Lift, the sector share over the universe shareof 91,776 in this sector and 53,578,213 in the indexlanding 1 Sept 2026

Computed here, not served: the sector share is the companies the industry profile returns for the technology over the 91,776 in this sector, the universe share is the catalogue's live company count for the same technology over the 53,578,213 in the index, and the lift is the first divided by the second. It is computed over the 10 technologies most common in this sector, so every lift here sits near 1.0; the values worth reading live further down a ranking the API does not serve yet.

Not a segment filter yet

POST /v1/lists/count takes a NAICS code, and NACE is not a filter key it accepts. It ignores a key it does not know rather than refusing it, so a segment under this code would count the whole index under a sector URL. The answer above is counted through the industry profile instead.
