Economy composition shift

Which sectors gained or lost economic weight?

Compare each broad sector's share of the same 17-sector published universe, then separate share movement from absolute growth and rank movement.

Five-year deltas are published only for rows whose NAICS code and industry label are identical in the 2017 and 2022 Census tables. This strict match is a conservative screening rule, not an official NAICS concordance or evidence of causation. Revenue changes are nominal and are not adjusted for inflation.
