If you have a street address and zip code, you may retrieve the following information: full address (including zip+4), latitude and longitude, time zone (with daylight savings adjustment), carrier route (postal service), address type, congress district, area code and county.
With another click, you may retrieve demographic data for the neighborhood, such as age, race, marital status, gender, average income and average house value.
I can see this tool being used to target neighborhoods for canvassing in the upcoming election. However, it also could be a very useful tool for geolocation, zip+4 and real estate values, to name a few.
The only problem I noted was that the ethnicity breakdown did not include Hispanic. In my neighborhood, this would really skew results.
