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.

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.

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.
