Yep, exactly. The Amish population doubles every 20 years. Simple growth, over time, while everyone else's populations are near flat or shrinking? I give them

Yep, exactly. The Amish population doubles every 20 years. Simple growth, over time, while everyone else's populations are near flat or shrinking? I give them a great chance. That's faster than any other group that I could find. The Census Bureau publishes growth rates by race too - the Hispanic population is growing around 2%, the Black population is growing around 1.5%. (I'm just hoping their attitudes on women and race improve.)
