in mexico how do rural celebrations differ from celebrations in big cities
In Mexico, rural celebrations differ from celebrations in big cities in many ways. The major difference is that "rural celebration is more serious and spiritual while in big cities celebration is more profane and secular.
This is based on the socio-geographical nature of both regions. The rural area of Mexico is more homogenous with people who are conservatives in attitudes.
On the other hand, the big cities of Mexico have many migrants and are more exposed people. Thus, they have secular attitudes and tend not to be religious in their approach to festival celebrations.
