Analyzing Population Growth in Carbondale and Du Quoin with the expansion of the Railroad over 150
years.
Railroads in Illinois
The 1800’s witnessed dramatic expansion of the railroads throughout the United States.
Early Railroad Planning Map for Illinois
1852 - 1854
• Illinois Central Railroad builds railroad line from Cairo to Chicago
• Entrepreneurs in Du Quoin and Carbondale purchase land near the planned rail lines.
• The cities of Du Quoin and Carbondale are surveyed and plots sold to potential citizens.
• Both cities incorporate in 1853• The first train rolls through the cities on July 4th,
1854.

ConclusionsThe populations of Carbondale and Du Quoin can be modeled with a logistic equation that will predict population more accurately that an exponential regression. It appeared that both towns were growing exponentially prior to 1920 due to the fast growth of railroad usage for travel and freight.Carbondale still grew at a near exponential rate due to the expansion of SIU in the 1960’s. Du Quoin’s population leveled off and has shown little change in many years. Has SIU originally located just north of Du Quoin as was discussed, the population curves may be reversed.
