TL;DR
A November 2026 review from ThorstenMeyerAI.com finds U.S. factory employment fell from 19.6 million in June 1979 to a preliminary 12.7 million in October 2026, even as factory output nearly doubled over that span. The figures describe a long industrial shift, not a measured effect of AI; the source does not quantify how many jobs AI has created or displaced.
U.S. factory employment stood at a preliminary 12.7 million in October 2026, down from its record of 19.6 million in June 1979, while factory output was nearly twice its 1979 level in September, according to a November 8 review by ThorstenMeyerAI.com. The data show how production and headcount have diverged over decades, but do not establish how much of that change was caused by artificial intelligence.
The review uses the U.S. Bureau of Labor Statistics’ Current Employment Statistics, which counts payroll jobs at employers outside farming and excludes self-employed workers and people employed in private households. In June 1979, manufacturing payrolls reached 19,553,000 jobs, the highest monthly figure in the series, which begins in January 1939. By October 2026, the preliminary count was 12.7 million, or 8.0% of all payroll jobs.
The employment share peaked much earlier than the number of jobs. Factories accounted for 38.8% of U.S. payroll jobs in November 1943, during World War II, compared with 21.7% in June 1979 and 8.0% in October 2026. The review says the 1979-to-2026 job decline was about 35%.
Output followed a different path. The Federal Reserve’s manufacturing production index, adjusted for prices, rose from 50.4 in June 1979 to 98.4 in September 2026, with 2017 set to 100. That is 1.95 times the 1979 level. The author estimates that output per factory job was about three times higher, while cautioning that this rough comparison uses job counts, not hours worked. Output has not risen steadily: the index peaked at 108.6 in December 2007 and remained about 9% below that level in September 2026.
Output Rose as Factory Payrolls Fell
The figures show why factory employment alone does not describe the condition or scale of manufacturing. U.S. factories produced nearly twice as much as in 1979 with fewer people on payroll, a shift consistent with higher output per job but not proof that any single technology caused the change. For workers and communities, the employment decline matters even when production remains substantial: fewer factory jobs can mean fewer routes into industrial work and economic pressure in places tied to plants.
The figures also caution against treating automation, including AI, as a complete explanation. The review documents changes in employment and output, but it does not isolate AI’s contribution from other influences, such as machinery, production methods, trade, demand and changes in the mix of goods made. Its account shows that factory employment was falling as a share of U.S. jobs well before the recent wave of generative AI.
There is also a limit to the productivity comparison. Dividing output by the number of jobs does not measure each worker’s productivity precisely: it does not account for hours, job mix or differences between factories. And the fact that total output remains below its 2007 high complicates a simple story of ever-rising production paired with shrinking payrolls.

A Decline That Predates Recent AI
The review traces the shift across several periods. U.S. factory employment rose from about 9.1 million in January 1939 to 16.6 million in November 1943. After the wartime share peak, the proportion of payroll jobs in factories declined, even as the number of workers continued to grow through 1979. Recessions in the early 1980s brought a sharp fall; jobs recovered to about 18.1 million in March 1989 before declining again.
The biggest losses in the source’s timeline came from January 2000 to February 2010, when factory employment fell from 17.3 million to 11.4 million, a loss of almost six million jobs. The review says the count later recovered somewhat, fell briefly during the 2020 COVID-19 shock, and reached 12.7 million in October 2026.
The account places the U.S. experience alongside Germany and China. Germany’s producing sector, which includes manufacturing, construction, energy, water and mining, represented 22.9% of employment in 2025, compared with 49.2% in West Germany in 1965. China’s industry and construction employment peaked at 232 million in 2012, according to the source. These measures use different sector definitions and are not direct comparisons with U.S. manufacturing payrolls.
On trade, the review pushes back against the claim that U.S. factory jobs simply “went to China.” It says the U.S. decline began 22 years before China joined the World Trade Organization. It also cites economists’ estimates that rising Chinese imports cost up to about one million U.S. factory jobs from 1999 to 2011, out of almost six million lost in that period. That estimate concerns trade-related job losses, not the full decline since 1979.
“The number to remember is 19.6 million.”
— ThorstenMeyerAI.com review
The figures do not identify how many factory jobs were displaced, created or changed specifically by artificial intelligence. The review is a historical account of employment and output, not an estimate of AI’s effects. It also does not separate the effects of robotics and other automation from trade, recessions, demand changes, offshoring or shifts in the kinds of products factories make.
The latest U.S. employment count is explicitly preliminary, and the output series ends in September 2026, a month before the employment figure. The source’s estimate of roughly three times as much output per job is a rough ratio, not a measure adjusted for hours worked or workforce composition. The supplied material does not provide a forward forecast or a detailed account of AI adoption at individual plants.
New Data Will Test the Trend
The next evidence to watch is updated BLS payroll data and later Federal Reserve manufacturing output figures. Revisions to the October 2026 employment estimate could change the latest count, while future readings will show whether output moves back toward its 2007 peak or remains below it.
To measure AI’s role, researchers and employers would need more than a national employment trend: they would need information on where AI systems are adopted, which tasks or roles change, and what happens to hiring, hours, pay and production at affected sites. Until those details are available, the historical figures establish the scale and duration of factory employment’s decline, but not AI’s specific contribution.
Key Questions
How many people worked in U.S. factories in October 2026?
The source reports a preliminary 12.7 million factory payroll jobs in October 2026, equal to 8.0% of all U.S. payroll jobs.
When did U.S. factory employment peak?
The BLS payroll series cited in the review reached 19,553,000 jobs in June 1979, its highest monthly figure since the series began in 1939.
Does the report show that AI caused factory job losses?
No. It compares employment and output over time but does not estimate AI’s effect. The review does not separate AI from other possible influences, including other automation, trade, recessions and changes in demand.
How could factory output rise while employment fell?
The review reports that manufacturing output was 1.95 times its June 1979 level in September 2026, despite fewer factory jobs. Its rough output-per-job calculation suggests more output per payroll job, but does not account for hours worked or workforce changes.
Did U.S. factory jobs simply move to China?
The review says trade with China contributed to losses, citing estimates of up to about one million U.S. factory jobs linked to rising Chinese imports from 1999 to 2011. It also says the broader U.S. decline began before China joined the WTO, so that trade estimate does not explain the entire long-term fall.
