This report presents key findings from a maternal mortality study conducted in the Kassena-Nankana District of northern Ghana in 1997–98. Sibling history data collected in the course of this survey are analyzed together with longitudinal data from the Navrongo Demographic Surveillance System (NDSS). A comparison between mortality data from these two sources indicates that obtaining reasonably accurate estimates of age-specific death rates is possible by using the sisterhood method. Direct and indirect estimates from the maternal mortality study and the NDSS suggest a decline in the maternal mortality ratio for the Kassena-Nankana District from 800 to 600 maternal deaths per 100,000 live births over the past 14 years.
