Methodology
Source:
U.S. Census Bureau, County Business Patterns 2022, NAICS 3345 (Navigational, measuring, electromedical, and control instruments manufacturing)
Measure
Precision Instrument Plants, ranked highest first across all U.S. countys
(335 ranked in total).
How the headline figure is computed
The top three units' combined count divided by the combined count of all 335 ranked units.
Universe
Places below a 5,000-resident floor are excluded so a median computed on a handful of households cannot top the ranking.
Every figure on this page is computed directly from the dataset named above
by ALEX Intelligence. No figure on this page was written by hand or by a
language model. The query is stated so that anyone can re-run it and obtain
the same table.
