The segments

## Side by side, never added together

| Segment | Drawn from | Median and spread | Scanned | Gated |
| --- | --- | --- | --- | --- |
| [Public companies](https://readinessindex.io/census/2026-Q4/business/public-companies) Every SEC-registered operating company with a security listed on a US exchange, each with the vertical its SIC code gives. | US Securities and Exchange Commission (SEC), with Wikidata and Wikipedia | **53** · 18–78 | 1745/5239 | 700 of 1745 |

There is no single figure for business. Each segment is its own population, and a combined median would be a number about whichever segment has the most sites. How the Census is run, and what it can support, is on the [methodology page](https://readinessindex.io/census/methodology).
