Public bodies, schools, job boards and companies with 50 employees or fewer are left out. ## How We Counted **In short:** We counted engineering firms in Ken's database with headquarters in New York on Oct 17, 2026. - Filter: Companies in Engineering Services or Civil Engineering, with headquarters in New York, United States, and at least one employee on record. - Headquarters only. Companies with just an office in New York 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.
