Department of Motor Vehicles - Driver Licenses Outstanding by County
,This data consists of valid license cards and identification cards outstanding (i.e., not expired more than 90 days). The value for identification cards includes both people who only have an identification card and people who have both an identification card and a license. Licenses are not issued by county. This is counting the number of valid licenses with an indicator on the record for the “county of residence” (normally tied to the residence address, but to the mailing address if a residence address is not present).,
