The United Nations Human Development Index (HDI) uses information about a country’s life expectancy at birth (health), expected years of schooling and mean years of schooling (education), and Gross National Income per capita (standard of living) to create a measure that ranges from 1 (very high) to 0 (very low). For 2017, the United States had a value of 0.924, compared to 0.926 for Canada and 0.922 for the United Kingdom – very similar values, although not the highest of all countries.
