Why vital registration system necessary?

Well first off It protects human rights, empowers individuals, and promotes sustainable development.

Civil status certificates give people proof of their legal identity, age, and social relationships.

Vital registration is a formal recording of vital events such as births, deaths, marriages, divorce, migration, and a host of others.

Basically, it keeps your Identity safe.
