It may be worth mentioning that pandas Categoricals are mutable and zero-based:

Serialization to SQL and CSV is (also?) lossy, though:

Why the 'start' parameter default is 1? 0 (zero) is more consistent with
other parts of the language: indexes, enumerate, range...
An excerpt from \[1\]:
The reason for defaulting to 1 as the starting number and not 0 is that 0 is False in a boolean sense, but enum members all evaluate to True.
