The population of Mexico City is estimated to be between fifteen and thirty percent working. However, most people do not make enough money to live in this city. The homeless population in Mexico City is uncounted, and there are no official figures. But it's clear that the homeless population has been growing because of the recent economic crisis. The city's "Winter Shelter" took in 500 percent more indigents in December than it did during the entire year before the crisis began. Many do not even stay in the shelter system.
The metro in Mexico City is an underground rail system, which opened in 1969. Today, there are more than three million registered vehicles. Traffic is so congested, it's nearly impossible to travel without getting stuck in a traffic jam. Most travelers use taxis or VW "bugs," but you'll also find dozens of small buses, called peseros. Despite the high pollution levels, Mexico City is aiming for cleaner transportation by replacing the highly polluting peseros with buses powered by alternative fuels. Electric buses are on the way to fill the city's streets with cleaner energy.
In Mexia, there are a few notable statistics that may give you a better idea of the quality of life in the city. For example, 31% of college graduates in the city earned a master's or doctorate degree. Another indicator of a deteriorating economy is the number of evictions. Mexia's rent burden is significantly higher than the state average of 29.3%, and neighboring cities like Hillsboro and Mabank have higher rent burdens. In 2016, a majority of housing units in Mexia were rented to individuals.
