Two-thirds of those people who are illiterate are women and about 200 to 250 million women don't have access to birth control they want, so that they can control their own fertility.
Women, now better educated and with greater control over their fertility, are in the marketplace, too, and married couples have more money, more leisure time and longer lives to spend together.
"I don't believe in birth control. If you want to control your fertility, do it the way God intended: with a cold, loveless marriage." -stephen colbert.
