The thirteenth issue of the Bulletin on Population and Vital Statistics in the ESCWA Region disseminates data on population size and composition, and on vital events, namely fertility, mortality, marriage and divorce in ESCWA member countries for the period 2000-2009. Data were drawn from different national sources including surveys, censuses and civil registration systems and were compiled mainly from questionnaires prepared by ESCWA and filled by member countries. For accuracy purposes, data have been checked for reliability. The production and dissemination of reliable vital statistics being central to optimal planning, the Bulletin aims to encourage member countries to strengthen civil registration systems with a view to producing and disseminating high quality statistics on population and vital events. It also aims to meet the needs of data users, especially researchers, academics and those working in the fields of population, reproductive health and development, by providing a comprehensive picture on population growth and its dynamics in the region.
