CBAS Nigeria
An offline-first system that turns community volunteers into a live data source for births that the national registry was never reaching, closing the gap between a home birth in a remote ward and an official record.
What we shipped
Across rural Nigeria a huge share of births happen at home, far from any government office, leaving millions of children invisible to the registry. The community volunteers meant to capture them often have no reliable internet, no technical training, and only basic phones.
CBAS is a lightweight mobile app simple enough for any frontline volunteer, and it works fully offline. It captures the birth location automatically and walks the volunteer through a short four-step form. The moment a signal appears it syncs to the national system, where the local registrar sees the alert on their own map and confirms the birth with the family.
Data Druid gave technical support to the developer of CBAS, the community birth alert system for the National Population Commission. CBAS gives frontline volunteers a phone app simple enough to use anywhere, online or off, and gives registrars a live map of every birth alert waiting to be confirmed, feeding new, ground-truth data into the national system.
