Understanding whose births get registered: a cross sectional study in Bauchi and Cross River states, Nigeria.

Background: It is a recognized child right to acquire a name and a nationality, and birth registration may be necessary to allow access to services, but the level of birth registration is low in Nigeria. A household survey about management of childhood illnesses provided an opportunity to examine actionable determinants of birth registration of children in Bauchi and Cross River states of Nigeria.

Methods: Trained field teams visited households in a stratified random cluster sample of 90 enumeration areas in each state.
