Each year, about one third of births go unregistered, adding to the growing number of its population who live and die without leaving a trace of their existence and/or their characteristics on any legal document or statistical record. Also, only one in five deaths each year gets recorded. The registration system does not therefore provide the data that can generate reliable estimates of the population size and growth, throwing off critical indicators for planning and monitoring of development agenda, and more specifically the management and delivery of social services, described as “scandal of invisibility”.
