Birth registration is the recording of a baby's birth at a local government office. It gives the child an official identity.

Death registration records when a person dies. It helps the government track population changes and health trends.

In Tanzania, these registrations are done at the Ward Executive Office or the District Registrar's Office. Birth certificates are important for children to enroll in school, while death certificates are needed for legal matters.

Immigration records track people who move into or out of a country. These include:

• Immigration: People entering a country to live or work.
• Emigration: People leaving their home country to live elsewhere.

These records are kept at border points like airports, seaports, and land borders. The immigration department records passport details, purpose of travel, and duration of stay.

In Tanzania, population data from the census helps your district know how many new classrooms need to be built. For example, if the census shows that Mbeya Region has many children aged 6–12, the government can plan to build more primary schools there. Birth registration is also needed when you apply for a place in secondary school — without a birth certificate, a child may miss the opportunity to continue their education.
