Mexico, country of southern North America and the third largest country in Latin America. Mexican society is characterised by extremes of wealth and poverty, with a limited middle class wedged between an elite cadre of landowners and investors on the one hand and masses of rural and urban poor on the other. But in spite of the challenges it faces as a developing country, Mexico is one of the chief economic and political forces in Latin America. Mexico has a developing market economy that is strongly tied to that of the United States, with its major markets and sources of capital. The Mexican economy is one of the more influential in Latin America and has grown rapidly since the 1970s. However, the country’s per capita gross domestic product (GDP) remains far below that of the United States. The Mexican economy depends largely on services—including trade, transportation, finance, and government—which account for about two-thirds of GDP.
