Health

Life expectancy, mortality, healthcare and public-health measures.

Health data is unusually sensitive to definitions, reporting delays and differences in surveillance. Mortality, life expectancy, disease prevalence and service coverage may come from registrations, surveys or modeled estimates. The assets below are selected to keep those source details visible rather than presenting a number without context.

Use this topic page as a route into the reviewed catalog, not as medical advice. Each asset links to its original publisher and records its freshness and reuse conditions. When a measure can change with age structure or testing practice, consult the provider’s metadata before drawing conclusions.

Share of men defined as underweight, healthy, overweight and obese

Share of men (% of adult population), who are underweight, healthy/normal, overweight or obese based on body mass index (BMI). Body Mass Index (BMI) is a person's weight divided by their height squared. The WHO define a BMI <=18.5 as underweight; 18.6 to 25.0 as normal/healthy; 25.1 to 30 as overweight; and >30.0 as obese.

COVID-19 Containment and Health Index

This is a composite measure based on thirteen policy response indicators including school closures, workplace closures, travel bans, testing policy, contact tracing, face coverings, and vaccine policy rescaled to a value from 0 to 100 (100 = strictest). If policies vary at the subnational level, the index is shown as the response level of the strictest sub-region.

Health of fish stocks by fish group

Fish stocks are measured by their biomass: the number of individuals multiplied by their mass. Here it's measured as the biomass of a fish stock divided by the biomass at its maximum sustainable yield – the level at which we can catch the maximum amount of fish without a decline in fish populations. A value of one maximises fish catch without decreasing fish populations.

Average non-HDL cholesterol levels

The estimated average level of non-high-density lipoprotein (non-HDL) cholesterol, commonly known as "bad cholesterol". Healthy levels are considered to be under 4mmol/L. Elevated levels of non-HDL cholesterol are a risk factor for chronic complications, including cardiovascular disease, and premature death.

Exposure to air pollution from human sources

Annual average concentration of fine particulate matter (PM2.5) in the air. These are small particles that are 2.5 micrometers or less in diameter and can cause health problems in humans exposed to high concentrations. This data excludes natural sources of PM2.5, such as dust and sea salt, to focus on human-caused pollution.
