The Still Birth Rate is defined as the number of still births per thousand live births and still births during the year. Pre-partum still births are those which are occurring before labour, may reflect genetic or gestation conditions, including maternal nutritional status, and exposure to infection and toxins during pregnancy. Intra-partum deaths, those occurring during the birth process, can reflect the circumstances of the birth (including position of the foetus, multiple births, premature delivery, placenta praevia, pelvic deformations and accidents due to interference).
The Neo-natal Mortality Rate (NNMR) is defined as the number of infant deaths of less than 29 days per thousand live births during the year. The neo-natal mortality rate in India is amongst highest in the world and skewed towards Rural India. Non-availability of trained manpower along with poor health infrastructure is one of the major hurdles in ensuring quality health and neo-natal care. Despite a decline in Infant Mortality Rate (IMR), neonatal mortality is more or less static.
The Crude Death Rate (CDR) indicates the number of deaths occurring during the year, per 1,000 population estimated at midyear. Subtracting the Crude Death Rate from the Crude Birth Rate provides the rate of natural increase, which is equal to the rate of population change in the absence of migration. Primary source of data for births and deaths is the registration of births and deaths under Civil Registration System (CRS) of the Office of Registrar General, India (ORGI).
The Crude Birth Rate (CBR) is defined as the number of live births per thousand population. It is usually the dominant factor in determining the rate of population growth. Primary source of data for births and deaths is the registration of births and deaths under Civil Registration System (CRS) of the Office of Registrar General, India (ORGI). Since the reporting of births under CRS is not complete, ORGI estates CBR annually through Sample Registration System, a large scale demographic Survey Conducted by them.
