How this ranks: Its Census employment total exceeds 15% of that same 801-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.
