Hello Everyone,
Our organization is trying to locate a free mapping software program that is easy to use for the purpose of mapping out the locations of youth cited for alcohol consumption, on and off premise alcohol retailers, in order to determine if there are any commonalities with the location of youth attractions (schools, churches, etc). Does anyone know where to obtain software that would fulfill these needs ?

Hi, Barry,
Google Maps may serve your purpose and it's free. You can use it to create your own custom maps and it is already loaded with locations to which you can correlate data (schools, churches, and so on).

Hi all,
Google also came to my mind, however, I am wondering about privacy issues. I am assuming that some of the alcohol citations would be at in-home parties. Would anyone be concerned about violating people's privacy by mapping thier address? I am interested in perspectives because I am working with a nonprofit agency that is looking for ways of documenting its services to the community. However, we can't get around, GIS mapping being inherently to invasive.

Mark,
You are absolutely correct. Geocoding is a very sensitive issue. Data would have to be deidentied. This is an issue typically handled through data use agreements of de-identified sets or limited use data sets. Truly de-identified data sets take care of this issue up front but also potentially exclude the possibility of running important or meaningful analyses. Limited use data sets include more restrictions but more data specificity. Even in a limited use data, one would have to use, for example, only the 629 of a zip code instead of the full 62901 (at least in this type of sensitive data). With an interest in specificity, the only way to get around this issue in this case would seem to be limiting the data set to the inclusion of out-of-residence (home, dorm, apartment, etc.) citations and excluding month and time of the citation. So essentially, you would have citations for things like DUIs, public drunkenness (intoxication), etc. The problem here will be figuring out if either of these offenses could be linked to person or residence. For example, public drunkenness on a person’s own lawn is different than the same offense in the middle of a forest. The best route to take with regard to supporting some level of specificity is to work with an institutional review board. Sometimes universities will permit other entities to go through the university IRB process. The easiest way to do this is team up with a faculty or professional staff member within a university. There are also independent IRBs that offer fee for services reviews; the cost of this service will prohibit many organizations using them, however. The upside to IRB review is that it protects your organization and informs you regarding reasonable ethics and prescriptive laws/regulations. The downside to some IRBs is that some primarily care more about protecting their organization from lawsuits and secondarily about protecting the participants, which leads to some overly conservative protections. Additionally, IRB reviews and ethical decisions vary widely across IRBs—if you bring in three IRB experts regarding a complex ethical issue, you will receive three different opinions (sort of like judges). This variability in decision will likely not be a problem in the case specified in this email string because the issue is very straight forward. I speculate that an IRB will suggest limiting analyses to the county level and/or limiting the subgroups included in the analysis. Analyses and reporting on communities, assuming communities means block level or a highly specified subsection of a city (or even more specific), would likely not be permissible, given the current culture of research ethics. All it takes is one data point to stick out as a unique identifiable case, and it could raise big problems (at least perceived big problems—a lot times the expectations of potential harm are much greater than the actual potential harm); an inevitable outcome of people’s tendency toward loss aversion.
Great points Mark. I would definitely err on the side of caution when dealing with criminal justice or health issues.
With regard to Mark’s issue of documenting services, services may be easier to tackle, depending on what services is operationalized as.
