Prairie Township, in brief

Wikipedia doesn’t have a history of Prairie Township yet. The photos, dates and memories neighbors add here are how it gets written.

Prairie Township is one of twenty-one townships in LaPorte County, Indiana. As of the 2020 census, its population was 202 (down from 209 at 2010) and it contained 86 housing units. Prairie Township was established in 1903, when it was separated from the northern portion of Hanna Township. The land that would become Cass, Dewey, Hanna, and Prairie Townships was previously part of Starke County, under the name Van Buren Township, and was annexed to LaPorte County in 1842.

Between the 2010 and 2020 censuses its population fell from 209 to 202 (-3%).
