TL;DR
U.S. factory employment reached a high of 19.6 million in June 1979 and stood at a preliminary 12.7 million in October 2026. Manufacturing output was about 1.95 times its 1979 level in September 2026, but remained below its 2007 peak. The figures show a long-term shift in the relationship between factory employment and production; the source does not establish AI as the cause.
U.S. factory employment fell from a record 19.6 million in June 1979 to a preliminary 12.7 million in October 2026, while manufacturing output in September 2026 was nearly twice its 1979 level, according to a report published November 8 by ThorstenMeyerAI.com. The figures document a major change in the balance between factory jobs and production, but do not show that artificial intelligence caused the employment decline.
The report draws on the Bureau of Labor Statistics’ payroll series, which counts jobs at employers outside farming and excludes self-employed people and private household workers. The series began in 1939. Factory employment peaked at 19,553,000 jobs in June 1979; by October 2026, the preliminary count was 12.7 million, about 35% below that high. Manufacturing accounted for 8.0% of U.S. payroll jobs in October, compared with 21.7% in June 1979.
Employment’s high point came well after factories’ peak share of payroll jobs. That share reached 38.8% in November 1943, during World War II, then declined as the overall economy and service-sector employment expanded. The count of factory jobs continued to rise for decades after the share began falling, illustrating why employment totals and the proportion of workers in an industry tell different parts of the story.
Output followed a different path. The Federal Reserve’s manufacturing production index, as cited in the report, rose from 50.4 in June 1979 to 98.4 in September 2026, with 2017 set to 100. The report calculates that as a 1.95-fold increase and roughly three times as much output per factory job as in 1979. That is a rough comparison of output and job counts, not hours worked or individual productivity. It also has a limit: output peaked at 108.6 in December 2007 and remained about 9% below that level in September 2026.
Fewer Factory Jobs, More Output
The gap between employment and production matters for communities, workers and policymakers weighing the future of manufacturing. A country can produce more than it did decades ago without employing as many factory workers, so output growth alone does not show whether manufacturing jobs are returning or who benefits from production gains. The report’s long-run figures also caution against treating a single employment count as a complete measure of industrial strength.
The numbers do not isolate the causes of the job decline. Automation, changes in demand, recessions, trade and shifts in how companies organize production may all matter, but the material does not quantify their separate effects over the full period. It also provides no factory-level evidence connecting AI adoption to the national employment trend. Readers should not interpret the comparison between 1979 and 2026 as proof that AI replaced a particular number of workers.
The output trend adds another qualification: the rise from 1979 does not mean production has continued increasing without interruption. Manufacturing output remains below its 2007 peak, even as the latest employment count is much lower than the 1979 record. Both measures are needed to describe the current state of U.S. factories.

The Long Decline in Factory Employment
The report traces the rise in U.S. factory employment from about 9.1 million jobs in January 1939 to a wartime jump of 16.6 million by November 1943. The share of payroll employment held by factories peaked in that wartime period. Afterward, the job count climbed for decades, reaching its record in 1979 even as factories made up a smaller share of a growing workforce.
The sharpest decline described in the report came from January 2000 to February 2010, when U.S. factory jobs fell from 17.3 million to 11.4 million—almost six million positions. The count later recovered in part, dropped during the 2020 Covid shock and reached 12.7 million in October 2026, a preliminary figure. The report says output has been broadly flat since its 2007 high.
The comparison is international as well as historical. Germany’s producing sector—defined to include manufacturing, construction, energy, water and mining—accounted for 22.9% of jobs in 2025, down from 49.2% in West Germany in 1965. China’s industry and construction employment peaked at 232 million in 2012, according to the source. These figures use different national definitions and time series, so they are not direct one-to-one measures of factory employment.

What the Figures Cannot Establish
The October 2026 U.S. employment count is labeled preliminary in the source, and the latest output observation is for September. Later revisions could change those readings. The report also does not provide an estimate of how many jobs, if any, were lost specifically because of AI. Its comparison of output per job is described as a rough calculation and does not account for hours worked, changes in the mix of products, or other influences on production.
The source says economists estimate that rising Chinese imports cost up to about one million U.S. factory jobs from 1999 to 2011, out of almost six million jobs lost over that period. That estimate is attributed to economists in the report, not presented as a complete explanation of the decline. The cited material does not name the estimates or detail their methods. It also does not provide the promised fuller account of China’s employment trend beyond its 2012 peak, so the comparison’s current status is not established here.
Upcoming Data Will Refine the Picture
The next updates to watch are revised U.S. payroll estimates and later Federal Reserve manufacturing production readings. Together, they can show whether the October employment estimate changes and whether output moves further from, or closer to, its 2007 high. The report gives no specific release dates or forecast for either measure.
To assess AI’s role, readers would need evidence beyond the long-run totals: for example, information on technology adoption by manufacturers, job changes in affected occupations and the timing of those changes. Until such evidence is supplied, the established finding is a broad historical one—fewer factory jobs than in 1979, alongside output still well above its 1979 level but below its 2007 peak—not a measured AI-driven job loss.
Key Questions
How many people worked in U.S. factories at the 1979 peak?
The payroll series cited by ThorstenMeyerAI.com recorded 19,553,000 factory jobs in June 1979, commonly rounded to 19.6 million.
How many U.S. factory jobs were there in October 2026?
The report gives a preliminary count of 12.7 million jobs, equal to 8.0% of U.S. payroll employment.
Has U.S. manufacturing output kept rising?
Not continuously. Output in September 2026 was about 1.95 times its June 1979 level, according to the cited index, but remained about 9% below its December 2007 peak.
Does this report show that AI caused factory job losses?
No. It compares long-term employment and output figures but does not quantify AI’s contribution to job losses or establish that AI caused the decline.
Did factory jobs simply move from the United States to China?
The report calls that explanation partly true, citing estimates that rising Chinese imports cost up to about one million U.S. factory jobs from 1999 to 2011. It also says the U.S. decline began 22 years before China joined the World Trade Organization, so the trade explanation does not account for the entire long-term decline.
