That's about what you get based on our urbanization index, which seems to fit the data pretty well. I think it's not the *number* of contacts above a certain threshold that matters so much as the *amount* of contact, which is a function of space X time. https://t.co/A3PMwQa5vJ — PolitiTweet.org

@NateSilver538 Curious how you got to 50-100%. Commute alone seems like it could push that much higher, for mean if not median.
