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.

Pattern

Regional mortality pattern of the UN model life tables.

Code

Canonical short code for the pattern.

Pattern name

Full pattern name.

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.

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.

• Life Table Entropy Keyfitz H Calculator

  Compute Keyfitz' life-table entropy H = e-dagger / e0 from aligned survivor and remaining-life-expectancy columns, including deaths in the terminal age group.

• Coale Demeny Region Family Lookup

  Validate and label a Coale-Demeny regional model life table family (West, North, East or South) at a mortality level from 1 to 25.

• 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.
