above.

Two bases, kept apart. The statewide figures join two published datasets directly (Eloundou et al. task ratings; BLS OEWS Colorado state estimates) — where BLS suppresses a value it is excluded, never estimated, so the group employment total is a floor. The county table is the opposite basis: modeled estimates from industry mix — full methodology.
