ENS, thanks for the numbers. Here KJ is close enough to Bronx.
I am sure we need to do some adjustments here. First, you have a good approach doing “family” rather than person, this compensates for larger Jewish families. Another question would be ages – if Jews have larger families, than maybe average age is lower and this greatly affects the income. Also – are these numbers before or after government transfers? This will affect all calculations.
also, you want to compare KJ with other similar areas, not parts of NYC.
