The Bolivia Demographic and Health Survey (Encuesta Nacional de Demografía y Salud 1989 - ENDSA) was carried out by the Instituto Nacional de Estadística (INE) with technical assistance from the Institute for Resource Development (IRD). The survey was part of the worldwide Demographic and Health Surveys Program supported by the United States Agency for lntemational Development. The purpose of the survey was to collect data on a national sample of women (and their children under five), from which estimates could be made regarding fertility levels and trends, fertility preferences, knowledge and use of family planning, indicators of maternal and child health, and infant and child mortality levels.
A nationally representative sample of 7923 women 15-49 years of age were interviewed in the Bolivia DHS survey (ENDSA) between February and July 1989. The information about child health is based on live births to these women during the preceding five years. For purposes of the survey, the sample was designed to provide representative estimates for the nine departments, with the exception of Beni and Pando which, due to their low population density, were treated as one entity. For this report, the departments were grouped according to region: La Paz, Oruro and Potosf in the Altiplano; Cochabamba, Tarija and Chuquisaca in the Valle; and Santa Cruz, Beni and Pando in the Llanos.
