The equation used to evaluate the amount of women who have kids in opposition to those of child bearing age that do not. In many areas of the country, especially urban areas, this ratio is very high due to poverty, economic status, and ignorance of contraception. This is good in determining what city or community is good for a man (or women) not to raise a broken family.
Detroit, Michigan has the highest Bitches With Children Ratio in the nation. 7 out of every 10 women in the city between the ages of 18-29 have at least 1 kid. 80% of them out of wedlock.
