The demand for contraceptives will continue to increase for at least the next three decades.  Solely by meeting the existing potential demand of at least 120 million women in the developing world who say that they want to avoid pregnancy but are not using any contraceptive, the prevalence in these countries would rise from 53% to over 60% and the number of users would increase from 384 to 501 million.  Even with no increase in contraceptive prevalence, an additional 100 million couples or more will require family planning compared to 1990 due to the increasing number of women of reproductive age.

With fertility below replacement level in much of the development regions, the attention is generally focused on the less developed ones for the estimation of the future demand; it is estimated that in these countries 536 million couples will be using a contraceptive method in the years to come.  Among them 129 million or more (24%) will have an IUD.

World population reached 6 billion people in the year 2000. The prospects for the future is more alarming: the number of people who will live on the planet at the end of the twenty-first century will vary from 6.4 billion to a maximum of 19.2 billion.
