"Hundreds" is a geographic division, smaller than counties and roughly equivalent to the division "townships" in Pennsylvania and New Jersey. Delaware is the only state which currently uses this division. There are thirty-three hundreds today. The most recent changes to hundreds were in the 1870s when the last two were established: Gumboro in 1873 and Blackbird in 1875. Prior to the 1960s, hundreds were used as voting districts and as units for reporting taxes. The remaining use of hundreds today is in property tax assessments (tax parcel numbers are assigned by hundreds).
