In Pennsylvania, I have to say the number is pretty skewed. I know that a lot of the population is going to be located in Philly + suburbs and their surrounding cities. Eastern Pennsylvania has many more Jews than Western PA, especially with a higher percentage in suburban and urban areas.
I also think the number is heavily inflated. Living right outside of Philly in the suburbs, there are not many Jews left in my area. Some, but not enough to get above 1.5%ish. Most are moving to the more urban areas.
Most of the states on there were in the Northeast megalopolis
