How is the Maternal Mortality Ratio ranking compiled?

A ranking is a snapshot of relative position, not a fixed property of a country, and a few habits make it far more useful to read. Every country shown has a non-null observation for its most recent reporting year, and that year is not synchronised across the table, so two neighbouring rows may describe different points in time. The size of the spread between the top and the bottom tells you whether an indicator is structurally uneven across the world or broadly universal, and that shape is often more informative than any single rank. Where a value is expressed per capita or as a share, currency revisions and population updates can shift positions between releases. Treat the order as a starting point for questions, then open the underlying country profiles to understand why each sits where it does.

This ranking orders 194 countries by Maternal Mortality Ratio, measured in per 100,000 live births. Nigeria leads with 993 (2023), while Norway sits at the bottom with 1. The midpoint country reports 47, so any country below that mark falls in the lower half of the distribution and any above sits in the upper half. The spread between the top and bottom gives you an immediate sense of how unevenly this indicator is distributed across the Health picture.

Maternal Mortality Ratio is part of the Health topic and is collected by World Bank. It is one of more than a thousand country-level indicators we track, drawn from official, publicly available statistical releases that undergo agency review. The most recent observations shown here are from 2023, reflecting the latest release cycle for this series. Because definitions, base years, and methodologies can change, the "Year" column is shown for every row — always check it before comparing two countries whose values come from different vintages.

You can also browse all indicators inside the Health topic from the breadcrumbs above to see which other measures move together with Maternal Mortality Ratio. Data is licensed under CC BY 4.0 from World Bank, which means you may reuse the figures freely in articles, reports, and research so long as you credit the original agency.

How rankings are constructed: every country with a non-null observation for Maternal Mortality Ratio in its most recent reporting year is included; countries with no data for that indicator are excluded from the ranking rather than imputed or interpolated. Ranks are dense (1, 2, 3 with no skips on ties) and ties break alphabetically by country name. The "Year" column carries the observation vintage because the world is not synchronous: some countries publish a 2024 figure for this indicator while others only have a 2021 or 2019 reading, depending on each statistical agency's release cycle and the country's own reporting compliance. We never carry-forward a stale year to make the ranking look complete.

What the spread tells you: when the gap between the top and bottom of a ranking is wide — say a 50× ratio between the leader and the median — the indicator is structurally uneven across the global income gradient. When the spread is narrow — a 2-3× ratio — the indicator is more universal, reaching most economies regardless of GDP per capita. Comparing the spread of Maternal Mortality Ratio against peer indicators in the Health topic is the fastest way to see which dimensions of development are converging globally and which remain stubbornly polarised.

Cross-checks before citing: if you plan to cite a figure from this ranking, open the source country's profile and confirm the year, the unit of measurement, and whether the underlying definition has changed in recent revisions. World Bank publishes definition notes alongside every series; the Health chapter of the WDI metadata document is a good place to verify the boundaries of the variable. Be especially careful with per-capita figures (population denominators get revised after each census), GDP figures (PPP vs current-USD vs constant-USD make order-of-magnitude differences), and health indicators that switch between crude rates and age-standardised rates between releases.
