Experts list various reasons that the population has boomed. One is a desire for large families. Experts estimate that twenty percent of the projected growth over the next fifty years- or 660 million people- will come from families that may have access to family planning services but choose to have more than two children. Another reason that the population is growing at a rapid pace is that family planning services are not available to all people. Many governments ban or restrict valuable methods of contraception. In Japan, regulations discourage the use of birth control pills and encourage the use of condoms. However, condoms prove to be only 90-98% effective under the best circumstances, while, if taken correctly, the pill is 99.67% effective against unplanned pregnancy (" 'NO ' and Other Methods of Birth Control" back of pamphlet) This is at least a 1% difference. Therefore, one woman out of one hundred using condoms will get pregnant. That would mean 647,200 women
