List of vital rate formulae

1.	Birth Rate =	No. of live Births during the year X 1000 Mid year population
2.	Death Rate =	No. of Deaths during the year X 1000 Mid year population
3.	Infant mortality Rate (IMR) =	No. of Infant deaths during the year X 1000 No. of live births during the year
4.	Maternal Mortality Rate (MMR) =	No. of Maternal deaths during the year X 100,000 No. of live births during the year
5.	Still Birth rate (SBR) =	No. of Still Births during the year X 1000 No. of live births + No. of still births during the year
6.	General fertility Rate (GF Rate) =	No. of live Births during the year X 1000 Mid year female population in the age group of (15-49)
7.	Early Neo- Natal mortality Rate (ENMR) =	No. of infant deaths less than 7 days during the year X 1000 No. of live births during the year
8.	Neo- Natal Mortality Rate (NM Rate) =	No. of infant deaths less than 29 days during the year X 1000 No. of live births during the year
9.	Late Natal mortality Rate (LNM Rate) =	No. of infant deaths of 7 days- 29 days X 1000 No. of live births during the year
10.	Post Natal mortality Rate (PNM Rate)=	No. of deaths of 29 days - 1 year X 1000 No. of live births during the year
11.	Pre- Natal mortality Rate (PM Rate) =	No. of Still Births & Infant death of less than 7 year X 1000 No. of live births during the year
12.	Sex Ratio at Birth (male female)=	No. of Females X 1000 No. of males
13.	Age specific Death Rate=	No. of Deaths in a particular age group X 1000 Mid year population of same age group
