<strong>Influence</strong> <strong>of</strong> <strong>Passenger</strong> <strong>Rail</strong> on the BosWash Megalopolis Corridor
Figure 4- Population Density by Counties in 1910 (Gottmann, 1961)
Figure 3 (1880) shows that individual cities, as represented by counties, began to grow and join
together, but the interconnection between cities to form one “large city” didn’t develop until
around 1910, as shown in Figure 4. In 1920, the most populated city in Megalopolis was New
York City with a total population <strong>of</strong> approximately 5 million residents, followed by Philadelphia
with approximately 1.5 million residents. Figure 5 compares the population <strong>of</strong> major cities <strong>of</strong>
Megalopolis to the United States. New York City is not only the most populated within the
Megalopolis corridor, but also, throughout the entire United States. The city with the second
highest population in Megalopolis, Philadelphia, ranks third in the United States behind Chicago.
