The simple version

The monthly jobs number is not a count of every job. It is an estimate from a survey of employers, and every survey estimate comes with a range.

The Bureau of Labor Statistics (BLS) says the range on a one-month change is roughly 122,000 jobs either way. September's gain of 29,000 sits well inside it.

The numbers

• Nonfarm payroll employment changed little in September, at +29,000 (Bureau of Labor Statistics, Employment Situation, released October 2, 2026)
• The unemployment rate was 4.2%, up from 4.1% in August, and BLS described it as changed little (BLS)
• The 90% confidence interval for the monthly change in total nonfarm employment is on the order of plus or minus 122,000 (BLS, Employment Situation Technical Note)
• July's change was revised from +21,000 to -10,000, and August's from +162,000 to +133,000 (BLS)
• Over the prior 12 months, payrolls grew by an average of 45,000 a month (BLS)

What the survey can and cannot detect

BLS works at a 90% level of confidence. In plain terms, it is 90% sure the true change falls within about 122,000 of the published number.

BLS gives its own example. A reported gain of 50,000 means the true change could be anywhere from a loss of 72,000 to a gain of 172,000, so it cannot say with confidence that jobs rose at all.

A reported gain of 250,000 is different. The whole range sits above zero, so BLS can say employment very likely grew.

The Real Cost lens on 29,000

Apply BLS's range to September's number.

• The published gain is 29,000.
• Subtract 122,000 and the low end is a loss of 93,000.
• Add 122,000 and the high end is a gain of 151,000.
• Zero falls inside that range, so the survey cannot say whether employers added jobs, lost jobs, or added several times as many.

That is why BLS itself wrote that payrolls changed little. The headline number is the center of a range, and in September the range is wide relative to the number.

What this means

Small monthly changes carry less information than their headlines suggest. A string of months, or a revision, tells you more than any single report.

September's report shows that second point too. The two months before it were revised down by a combined 60,000 jobs.

What this is NOT

This article explains how precise the monthly payroll estimate is. It does not forecast employment, the economy, or Federal Reserve decisions, and it takes no position on whether the labor market is strong or weak. The 93,000 and 151,000 bounds are our arithmetic using the range BLS publishes, not figures BLS published for September. It does not assess whether the change in the unemployment rate was statistically significant, because BLS's published threshold for that assumes a rate near 6%. All September figures are preliminary and will be revised.
