The Third World Population Conference ends in Bucharest, Romania. At the end of the ceremony, the UN-Romanian Demographic Centre is inaugurated.

The first ever World Population Conference was held at the Salle Centrale, Geneva, Switzerland, from 29 August to 3 September 1927. Organized by the forerunner of the United Nations, the League of Nations, and Margaret Sanger; the conference was an attempt to bring together international experts on population, food supply, fertility, migration and health to discuss the problem of human overpopulation. The conference was organized with funds donated by Sanger's husband, J. Noah Slee, as well as a grant from the Rockefeller Foundation. Sir. Bernard Mallet presided over the meeting, and William H. Welch was vice-president.

August 30 is the 242nd day of the year in the Gregorian calendar; 123 days remain until the end of the year.
