Part of every jobs report comes from businesses that never answered the survey, because the government does not yet know they exist. That part is a model output, not a count.
A coffee shop opens in October. It hires nine people. It is not in the jobs report, because the survey sample is drawn from unemployment insurance records that lag by months, and the government's list of employers simply does not include it yet. Multiply that by every new business in the country and you have a hole the payroll survey cannot see.
