Countries by UHC service coverage index
Canada ranks 1st in the UHC service coverage index with a score of 92 out of 100, while Chad ranks last at 193rd with a score of 26. The 66-point gap between them represents the widest possible spread across 193 countries measured in 2023. This ranking reflects differences in access to essential health services across reproductive, maternal, infectious disease, noncommunicable disease, and health system capacity domains.
Ranking 2023
Analysis
The UHC service coverage index measures how broadly countries provide essential health services to their populations. It is defined as a composite index representing coverage of essential health services based on 14 tracer indicators in the areas of reproductive, maternal, newborn and child health, infectious diseases, noncommunicable diseases and service capacity and access, presented on a scale of 0 to 100 index points. Values are absolute index scores, where higher scores indicate broader coverage. This dataset covers 193 countries, all with data from 2023, representing 100% recency within a seven-year window. All datapoints are classified as official-quality data, and no extreme outliers were detected using a three-standard-deviation threshold. Scores range from 26 to 92, a spread of 253.8%.
The top of the ranking is dominated by high-income countries in North America, Europe, and the Asia-Pacific region. Canada leads at rank 1 with a score of 92. Iceland follows at rank 2 with 90, and Australia, New Zealand, and Norway share rank 3 at 89. South Korea, Singapore, the United Kingdom, and the United States all score 88 at rank 6. Germany and Switzerland score 87 at rank 10. The top 15 positions include only two non-European or non-Anglophone countries outside the Asia-Pacific region: Cuba, which scores 86 at rank 12, and Kuwait, which scores 84 at rank 23. This cluster of high-income nations holds scores between 83 and 92.
Notable anomalies appear in the middle of the ranking. Cuba ranks 12th with a score of 86, placing it above France (rank 38, score 82), Italy (rank 38, score 82), and Greece (rank 70, score 77). Uruguay ranks 16th with a score of 85, ahead of Austria (rank 23, score 84) and Poland (rank 38, score 82). Among middle-income countries, South Africa ranks 85th with a score of 74, while Eswatini, a neighboring country, scores 72 at rank 96. At the lower end, Sub-Saharan African nations occupy most of the bottom 50 positions, with Chad at rank 193 scoring 26, Somalia at rank 192 scoring 30, and Papua New Guinea at rank 191 scoring 32. Ethiopia and Madagascar share rank 189 with a score of 33.
This metric has several limitations specific to its construction. The index is composite, meaning it aggregates 14 tracer indicators, and a country's overall score may obscure uneven performance across individual health domains. Countries with strong performance in some tracer areas but weak performance in others will receive the same summary score as countries with more uniform coverage. The index does not measure health outcomes directly, only service coverage. Reporting reliability may vary across countries, particularly in low-income settings where administrative health data systems are less developed, which could affect the accuracy of underlying tracer indicators. The index also does not capture quality of care, financial protection, or whether services reach all population subgroups within a country.
Methodology
The metric is the UHC service coverage index, sourced from the World Bank World Development Indicators under indicator code SH_UHC_SCI. It is defined as a composite index representing coverage of essential health services based on 14 tracer indicators in the areas of reproductive, maternal, newborn and child health, infectious diseases, noncommunicable diseases and service capacity and access, presented on a scale of 0 to 100 index points. The data year is 2023. The dataset covers 193 countries, all of which have data from within the last seven years, representing 100% recency. All 193 datapoints are classified as official quality, meeting the 70% threshold. No extreme outliers were detected using a three-standard-deviation threshold. The average year-over-year change across the dataset is 1.7%, indicating low volatility. Scores range from 26 (Chad) to 92 (Canada), a spread of 253.8%. The index does not include measures of health outcomes, financial risk protection, or intra-country distributional equity.
