TL;DR
A November 8, 2026, report traces the long decline in factory employment in the United States, Germany and China, alongside rising output per U.S. factory job through 2007. It does not provide evidence that AI caused the historical job losses or quantify AI’s effect on future factory employment; that remains an open question.
A November 8 report on factory work finds that U.S. factory employment has fallen 35% from its June 1979 peak, even as manufacturing output in September 2026 was nearly twice its 1979 level. The figures describe a decades-long shift in industrial work, not an AI-driven job loss: the report offers no measure of how many factory jobs AI has eliminated or may eliminate.
The report, published by ThorstenMeyerAI.com as part of its “Work After Work” series, uses U.S. payroll statistics and Federal Reserve manufacturing output data to examine the gap between employment and production. The 19.6 million factory jobs recorded in June 1979 were the highest monthly count in the payroll series, which begins in 1939. Preliminary data put the October 2026 count at 12.7 million, or 8.0% of payroll employment.
Manufacturing output, adjusted for prices, rose from an index reading of 50.4 in June 1979 to 98.4 in September 2026, using a 2017 base of 100. That is 1.95 times the 1979 level. The report estimates that output per factory job was about three times as high as in 1979, while cautioning that this rough comparison uses job counts, not hours worked. Output did not keep rising throughout the period: it reached a reported high in December 2007 and remained about 9% below that level in September 2026.
The steepest U.S. employment decline came from January 2000 to February 2010, when factory payrolls fell from 17.3 million to 11.4 million. The report says the timing and scale of the decline cannot be explained by one cause alone. It notes that U.S. factory employment began falling long before China joined the World Trade Organization, while citing economists’ estimates that rising Chinese imports cost up to about one million U.S. factory jobs from 1999 to 2011, out of nearly six million lost over that period.
What Automation Changes on the Factory Floor
The history matters to workers and policymakers because factory output and factory employment can move in different directions. Producing more with fewer jobs does not, by itself, establish whether machinery, software, trade, shifting demand or other changes caused a particular job loss. The report documents the long-term pattern but does not isolate the role of AI.
That distinction is important as manufacturers adopt AI tools. Depending on how companies use them, such systems may change particular tasks, help manage production or affect staffing decisions. But the source provides no factory-level data on AI adoption, employment changes following adoption, wages or the number of jobs created alongside any jobs displaced. Its historical figures cannot settle what AI will do next.
The broader stakes extend beyond job totals. A decline in manufacturing employment can affect communities built around plants, while production levels matter to supply chains and the wider economy. The report’s finding that U.S. output remains below its 2007 high also complicates a simple story in which fewer workers automatically mean ever-rising production.

From Wartime Peak to Recent Stagnation
The U.S. factory-job share peaked earlier than the job count. Factories accounted for 38.8% of payroll jobs in November 1943, during World War II. The share had fallen to 21.7% by June 1979, even as the number of factory jobs reached its high, reflecting growth in the overall economy. By October 2026, the preliminary share was 8.0%.
The downturn was not a steady slide. After factory employment fell to 16.7 million in December 1982, it recovered to about 18.1 million in March 1989. It then declined again, with a particularly large drop in the 2000s, a partial recovery in the following decade and a brief fall during the 2020 pandemic shock.
The report also compares different industrial measures abroad. Germany’s producing sector—including manufacturing, construction, energy, water and mining—accounted for 22.9% of employment in 2025, down from 49.2% in West Germany in 1965. China’s industry and construction employment, according to the report, peaked at 232 million in 2012. These figures cover broader sectors than U.S. manufacturing alone, so they are not direct like-for-like comparisons.
“The number to remember is 19.6 million.”

AI’s Job Effects Remain Unmeasured
The report presents historical employment and production figures but does not quantify how many jobs AI has affected, which factory tasks are changing, or whether adoption is increasing or reducing overall staffing. It also does not establish what share of the long decline resulted from automation, trade, recessions, changes in consumer demand or other factors.
The October 2026 U.S. employment count is marked preliminary. The reported output-per-job comparison is a rough calculation based on employment counts rather than hours worked, and the international figures use differing sector definitions. The source material does not provide enough detail to make those cross-country measures directly comparable or to assess AI’s future impact on wages, hiring and production.
Watch Adoption and Employment Data
The next useful evidence will be data that links factory AI adoption to staffing, hours, wages and output, rather than comparisons of broad historical totals alone. Company disclosures, labor statistics and studies that track plants over time could help distinguish AI-related changes from trade, business cycles and other forms of automation.
Readers should also watch for revisions to the preliminary October 2026 U.S. employment figure and subsequent Federal Reserve manufacturing output releases. Until more direct evidence is available, the historical record shows how factory jobs and production have diverged; it does not show that AI caused that divergence or establish what will happen as adoption expands.
Key Questions
How many people worked in U.S. factories at the 1979 peak?
The report gives 19,553,000 factory payroll jobs in June 1979, or about 19.6 million. It identifies that as the highest monthly count in the payroll series beginning in 1939.
How many U.S. factory jobs were there in October 2026?
The report cites a preliminary count of 12.7 million in October 2026, equal to 8.0% of payroll jobs. The figure may be revised.
Does the report show that AI caused factory job losses?
No. It documents employment and output trends but does not measure AI’s contribution to job losses or future employment. The report discusses a range of possible factors and cites estimates related to import competition.
Did U.S. factory output keep rising as jobs fell?
Not throughout the period. Manufacturing output in September 2026 was nearly twice its June 1979 level, but the report says output peaked in December 2007 and was about 9% below that high in September 2026.
Why are the figures for the United States, Germany and China not directly interchangeable?
The measures cover different sectors. The U.S. figures focus on factory employment, while the Germany and China figures cited include industry and construction or broader producing-sector categories. The report cautions against treating them as identical measures.
