Population data come from INEGI^[1], while population data projections come from the World Population Prospects of 2017, the latest demographic estimates and projections prepared by the Population Division of the Department of Economic and Social Affairs of the Secretariat of the United Nations.

[1] In Mexico, the National Institute of Statistics and Geography (Instituto Nacional de Estadística y Geografia, INEGI) is an autonomous public organisation responsible for regulating and coordinating the national system of statistical and geographic information, as well as capturing and disseminating information about the country in terms of territory, resources, population, and the economy. It also coordinates the National Population Census, carried out every 10 years and inter-census surveys every 5 years. The 2010 Census is the most recent and currently is the most complete source of sociodemographic information in the country, describing the demographic, social and economic characteristics of the population. An inter-census survey conducted in 2015 aimed to generate updated statistical information on the population and housing in the country, which maintains historical comparability with national censuses and surveys.
