Sub-theme Vital Statistics
Name Neonatal mortality rate
Definition Refers to the number of deaths in live-born infants during the first 28 days of life, per 1000 live births in a given year.
Calculation/Formula (Deaths in children aged < 29 days/ total live births for same period)* 1000
Unit of Measure Deaths per 1,000 live births
Range (eg Age) Infants in first 29 days of life
Assumptions Totals are more useful than M/F data as there is little difference in exposures/ causes of death in these young age groups – only reason for M/F data is if IMR is input for LE
Limitations Should be measured over 3 -5 year aggregate periods with 95% confidence intervals to minimise instability due to the small number of events. Recording of age in vital statistics systems often is not sufficiently detailed to provide reliable data on this indicator.
Purpose/Rationale Mortality during the neonatal period accounts for a large proportion of child deaths, and is considered to be a useful indicator of maternal and newborn neonatal health and care. Generally, the proportion of neonatal deaths is expected to increase as countries continue to witness a decline in child mortality. In countries having made major progress in reducing IMR (through major improvements in EP and nutrition, e.g.), neo‐natal deaths account for the majority of infant deaths.
Preferred Data Sources National Vital Registration System - (which has been verified for completeness) or National Health Information System
Alternative_Data Sources Indirectly: from censuses/ surveys (questions on infants deaths in last 12 months, and application of life‐table analysis). Census and HH surveys (5‐10 year intervals).
Census - HIES - DHS tag Census/DHS
Primary Data Collection System National Administrative Database - Health Information Management Systems (HIS)
Frequency of Data Collection Annual (aggregated over multiple years)
Other agencies countries_ must report to: CHIPS

Comments / Regional Trend Analysis As countries improve vital statistics and civil registration systems, there may be some increases in published measures of mortality (such as IMR) due to improvements in reporting rather than a true increase in mortality rate. Care must be taken in inter
