“the TOTAL population of Lakewood Township in 2010 was 92,843”
I’m pretty sure that at some point between 2011-2015, I heard (from more than one source,) that there were approximately 12,000 Jewish families in Lakewood comprising approximately 50,000 people. I also heard (at around the same time) that the Jewish population was approximately 60%. So that fits in with your figure.
However, it doesn’t necessarily contradict Joseph’s figure since there has been a very rapid population growth (although I don’t know the numbers).
“Given the size of frum families, your family numbers appear to be high”
You have to keep in mind that a large percentage of the population is comprised of newly married couples who don’t have children yet as well as young couples who only have one or two children. These are probably the people who account for a big part of the population growth (which would mean that the number of families has probably increased at a higher rate than the number of people, I think).
