National Security Study Memorandum 200

National Security Study Memorandum 200: Implications of Worldwide Population Growth for U.S. Security and Overseas Interests (NSSM200), also known as the "Kissinger Report", was a national security directive completed on December 10, 1974 by the United States National Security Council under the direction of Henry Kissinger following initial orders from President of the United States Richard Nixon.

NSSM200 was reworked and adopted as official United States policy through NSDM 314 by President Gerald Ford on November 26, 1975. It was initially classified for over a decade and has been part of the public record since 1985. The memorandum and subsequent policies developed from the report were observed as a way the United States could encourage human population planning to slow down global population growth in rapidly growing populations of Lesser Developed Countries. The document describes US security interests in natural resource supplies as a motivator for assisting LDCs in curbing population growth rates. It contemplated that situations arising from scarcity of food and other economic preconditions for stable growth in LDCs could lead to political instability which could put in jeopardy supplies to industrialized countries of key minerals and other resources for their growth.
