Today we charted the historical development of NYC, primarily in terms of major economic shifts from the pre-industrial (colonial, trade) city to the industrial (factory, production) city to the post-industrial (service) city.  We focused on significant shaping forces like immigration, urbanization, industrialization, technological advances, and de-industrialization/suburbanization, and how these have formed the foundation for the social and economic inequalities that we see today in cities, and in NYC in particular.
