the valley has been inhabited for at least 12,000 years, attracting humans with its mild climate (average temperatures between 12 and 15 °c, or 54 and 59 °f), abundant game and ability to support large-scale agriculture. civilizations that have arisen in this area include the teotihuacan (800 bc to 800 ad) the toltec empire (10th to 13th century) and the aztec empire (1325 to 1521). when the spaniards arrived in the valley of mexico, it had one of the highest population concentrations in the world with about one million people. after the conquest, the spaniards rebuilt the largest and most dominant city here, tenochtitlan, renaming it mexico city. the valley used to contain five lakes called lake zumpango, lake xaltocan, lake xochimilco, lake chalco, and the largest, texcoco covering about of the valley floor, but as the spaniards expanded mexico city, they began to drain the lakes' waters to control flooding. although violence and disease significantly lowered the population of the valley after the conquest, by 1900 it was again over one million people. the 20th and 21st centuries have seen an explosion of population in the valley along with the growth of industry. since 1900, the population has doubled every fifteen years. today, around 21 million people live in the mexico city metropolitan area which extends throughout almost all of the valley into the states of mexico and hidalgo.

unreached people group









































in christianity, an unreached people group refers to an ethnic group without an indigenous, self-propagating christian church movement. any ethnic or ethnolinguistic nation without enough christians to evangelize the rest of the nation is an "unreached people group". it is a missiological term used by evangelical christians. 









































the lausanne committee for world evangelization defines a people group as "the largest group within which the gospel can spread as a church planting movement without encountering barriers of understanding or acceptance." 









































"nation" is sometimes used interchangeably for "people group".
