In this visit to the Brooklyn Historical Society we looked at the different types of maps, charts and atlases from the present to those from the 1860s to compare life in Brooklyn. We looked at maps and charts prepared by the Slum Clearance Committee of New York that described the population, density, land sold, businesses, and even crime rates and mortalit
y rates done by census. While my group was analyzing the maps from the population in the Borough of Manhattan in the 1920 we found out that there were major concentrations of people in the east where most of the new businesses were located. as the years passed in the 1930 the maps show how the people was spreading around and moving more to the center of Manhattan and the west still remained with about 20 percent of the population.
We compared some of the maps that show the subway system with those of now-a-days.
