Company-level data from Ken's database, ranked by employee count. This table reads each company's state from its address, so it can include large companies the count above misses because their record stores the state with a ZIP code. Public bodies, schools, job boards and companies with 50 employees or fewer are left out.
How We Counted
In short We counted manufacturing companies in Ken's database with headquarters in Michigan on Oct 17, 2026.
- Filter: Companies in Manufacturing and its sub-industries, excluding oil and gas, telecommunications and power generation, with headquarters in Michigan, United States, and at least one employee on record.
- Headquarters only. Companies with just an office in Michigan are not counted.
- These are companies in Ken's database (250M people and 24M companies), not every company that exists.
- Some records store the state with a ZIP code, and the state filter misses those, so read the count as a floor. The largest-companies table reads the state from each record's address, so it includes them.
- Counts as of Oct 17, 2026. We check them weekly, and the dates move only when a count or a listed company changes.
- Pages publish only at 50 companies or more. Ken is our product, and these counts come from its company database.
