Comparable industry benchmarks

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 97% 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.
