The occupation this industry is made of and the occupation carrying the strongest licence are DIFFERENT here, and both are shown rather than one being chosen. Collapsing them is how physicians' offices came to report a 6-jurisdiction gate against a true 52.

Concentration is this occupation's share of employment here divided by its share across every industry we hold — how much this industry is made of that job. Above 8× it is a defining occupation; near 1× it is a job every industry has, like a manager or an office clerk. Which licence gates OPERATING the business depends on the jurisdiction and on how the business is structured, and we do not assert it.
What this page cannot tell you
| Gap |
|---|
| demand density for 35 — CBP suppresses small cells for disclosure |
| licence titles in 35 — none matched 'Water and Wastewater Treatment Plant and System Operators', though it is licensed in 43 jurisdictions nationally. The title differs locally, or the record is held municipally. |
| occupation mix for NAICS 221330 — the labour statistics carry no rows at this level, so everything about occupations here, including the defining occupation and its licence gate, is measured at NAICS 221300, a broader grouping. Establishment counts are for 221330 itself. |
| licence coverage — the register holds 54 of 56 US licensing jurisdictions, and 2,504 of its records carry no jurisdiction at all. A count of 43 is out of 54 searched, not out of 56. The unsearched jurisdictions are not evidence of no licence. |
| bonding_required_usd — no producer, and not estimated |
