Source: US Census County Business Patterns ↗St. Clair County, MI has 2 more pet care services (excluding veterinary) with employees than in 2017 — 7 then, 9 now, up 29%. Nationally the count grew 42% over the same years.
What this doesn't tell you: Census counts how many exist each year, not how many opened or closed. A rise of 2 could be 2 new businesses — or 10 openings and 8 closures. 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 812910 covers non-veterinary pet services: boarding kennels, grooming, daycare, training and pet sitting.
The blind spot: Dog walking is overwhelmingly done by solo operators with no employees, and this count cannot see any of them. What it mostly counts is grooming salons and boarding facilities — premises businesses that a walker does not really compete with.
What this doesn't tell you: A low count can mean an opening — or that there's less local demand for it. This measures how many businesses exist, not how many customers want one, and it can't see solo operators without employees. 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 St. Clair County who would pay for it.
Census counts these as one industry, so the 9 above includes all of them together. It cannot tell you how many are any single one.
