Mexico is a country located in North America and a population of over 126 million people. Its variable climate, as well as its mountain ranges and volcanoes divide the country into three main climatic regions. The north, which is mostly desert, the centeral plateau, characterized by temperate climates and the south with tropical climates and greater precipitation. Its diversity of climates, accelerated urbanization and the intensification of industrial activities have made Mexico one of the countries with the most water stress in the region. This creates multiple challenges regarding water and sanitation management.
A rich source of information for measuring the current state of access to water and sanitation are household surveys. Throughout Latin America and the Carribean, household surveys provide us with representative data of the countries' population, validated by statistical institutes, which allow cross-checking with other social statistics such as area, income, and gender breakdowns.
This page relies heavily on the 2020 National Household Income and Expenditure Survey, which surveyed 89,006 representative households. It collects some water and sanitation related data in accordance with the WHO / UNICEF guidelines; however, it does not allow for correct differentiation between the categories of improved non-piped water or type of sanitation facility.
