The same study reports what the copying costs. Errors and inconsistencies occurred “both within and between rehabilitation centers” - misidentified species, missing causes of distress, missing final dispositions - and incomplete records had to be dropped before anything could be analysed.
Nearly three decades of state records existed and still could not answer basic questions, because they “were collected, but were not in a form conducive for such data summaries.”
Ask a rehabilitator how a year of intake sheets becomes a spreadsheet and you get the same picture from the inside: it gets typed in, one sheet at a time, and it is “tedious” right up until the moment the data finally tells you something.
The entry that is never made at all does not show up in any of these numbers. It is usually the biggest one.
