US ranks 13th in Human Development Index

The Human Development Index (HDI) is a composite statistic used to rank countries by level of "human development" and separate developed (high development), developing (middle development), and underdeveloped (low development) countries. The statistic is composed from data on Life Expectancy, Education and per-capita GDP (as an indicator of Standard of living) collected at the national level using the formula given in the Methodology section below.

Each year since 1990 the Human Development Report has published the human development index (HDI) which looks beyond GDP to a broader definition of well-being. The HDI provides a composite measure of three dimensions of human development: living a long and healthy life (measured by life expectancy), being educated (measured by adult literacy and gross enrolment in education) and having a decent standard of living (measured by purchasing power parity, PPP, income)

Life expectancy at birth, as an index of population health and longevity
Knowledge and education, as measured by the adult literacy rate (with two-thirds weighting) and the combined primary, secondary, and tertiary gross enrollment ratio (with one-third weighting).
Standard of living, as indicated by the natural logarithm of gross domestic product per capita at purchasing power parity.
