	The '''fertility''' of an individual female is defined as the number of live ~~births~~ of babies to that female. Note that the term '''fertility ''rate''''' is typically used when talking about aggregating fertility values across populations, but we simply talk of ''fertility'' when referring to a particular individual female. The fertility of an individual female is a nonnegative integer, i.e., it could take values 0, 1, 2, ... Due to biological considerations, it typically would not exceed 20 (there are only about 32 females in recorded history who have had more than 20 children, according to [[Wikipedia:List of people with the most children\|Wikipedia's list of people with the most children]]).
