Premise: Shabbona Township is one of nineteen townships in DeKalb County, Illinois, USA. As of the 2010 census, its population was 1,453 and it contained 603 housing units. The township contains the Chief Shabbona Forest Preserve and Shabbona Lake State Park.
Hypothesis: In 2010, the United States Census Bureau forgot to include Shabbona Township in its census, and the result was that nobody knew how many people lived in the township in Dekalb County, Illinois, USA.
