The document discusses the Human Development Index (HDI), which is a metric developed by the UNDP to measure human development across countries. The HDI assesses dimensions of health, education, and standard of living. Health is measured by life expectancy. Education is measured by factors like adult literacy and school enrollment. Standard of living is measured by GNI per capita. The document also discusses other related indices and defines human development as improving living conditions through increasing assets and rights. It outlines the methodology used to calculate the HDI and concludes that Mexico has seen partial human development progress in health and education but not equally in all areas or regions.
