The comparison of household income of Teaneck vs. Lakewood is highly flawed.
CS made the valid point that the Lakewood firm community has spIlled over into adjacent townships.
There are other flaws in the comparison, though, as well.
What are the average ages of the heads of household? I would think Lakewood’s would be younger because of the constant influx from BMG bochurim who get married. Obviously, the longer people are in the workforce, the more they typically earn, so without these numbers, the comparison is unfair.
Even more important is that Lakewood has a large population of non Jewish low income families, which (correct me if I’m wrong) isn’t the case in Teaneck.
For the purpose of this discussion, one would need to compare frum families. Are there any statistics on that?
