Gender is an enum and is used by the Person model.
The following types are supported out of the box:
| Type | Stored As | Notes |
|---|---|---|
| UNKNWON | NULL | (default) if the value is unset/null it returns as UNKNOWN, see Nullable Enums |
| FEMALE | 'f' | |
| MALE | 'm' |
If you want to extend this (eg. third sex) list see Extending Enums in Concord's documentation.
