💉Infant Mortality (per 1,000)

How the Raw Value Is Calculated

The raw value is infant mortality per 1,000 live births. It estimates the probability that a live-born child dies before reaching age one. Lower values are better.

The primary source is World Bank indicator SP.DYN.IMRT.IN. Nomadino uses the latest non-empty annual value for each country; this update uses World Bank data with an API last-updated date of April 8th, 2026 and values through 2024 where available.

The World Bank series is based on estimates from the UN Inter-agency Group for Child Mortality Estimation. It combines civil registration, household surveys, censuses and statistical models to improve comparability where reporting quality differs.

For countries and territories without a separate World Bank series, Nomadino uses maintained replacement values. These are derived from administering state, regional comparators, WHO and UN IGME context, available official series and previous Nomadino values. Replacement values remain visible in the same unit.

The rating is calculated from the raw value on an inverse logarithmic scale: 1 death per 1,000 live births or lower receives 100 points, while 80 or higher receives 1 point. Between those anchors: rating = 100 - 99 * ln(raw value / 1) / ln(80 / 1), rounded to whole points and bounded to 1-100.

The logarithmic scale is appropriate here because differences at the low end remain medically and socially meaningful, while very high mortality would otherwise dominate the whole ranking. A decline from 4 to 2 per 1,000 is therefore visible without extreme crisis values compressing all other countries.

This indicator measures only mortality before the first birthday. Neonatal mortality, under-five mortality, maternal mortality, life expectancy, care quality, vaccination coverage and infectious-disease risks remain separate indicators or plausibility checks.
