What's the big streak at 1000-1031, 1100-31 and 1200-1231?
It could be brith date, but why only 10-12 specifically? I thought birth months were more normal distributed.
Lotta baby making going on in winter months.
I think that's the overlap between the dense region of PINs that start with 11, 12, or 13 (similar to the dense regions that start with 21, 22, 23, 31, etc), and the dense square region of month+day dates.
I got a PIN assigned by my bank back in the 1980s, and it is in that range. I always assumed it was random, because how easy is it to generate a 4-digit random number? But maybe they gave out PINs more like safe combinations. I don't think you could change them back then, either.
I think that specific block is also more likely to be a street address in a city. So it has two reasons to be common easy to remember numbers.
