In the early first decade of 20th century in the United Stated, the concept of the communication went hand in hand with social studies which base was quantitative and analytical methods. The Chicago School played a very important role to develop social theories with empirical foundation. They focused on the city as social laboratory.
During those years, the significant trend was the migration of the people to the United Stated from different parts of the World as well as the movement of people from rural to big cities.
It was the time of great growth and significant changes with new opportunities however this mobilities caused social problems, like racism, homicide, suicide, poverty, which were created by the dynamics of the masses. Different people from different cultures and languages were forced to communicate with each other by the social environment.
The Chicago School developed a set of standard assumptions to solve the social problems. The main assumptions of the school were the quantitative methodologies, which were the only method to study on urban social phenomena. This approach was adopted from natural sciences, especially ecological science which is studied on the species behaviors in their environment. The city conditions and using qualitative methods and data brought great richness to the depth of the work. However, the subject was human and his changing nature and applicability of the quantitative data to real life became one of the School’s liability.
