The ability of infant mortality and health indicators to monitor health conditions in early infancy, and their broader use as indicators of the general level of socio-economic development are discussed from three points of view. These are: (i) the increasing impact of differences in legal definitions of live and stillbirths on the comparability of the infant mortality figures produced by vital statistics; (ii) the validity of mortality measures to monitor health; (iii) the comparability of social inequalities in infant health and mortality over time and across countries.  相似文献
