The purpose of this paper is to examine public discussion in Central America of its rate of population growth, and to consider the related question of international migration into the region. These will then be considered within the setting of the problem of economic integration in Central America.The first of the published discussions to be considered is the writer's Reporte preliminar: Necesidades y recursos de El Salvador relacionados a diferentes tasas de crecimiento de población, published in San Salvador in 1956, and which will be hereafter cited as the 1956 Progress Report. The second is a study prepared under the auspices of the Economic Commission for Latin America of the United Nations on Los recursos humanos de Centroamérica, Panamá y México en 1950-1980 y sus relaciones con algunos aspectos del desarrollo económico. The third is a paper entitled La población salvadoreña, presented to the Primer Seminario Latino-Americano de Planificación de Familia in New York (June 4 to 15, 1962) by Drs. Roberto Pacheco and José Francisco Molina.
