Countries by Infant Mortality 2026

Top Countries Analysis

South Sudan (72.6 per 1k) leads all nations in infant mortality rate. The gap between South Sudan and the 2nd-ranked Somalia (67.8 per 1k) is 7.1%, a difference that reflects deep structural advantages rather than marginal variation. Somalia itself sits 0.6% ahead of 3rd-ranked Niger (67.4 per 1k), indicating that the top tier is not a cluster but a graduated hierarchy. Niger leads 4th-placed Guinea (61.5 per 1k) by 9.6%. Rounding out the top five, Central African Republic records 60.4 per 1k, sitting 1.8% behind Guinea. Collectively, these five countries account for 9.0% of the total infant mortality rate measured across all 195 ranked nations, highlighting how concentrated this metric is at the top of the distribution.

Global Distribution

The median infant mortality rate across all 195 countries is 13.3 per 1k, meaning half the world's nations fall below this threshold. The mean infant mortality rate of 18.8 per 1,000 live births is above the median, indicating a right-skewed distribution driven by high-value outliers pulling the average away from the center of the distribution. The interquartile range spans from 29.9 per 1k at the 25th percentile to 5.0 per 1k at the 75th percentile, a -83.3% spread that captures the typical variation among the middle half of all ranked countries. Countries at the 25th percentile, represented by Tanzania (29.9 per 1k), stand substantially below the median, while countries near the 75th percentile, such as Bulgaria (5.0 per 1k), approach the upper quarter of the ranking. This distributional shape has important implications for global policy comparisons: simple averages overstate the typical country's infant mortality rate when the distribution is right-skewed, and the median provides a more representative benchmark for most nations.

Regional Breakdown

Regional patterns in infant mortality rate are pronounced. Africa accounts for 8 of the top 10 countries by infant mortality rate, led by Somalia, Niger, Guinea. The full top-10 regional distribution is: Africa: 8, Other: 2. At the other end of the ranking, Other represents 5 of the bottom 10 countries, including Iceland, Slovenia, Singapore. The bottom-10 regional breakdown is: Other: 5, Europe: 4, Asia: 1. These geographic concentrations reflect underlying structural factors including historical development trajectories, geographic endowments, and regional integration, rather than any single policy variable.

Bottom of the Rankings

San Marino's infant mortality rate of 1.4 per 1k is 89.5% below the global median of 13.3 per 1k. Estonia's infant mortality rate of 1.6 per 1k is 88.0% below the global median of 13.3 per 1k. Singapore's infant mortality rate of 1.7 per 1k is 87.2% below the global median of 13.3 per 1k. The bottom of the infant mortality rate ranking is predominantly shaped by nations where gaps in skilled birth attendance, clean water, and neonatal care drive high rates of infant death. These low positions do not necessarily reflect recent decline; in many cases they represent long-standing structural conditions that change slowly. Policy interventions, international aid, and regional cooperation have produced meaningful improvements in some bottom-ranked countries over the past two decades, even when those improvements are not yet sufficient to move them out of the lowest tier.

Data Methodology

Infant mortality rate measures the number of deaths occurring among live-born infants before they reach one year of age, expressed per 1,000 live births. The World Bank compiles these estimates primarily from household surveys, demographic and health surveys (DHS), and civil registration systems, supplemented by UN Inter-agency Group for Child Mortality Estimation (UN IGME) modeled estimates where administrative data is incomplete. Countries with weak vital registration systems depend heavily on survey-based estimates, which are conducted infrequently and may not reflect recent policy changes. Infant mortality is a sensitive indicator of access to clean water, sanitation, nutrition, and primary healthcare. Rates below 5 per 1,000 are considered very low; rates above 50 per 1,000 indicate serious gaps in health system coverage. Data typically lags the reference year by two to three years for low-income countries.
