No, I wasn't able to find anything explaining the data either. I actually called a couple of offices to ask how complete it was, and nobody knew what to do with me. The first number I could find was the mayor's office. The person who answered transferred me to the DMV, and the lady who answered there had no idea what I was talking about and put me on hold. I hung up after a while. :/
