Looking at what is going on in the country:
Mexico has the second-largest economy in Latin America and is a major oil producer and exporter.
Rural areas are often neglected and huge shanty towns ring the cities.
The Mexican economy is heavily dependent on the money sent home by the millions of migrant workers in the US.
Mexico has one of the highest rates of kidnapping.
Since 2006 35,000 people have died from drug related violence.
Powerful cartels control the trafficking of drugs from South America to the US, a business that is worth an estimated $13bn (£9bn) a year.
