These links are calculated from the current national dataset. They are comparison paths, not recommendations or evidence that businesses operate alike.
How this ranks: Its Census employment total exceeds 89% of that same 551-industry cohort. Calculated by ranking this industry's reported value against every other industry at the same NAICS digit-level, not the whole dataset: comparing a 6-digit detail industry to a 2-digit sector would mix incompatible scales.
Same NAICS detail level, ordered by the smallest difference in reported Census employment.
