This book presents 17 key indicators of sexual and reproductive health outcomes and those that measure access to or use of sexual and reproductive health services. It briefly reviews the theoretical and practical considerations related to indicators, and presents definitions, data sources, collection methods, periodicity of collection, disaggregation, use, limitations and common pitfalls for each of the included indicators. National public health administrators and health programme managers would find this book useful in undertaking standardized monitoring and evaluation of their sexual and reproductive health targets and goals. Standardization of monitoring and evaluation at the country level will facilitate monitoring of progress at the global level.
