ENUM lets you name the three values: "male", "female", "other". This is 'better' than trying to remember what 0,1,2 mean.

TINYINT is a 1-byte integer. When UNSIGNED, it can hold a value 0..255. When SIGNED (the default), it can hold -128..127.

An ENUM with up to 255 (256?) values takes 1 byte. Beyond that, it takes 2 bytes. (Your case will use one full byte.)
