The two documents I chose to compare were Alton’s encyclopedia 1880 and 1906. My hypothesis is that the population would significantly increase from the mid-1850’s to early 1900’s. Hence some manufacturing developments were established in 1903, my hypothesis was correct. The population was approximately 12,000 in 1857. In the 1900’s the population in Alton had risen up to 14,210. The visualization I would use to test my hypothesis would be like a timeline graph.
