TL;DR
U.S. factory employment peaked at 19.6 million in June 1979 and stood at a preliminary 12.7 million in October 2026, while manufacturing output was nearly twice its 1979 level in September. The source says output has remained below its 2007 peak, and that trade with China accounts for part, but not all, of the job losses. Its data describe a long shift in factory work; they do not establish AI as the cause of the decline.
U.S. factory employment stood at a preliminary 12.7 million in October 2026, down from a record 19.6 million in June 1979, according to a report published November 8 by ThorstenMeyerAI.com. Yet the Federal Reserve’s manufacturing output index was nearly twice its June 1979 level in September 2026, a divergence that captures how factory production and factory payrolls have moved in different directions. The figures describe a decades-long change in industrial work; they do not show that AI caused the employment decline.
The report uses the U.S. Bureau of Labor Statistics’ Current Employment Statistics, which counts payroll jobs at employers outside farming. The series begins in January 1939 and does not include self-employed workers or people employed in private households. Factory jobs reached 19.553 million in June 1979, the highest monthly count in the series, then fell to 12.7 million in October 2026. The October estimate is preliminary.
The share of payroll jobs in factories peaked earlier than the number did. In November 1943, factories accounted for 38.8% of U.S. payroll jobs; in June 1979 their share was 21.7%, and in October 2026 it was 8.0%. The report describes the 1979-to-2026 employment drop as about 35%.
Manufacturing output, measured by the Federal Reserve’s price-adjusted industrial production index, was 50.4 in June 1979 and 98.4 in September 2026, using an index with 2017 set to 100. That is about 1.95 times the 1979 reading. The report says output per factory job was roughly three times as high as in 1979, a rough comparison based on job counts rather than hours worked. Output, however, was still about 9% below its December 2007 peak.
Fewer Factory Jobs, More Output
The figures challenge the idea that factory employment and industrial production necessarily rise and fall together. The United States had millions fewer factory payroll jobs in 2026 than in 1979, while its measured manufacturing output remained well above the 1979 level. This is relevant to debates about productivity, the quality and availability of industrial jobs, and how economic growth can continue without a return to earlier factory headcounts.
But the longer comparison can obscure more recent weakness: output has not exceeded its 2007 high, according to the report. Nor does the output-per-job calculation measure worker productivity in a strict sense. It compares an output index with payroll job counts, not the hours people work or the range of products made. The figures show a broad divergence, not a complete account of why it happened.
The title’s reference to AI should also be read cautiously. The source provides historical employment and output data but does not report a measurement of AI’s effect on factory hiring. The evidence presented cannot establish that AI caused factory work to rise or recede.

The report traces two different U.S. milestones. Factory work reached its largest share of payroll employment during World War II: 16.6 million jobs and 38.8% of payroll employment in November 1943. The share then fell, even as the total number of factory jobs rose with the expanding economy. Employment was still 16.3 million in June 1953 and reached about 18.4 million in January 1970 before setting its record in June 1979.
After the 1979 peak, employment fell during the early-1980s recessions, recovered in the late 1980s, and declined again. The steepest period in the series described by the source came from January 2000 to February 2010, when the count fell from 17.3 million to 11.4 million—nearly six million jobs. Employment later recovered somewhat, dropped briefly during the 2020 COVID-19 shock, and reached the preliminary October 2026 count.
The report also points to declines in Germany and China, while cautioning that national measures differ. West Germany’s industry-and-construction sector accounted for 49.2% of workers in 1965; the comparable producing-sector share for unified Germany was 22.9% in 2025. China’s industry-and-construction employment peaked at 232 million in 2012, according to the source. Those figures provide international context, but they are not directly interchangeable with the U.S. factory payroll series.
“The number to remember is 19.6 million.”

AI’s Role Is Not Measured
The source’s central figures are historical employment and output measures, not an estimate of AI-driven job losses or gains. It does not provide data on factory AI adoption, jobs displaced or created by AI, or how much of the output change came from automation, other technology, trade, demand, or changes in what factories produce. AI’s specific contribution remains unestablished by the evidence presented.
The October 2026 U.S. payroll count is preliminary and may be revised. The output comparison also has limits: the report compares an index of manufacturing output with the number of payroll jobs, rather than hours worked, and labels its estimate of output per job a rough calculation. Cross-country comparisons use different sector definitions, and Germany’s statistical office notes classification changes that affect the historical series.
The report says economists estimate that rising Chinese imports cost up to about one million U.S. factory jobs between 1999 and 2011, out of nearly six million lost over that period. That is an attributed estimate, not a finding that trade explains all of the decline. The source notes that the U.S. employment decline began 22 years before China joined the World Trade Organization, in 2001.
Revisions and Causes to Track
The immediate data point to watch is whether the October 2026 payroll estimate changes when the BLS revises it. Subsequent monthly employment releases can show whether the recent factory-job count is rising, falling, or holding near 12.7 million. Later Federal Reserve output readings will also help establish whether manufacturing production has moved closer to or farther from its 2007 peak.
To answer the AI question, readers would need evidence beyond the long-run series: for example, factory-level data linking AI adoption to staffing, hours, output, and changes in production. The report does not give a date for such an analysis or identify a forthcoming study. Until comparable evidence is available, the historical trends can set the scale of the change but cannot assign its cause to AI.
Key Questions
When did U.S. factory employment peak?
The BLS payroll series cited by ThorstenMeyerAI.com reached 19.553 million factory jobs in June 1979, its highest monthly count. The source rounds that figure to 19.6 million.
How many factory jobs did the United States have in October 2026?
The report gives a preliminary count of 12.7 million in October 2026, equal to 8.0% of U.S. payroll jobs. The estimate may be revised.
Did manufacturing output fall along with factory employment?
Not across the whole period measured. The Federal Reserve index cited in the report was about 1.95 times its June 1979 level in September 2026, even as factory payroll employment declined. Output remained about 9% below its December 2007 peak.
Does the report show that AI caused factory jobs to decline?
No. It tracks employment and output over time but does not measure AI adoption or estimate AI’s effect on factory jobs. The data presented cannot establish AI as the cause of the decline.
How much of the U.S. job loss does the source attribute to Chinese imports?
The source cites economists’ estimate that rising Chinese imports cost up to about one million U.S. factory jobs from 1999 to 2011, out of nearly six million lost during that period. It presents this as a partial contribution, not an explanation for all factory-job losses.
