Howell Township was founded in 1836 and was originally included in what are now the Townships of Oceola and Marion and the City of Howell. In 1960, the population was 1,540 residents. The 2020 census reported a population of 7,893. The population has been steadily growing, with the largest growth of 64.8% between 1970–1980.

The mixture of single- and multiple-family residential housing, commercial and industrial properties, and farming creates a comfortable environment to raise a family or conduct business. Students in Howell Township attend Howell or Fowlerville Schools.

Howell Township’s infrastructure includes a wastewater treatment plant. Public water is supplied through the Marion, Howell, Oceola, Genoa Water Authority (MHOG).  A master plan for sewer and water has been formulated by the Township as a tool for future growth. Properties not on public sewer and water are serviced by private septic and wells.
