NYC In the Eyes of a Sociologist
We live in a city, NYC, which is unique by its cosmopolitan and multicultural environment, with people from different parts of the world, along with their social structures, cultures and heritage. Indeed, NYC provides a great, rich opportunity for a sociologist/social scientist to make observations and conduct research. In this exercise, imagine yourself as a sociologist/researcher, and tell us what social/cultural/political/economic, and the like, characteristics you observe as unique to NYC, in a way that is different from other parts of the U.S and/or other parts of the world. In other words, let us hear how NYC presents itself to you as a social environment that is unique and worth conducting research on.
