Just as the conscientious clinician strives to maintain currency in clinical practice, the certified nurse-midwife (CNM) should also be well informed about population-based developments in the state of women's and infants'health and health care. Informative reports on a variety of topics are issued regularly by government agencies and nongovernmental organizations. Currency in this literature can provide the CNM with a sound basis for public education and legislative efforts, as well as a richer context for the care of individual women and infants. In the following article, selected sources of information on women's and infants'demographic characteristics, socioeconomic status, fertility and natality, health, and health care use will be identified. Recent publications will be cited to illustrate the types of information available from government agencies and nongovernmental organizations.
