Neonatal Postneonatal Split Lookup
Split the infant mortality rate into its neonatal component (deaths under 28 days) and postneonatal component per thousand live births, with the neonatal share of infant deaths.
Description
Split the infant mortality rate into its neonatal component (deaths under 28 days) and postneonatal component per thousand live births, with the neonatal share of infant deaths.
Split the infant mortality rate into its neonatal component (deaths under 28 days) and postneonatal component per thousand live births, with the neonatal share of infant deaths.1
When to use Neonatal Postneonatal Split Lookup
Use this mortality or life-table method when age intervals, deaths, exposures, survivorship, and open-ended interval assumptions refer to the same population and period.
- Infant deaths
- Total deaths under one year of age.
- Neonatal deaths
- Deaths at ages under 28 days.
- Live births
- Live births in the year.
How the method works
- NMR
- Neonatal mortality rate per 1000 live births.
- PMR
- Postneonatal mortality rate per 1000 live births.
- Share
- Neonatal share of all infant deaths in percent.
Limitations and assumptions
Life-table results depend on age grouping, exposure quality, the treatment of the first and terminal intervals, and assumptions about deaths within each interval. Sparse deaths can make rates unstable.
Alternative or Complementary measures
Complement a summary mortality result with age-specific death rates, survivorship, and exposure counts. A complete life table is preferable when the question involves several ages or remaining life expectancy.
