India's Sample Registration System (SRS) 2022 data shows an Infant Mortality Rate (IMR) of 28 per 1000 live births. IMR is defined as the number of deaths of infants aged:

• A 0 to 28 days per 1000 live births
• B 0 to 5 years per 1000 live births
• C 28 days to 12 months per 1000 live births
• D 0 to 12 months per 1000 live births ✓

Explanation

Infant Mortality Rate (IMR) = (Deaths under 1 year of age in a given year / Total live births in the same year) × 1000. It encompasses all infant deaths from birth to under 12 months. Neonatal Mortality Rate covers 0-28 days; Perinatal Mortality Rate covers 28 weeks gestation to 7 days post-birth; Post-neonatal Mortality Rate covers 28 days to 1 year. IMR is a sensitive indicator of socioeconomic development and healthcare quality.
