Mexico City is growing quickly. In 1970, the city had about 9 million people. Now it has over 17 million. All these people are causing problems for the city. There are not enough jobs. Also, there is' not enough housing. Large families have to live together in small homes. Many homes do not have water. They also do not have bathrooms or electricity. The Mexican government is worried about all these problems. It is working hard to make life better in the city.
Why is Mexico City growing so fast ? Where are all these people coming from? They are coming to the city from the country. Life is hard on the farms in Mexico. Most people on farms have to live a very simple life. They have no extra money for modern things. People think life in the city must be better So they leave their farms and move to Mexico City.
