(FL,IL,CA,OH). All have Jewish concentrations.
i'm not getting involved in the content of this thread but wanted to explain some population numbers.
not nearly as concentrated as NY/NJ. Based of a stint publishing and delivering a weekly in the Kensington neighborhood of Brooklyn these are my anecdotal numbers. One city block often had 200 families, all Orthodox, about 4500 households in a relatively small area of Brooklyn- Other publications claimed that Boro Park had 40000 orthodox households. That doesn't include Crown Heights, Midwood, Williamsburg, and the dozen other small orthodox neighborhoods.
Compared to the block I grew up on in Chicago which had about 40 families total and only 8 Jewish families. Recently I was working on some community info in Boston and a colleague in Chicago who had worked on a similar project claimed the total number of orthodox households to be in the 3000 - 3500 range.
Again, anecdotal, but a huge disparity nonetheless.
The numbers are genuinely crazy...
