ABSTRACT
This paper describes the challenges faced by researchers who conduct GIS mapping analyses using ADAM data where address information has been limited to the zip code level. A recent Oklahoma City ADAM addendum on domestic violence collected more specific address information about the female arrestees participating in the regular ADAM project. The addendum data set stores the address information at the block level to protect the confidentiality of the participants. The paper presents maps based on residential address information using the ADAM zip code data and the more precise block level data contained in the addendum. The authors compare the differences and similarities in the findings. They also address the issues surrounding the protection of human subjects while collecting such sensitive information.
