OP seems to claim 13% same / 87% opposite

  I don't think you can make that conclusion. I think you're making the assumption that all three data points are needed for all 87%. But obviously some people can be uniquely identified based on just {zip, date or birth}, such that gender isn't necessary. So the distribution could e.g. be 8% same, 8% opposite, 5% both, 79% neither, and explain the original numbers without triggering the paradox.

    Yeah I was off, but by their numbers 87% of the time, there are no others on my birthdate or there is one other and opposite gender. 13% of the time is 1 same gender or more of either or both.
