Introduction
The Instituto Nacional de Estadística y Geografía (INEGI) is the federal agency responsible for the collection, processing, analysis, and dissemination of statistical and geographic information in Mexico. Since its establishment, INEGI has played a central role in providing data that supports public policy, economic planning, and social development. The organization operates under the auspices of the Secretariat of the Interior and is considered the primary source of official statistics for the country.
History and Background
Founding and Early Development
INEGI was founded in 1983 by a federal decree that merged several existing statistical and geographic entities. Prior to its creation, Mexico’s statistical system was fragmented, with various ministries and institutions collecting data in isolation. The consolidation aimed to establish a coherent, systematic approach to national data collection and to align Mexico’s statistical practices with international standards.
