TL;DR
A November 8 report from ThorstenMeyerAI.com examines the long decline in factory employment alongside changes in manufacturing output. U.S. factory payrolls fell from 19.6 million in June 1979 to a preliminary 12.7 million in October 2026, while factory output was nearly twice its 1979 level but remained below its 2007 peak. The figures document a changing relationship between jobs and production; they do not establish how much of the change was caused by automation or AI.
A November 8 report from ThorstenMeyerAI.com documents a long-running shift in factory work: U.S. manufacturing payrolls stood at a preliminary 12.7 million in October 2026, down about 35% from their June 1979 peak, while manufacturing output was nearly twice its 1979 level in September. The comparison shows that employment and production have moved differently, but the figures alone do not establish how much automation or artificial intelligence caused the change.
The report uses U.S. Bureau of Labor Statistics payroll figures, which count jobs on employers’ payrolls outside farming and exclude self-employed people and private-household workers. The series began in January 1939. Factory employment reached 19.553 million in June 1979, the highest monthly level in that series. By October 2026, the preliminary count was 12.7 million, or 8.0% of all payroll jobs.
Factory employment did not fall in a straight line. It declined during the early-1980s recessions, recovered to about 18.1 million in March 1989, and then slipped again. The sharpest loss in the account came from January 2000 to February 2010, when the number of U.S. factory jobs fell by almost six million, from 17.3 million to 11.4 million. Employment later recovered somewhat, with a brief drop during the 2020 pandemic shock.
Output followed a different path. The report compares the Federal Reserve’s price-adjusted manufacturing production index, which stood at 50.4 in June 1979 and 98.4 in September 2026, using a 2017 reference of 100. That is nearly twice the 1979 level. However, output peaked at 108.6 in December 2007 and remained about 9% below that high in September 2026. The report’s estimate of roughly three times as much output per factory job compares job counts, not hours worked, and should not be read as a direct measure of individual worker productivity.
Fewer Factory Jobs, Different Output
The figures matter because they challenge the idea that factory employment and factory production rise and fall together. U.S. manufacturers were producing more than in 1979 with fewer payroll jobs by 2026, yet output had not returned to its 2007 peak. The record points to a long-term change in the relationship between the size of the factory workforce and the amount produced—not to uninterrupted growth in manufacturing.
For workers and communities, the distinction matters. A factory sector can remain a substantial source of goods and economic activity while employing fewer people than it once did. That affects the number of available production jobs and can change the skills employers seek. The supplied figures do not specify which tasks were automated, how job quality or wages changed, or how many workers moved into other occupations.
The topic is often discussed through automation and AI, but the report’s central evidence is about employment and output over time. It does not isolate AI’s contribution, provide a count of jobs displaced by AI, or compare factories that adopted AI with those that did not. The trend is relevant to debates about technology at work, but it cannot by itself show that AI caused the decline in factory employment.

How Factory Employment Reached Its Peak
The U.S. factory-job share peaked well before the absolute number of jobs did. In November 1943, during the Second World War, factories accounted for 38.8% of payroll jobs, or 16.6 million positions. The share then declined as the wider economy expanded. In June 1979, employment reached its series high of 19.553 million, but factories represented 21.7% of all payroll jobs. By October 2026, the share was 8.0%.
The report also describes changes outside the United States, though its country measures are not directly equivalent. Germany’s producing sector includes manufacturing as well as construction, energy, water and mining. According to Germany’s Federal Statistical Office, that sector employed 22.9% of workers in 2025, compared with 49.2% in West Germany in 1965; the report notes classification changes in the series. In China, the report says industry and construction employment peaked at 232 million in 2012.
The report cautions against attributing the whole U.S. decline to overseas competition. It says the decline began 22 years before China joined the World Trade Organization in 2001. Citing economists’ estimates, it reports that rising Chinese imports may have cost up to about one million U.S. factory jobs from 1999 to 2011, out of almost six million lost during that period. That estimate concerns one possible factor in a much larger employment change.
“The number to remember is 19.6 million.”

What the Employment Figures Cannot Show
The October 2026 U.S. factory employment figure is preliminary and may be revised. The report’s output comparison ends in September 2026, so the employment and production readings do not cover the same final month. The supplied material also does not provide a detailed breakdown by industry, occupation, region, hours worked, pay or worker demographics.
Most importantly, the statistics do not quantify the separate effects of robotics, other automation, AI, trade, recessions, changes in consumer demand or other forces. The report gives an estimate for the effect of rising Chinese imports during 1999–2011, but that estimate is attributed to economists and is not a count of all jobs lost to trade. No AI-specific job-loss estimate or factory adoption measure is provided, so the scale of AI’s effect on factory work remains unclear.
The Next Data and Adoption Measures
The near-term employment count may change when the BLS revises its preliminary October 2026 estimate. Future monthly payroll releases and Federal Reserve manufacturing output data will show whether employment or production has moved materially from the levels reported here. A comparison of those series can track broad changes, but it will not identify their causes on its own.
To measure AI’s role more directly, readers would need evidence about which factories are adopting AI systems, what tasks those systems perform, and how staffing, hours, wages and output change before and after adoption. The report does not provide those measures or identify a specific policy, company announcement or next milestone. For now, its central finding is historical: the United States has far fewer factory payroll jobs than at its 1979 peak, while manufacturing output remains above its 1979 level and below its 2007 high.
Key Questions
How many people worked in U.S. factories at the 1979 peak?
The BLS payroll series recorded 19.553 million factory jobs in June 1979, its highest monthly count in the series described by the report.
How many U.S. factory jobs were there in October 2026?
The report gives a preliminary estimate of 12.7 million factory payroll jobs in October 2026, equal to 8.0% of all payroll jobs.
Does the report show that AI caused factory job losses?
No. It compares employment and manufacturing output over time but does not isolate the effect of AI or provide an AI-specific estimate of jobs displaced.
Was U.S. factory output still rising in 2026?
Output in September 2026 was nearly twice its June 1979 level, but the report says it was about 9% below the December 2007 peak. The figures do not support a claim of uninterrupted output growth.
