National Register Datasets

The Delaware State Historic Preservation Office maintains statewide GIS datasets that show location and cultural/managment information on historic properties (buildings, sites, structures, objects and districts) listed in the National Register of Historic Places for Delaware, including properties which are also National Historic Landmarks.

If you are using a desktop GIS system such as ESRI's ArcView, these datasets are available as ESRI shapefiles in a zipped format. These data are projected in North American Datum, 1983 (NAD83) in meters. If you do not have a GIS system available, click on this ArcExplorer link to download ESRI's free data viewer.

Delaware Hundreds

"Hundreds" are a geographic division, smaller than counties and roughly equivalent to "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 sole use of hundreds today is in property tax assessments (tax parcel numbers are assigned by hundreds) For the full story on Delaware's hundreds visit http://www2.lib.udel.edu/subj/genealogy/resguide/hund.htm
