It was first settled by Captain David Scott, who moved there from Ann Arbor in 1833, and platted the land.

The State Legislature formally created DeWitt Township on March 23, 1836.

The first township meeting was held at the house of Captain Scott on April 8, 1836.

In four years, DeWitt Township went from encompassing the entire county to its current boundary.

The county seat remained in DeWitt Township until December 1857 when it was moved to high Hall, in the village of St. Johns, until a new courthouse could be built.

In the early 1900s, the Lansing, St. Johns and St. Louis Railway opened the community to a new era of prosperity.

It was not until 1929 when the town was incorporated as a village, and then was no longer under the full jurisdiction of the township.

However, residential development did not slow, and thus DeWitt began its evolvement into the bedroom community that it is today.

The DeWitt area was ranked as the 75th best place to live in the United States by CNN Money in 2005.

20.1% of all households were made up of individuals, and 7% had someone living alone who was 65 years of age or older.

16.3% of all households were made up of individuals, and 4.4% had someone living alone who was 65 years of age or older.
