I was looking at the 2014 data, and was surprised to see that while Q1/Q2 gender is "Male", "Female", or "", in the 3 Q3/Q4 .csv files gender is "0", "1", or "2".
Any idea what do "0", "1", and "2" correspond to?

Also, I noticed that a couple of rides (<200) where usertype = "Customer" (rather than "Subscriber") and gender = "Male" or "Female".
What does it mean for customer (i.e. not subscriber) gender to be known?

Finally,
What does usertype = "Dependent" mean?
