GIS/Mapping Services

The Center for Demographic Research (CDR) provides a wide range of demographic and GIS/Mapping services. Our mission is to provide quality data and related technical services in an efficient and cost-effective manner. Since 1996, we have collaborated with a diverse clientele representing large and small organizations in both private and public sectors. We invite you to bring us your data challenges.

The CDR has created an online geographic reference map that contains new and historic geographic reference boundaries from multiple sources. All layers included have point and click identifiers or displayed names. The layers are not downloadable, but agency source information is included if GIS information is desired.
