Source: US Census County Business Patterns ↗Mills County, IA had 4 janitorial and cleaning services with employees in 2017 and 4 in 2023 — little changed. Nationally the count grew 14% over the same years.
What this doesn't tell you: Census counts how many exist each year, not how many opened or closed. A count that barely moves can still hide plenty of churn underneath it. It also can't see solo operators without employees, in any year.
Series runs 2017–2023. Earlier vintages exist but are not comparable: Census changed which small counties it publishes after 2016, so including them would show counties losing an industry that never left.
Census code 561720 covers janitorial and cleaning services — everything from commercial office-cleaning contractors to residential house-cleaning companies, counted as one industry.
The blind spot: This code is dominated by commercial janitorial contractors cleaning offices on contract, which is a different business from cleaning houses. A high count can mean the county has plenty of office cleaners and very few residential ones.
What this doesn't tell you: A low count can mean an opening — or that there's less local demand for it. This counts how many businesses exist, including sole proprietors, but not how many customers want one. Treat it as a lead to check, not a verdict.
County Business Patterns counts establishments with paid employees. A solo operator with no payroll — the most likely competitor for most of these businesses — is invisible to it, in every county, including this one.
Fewer of these per resident than the country average is a reason to look, not a reason to start. The two explanations the data cannot separate are “nobody has served this yet” and “there is less to serve here” — a county with few pool services may simply have few pools. The next step is not a business plan, it is ten phone calls to people in Mills County who would pay for it.
Census counts these as one industry, so the 4 above includes all of them together. It cannot tell you how many are any single one.
