The basic thesis of the memorandum was that population growth in the least developed countries (LDCs) is a concern to US national security, because it would tend to risk civil unrest and political instability in countries that had a high potential for economic development. The policy gives "paramount importance" to population control measures and the promotion of contraception among 13 populous countries to control rapid population growth which the US deems inimical to the socio-political and economic growth of these countries and to the national interests of the United States since the "U.S. economy will require large and increasing amounts of minerals from abroad" and the countries can produce destabilizing opposition forces against the US.
