Mention the uses of Vitual Registration System

 NVSS is used to produce important health indicators from birth and death data, including teen births and birth rates, cesarean delivery, preterm birth and infant mortality rates, leading causes of death, and life expectancy. Many vital registration systems record births, deaths, foetal deaths, marriages, divorces and adoptions, as well as recording information on the individual who experiences the event, such as age, religion, occupation etc. These data are then compiled into vital statistics bulletins.

Explanation: HOPE THAT HELPS.

In most countries, a civil registration system is used to record statistics on vital events, such as births, deaths, marriages, divorces and fetal deaths. This government administrative system creates a permanent record of each event.

Explanation:

There are laws in virtually every country for the registration of

vital events. These registered events serve to establish the

occurrence of the vital event and provide prima facie evidence of

the facts about the event and of the relationship between those

involved in the event. As legal documents, the individual records

are placed in a permanent repository until such time that there is

a request for a copy of the record for various juridical and

administrative uses.
