In statistics, is there a word for the share of data items that has a value for a certain property? Or in spreadsheet terms, the share of rows that have a value in a certain column?
In Dutch, there is the word "vulgraad" (lit. "filling rate") that means just that but we find it hard to come up with a proper English translation. "Percent non-empty" is the best we came up with yet, but we feel that there has to be a noun like in Dutch.
As an example, given a table of people:
First name Middle name Last name
--------------------------------------------
Theodore Roosevelt
Eddy Van Halen
Peter Stuyvesant
Rutger Hauer
one could say that the middle name field has a vulgraad of 25%.
