TL;DR
U.S. factory employment reached a record 19.6 million in June 1979 and stood at a preliminary 12.7 million in October 2026, according to the source’s account of federal data. Manufacturing output was nearly twice its 1979 level in September 2026, but remained about 9% below its 2007 peak. The source also says imports from China contributed to job losses, but do not explain the full decline.
A new report tracking factory employment across the United States, Germany and China finds that U.S. factory jobs have fallen 35% from their June 1979 peak, even as manufacturing output in September 2026 stood at nearly twice its 1979 level. The figures complicate claims that industrial work simply moved overseas: the report says the U.S. decline began well before China joined the World Trade Organization, while also citing research that Chinese imports contributed to some later losses.
The report, published November 8 by ThorstenMeyerAI.com as Episode 6 of its “Work After Work” series, uses U.S. Bureau of Labor Statistics payroll employment figures. Those figures count jobs on employer payrolls outside agriculture, rather than individual workers; they exclude self-employed people and private-household employees. The series begins in 1939. It records 19.553 million factory jobs in June 1979, the highest monthly total in the series, compared with a preliminary 12.7 million in October 2026.
Manufacturing’s share of payroll employment peaked earlier than its job count. Factories accounted for 38.8% of U.S. payroll jobs in November 1943, then 21.7% in June 1979 and 8.0% in October 2026. The report says employment fell particularly sharply from January 2000 to February 2010, when the count dropped from 17.3 million to 11.4 million. It later recovered somewhat, with a temporary decline during the 2020 pandemic shock.
Output followed a different path. Using the Federal Reserve’s manufacturing industrial production index, the report compares a reading of 50.4 in June 1979 with 98.4 in September 2026, with the index set to 100 for 2017. That is about 1.95 times the 1979 level. The report’s rough comparison of output and job counts implies about three times as much output per factory job, but it does not measure hours worked or productivity per hour. It also notes that output has not returned to its December 2007 peak of 108.6.
Fewer Factory Jobs, More Output
The figures show why factory employment and industrial production should not be treated as the same measure. Manufacturing can produce more than it did decades ago while employing fewer people, reflecting changes in how much output each job represents. The report’s comparison is approximate: it divides an output index by employment counts, not by hours worked, and does not isolate the causes of the change.
The distinction matters for workers and communities that use factory job totals as a measure of industrial strength. The sector’s payroll share is now 8.0%, or about one job in 12, according to the report’s October estimate. At the same time, the output comparison is not evidence of an uninterrupted rise: U.S. manufacturing production remains below its 2007 high. The report therefore describes a long employment decline alongside a more mixed production record.
The account also puts current debate about artificial intelligence in a longer history of changes to industrial work. It does not provide evidence that AI caused the historical job losses or forecast how many jobs AI might affect. Instead, it establishes a baseline: factory employment had been retreating for decades before today’s AI debate, while the relationship between jobs and output shifted over time.

A Long Decline Across Economies
The U.S. timeline begins with 9.1 million factory payroll jobs in January 1939. During World War II, the count rose to 16.6 million by November 1943, when factories accounted for their largest recorded share of payroll employment. After the war, the share fell even as the total number of jobs grew, reaching its record in June 1979. The report cites economist Colin Clark’s 1940 observation that the share of workers in secondary industry tended to rise to a maximum and then fall; “secondary industry” can include construction, energy and mining as well as factories.
The source says the U.S. decline was not solely a story of production moving to China. Factory employment began falling before China joined the WTO in 2001. It cites economists’ estimates that rising Chinese imports cost up to about one million U.S. factory jobs between 1999 and 2011, out of almost six million jobs lost from January 2000 to February 2010. These are estimates about one contributing factor, not a complete accounting of the decline.
The report also describes declines in industry’s share of employment elsewhere, while warning that country measures differ. In Germany, the producing sector—which includes manufacturing, construction, energy, water and mining—accounted for 49.2% of workers in West Germany in 1965 and 22.9% in Germany in 2025. For China, it says industry and construction employment peaked at 232 million in 2012. Those figures are not directly interchangeable with the U.S. factory payroll series because they cover broader sectors and use different national statistical measures.

What the Job Figures Leave Open
The October 2026 U.S. employment figure is identified as preliminary, and the report does not give a final revised count. Its output-per-job comparison is explicitly rough: it compares an industrial production index with payroll job totals, not hours worked, worker productivity or the mix of goods produced. It cannot show, by itself, how much of the change came from automation, offshoring, demand shifts, business closures or other factors.
The China-related job-loss estimate is attributed to economists but is not accompanied in the supplied material by study names or methods, making it difficult to evaluate the range independently. The source also provides limited detail on China’s employment measure and does not set out a comparable output series for Germany or China. Finally, although the report’s title links factory work with the age of AI, the supplied figures do not measure AI’s effect on industrial employment or establish what its future impact will be.
The Next Employment and Output Readings
The immediate data milestone is the next release of U.S. payroll employment figures, which may revise the preliminary October 2026 factory count. Subsequent Federal Reserve industrial production readings will show whether output remains below its 2007 peak or moves closer to it. Those series track different things: employment counts payroll jobs, while the production index tracks factory output adjusted for prices.
To assess any effect from AI, later reporting would need evidence that distinguishes AI adoption from other changes in production and employment, such as company-level staffing data, adoption measures and changes in hours or output. The report provides a historical comparison, not a forecast or a finding about AI-driven job losses. Until more direct evidence is available, the scale and direction of AI’s effect on factory work remain unsettled.
Key Questions
How many U.S. factory jobs were there at the 1979 peak?
The report gives a seasonally adjusted peak of 19.553 million jobs in June 1979, commonly rounded to 19.6 million.
How many factory jobs did the United States have in October 2026?
The report lists 12.7 million U.S. factory payroll jobs in October 2026. It labels that figure preliminary.
Did U.S. manufacturing output also fall after 1979?
Not over the full period in the report’s comparison. The Federal Reserve manufacturing index was 1.95 times its June 1979 level in September 2026. However, September 2026 output remained about 9% below the December 2007 peak cited in the report.
Did factory jobs move to China?
The report says rising Chinese imports contributed to U.S. job losses: economists estimate they cost up to about one million factory jobs from 1999 to 2011. It also says the broader U.S. decline started before China joined the WTO, so imports do not explain the full retreat.
Does the report show that AI is causing factory job losses?
No. It provides historical employment and output figures but does not measure AI adoption or attribute past job losses to AI. Its data do not establish how AI will affect factory employment in the future.
