Fix your second link. It is busted.

Neat! Keister is a blockhead, but as you say some of the data is interesting. This caught my eye:

Jewish people stood out in a third trajectory in which people invest early in life in high-risk, high-return assets such as stocks and bonds and build wealth quickly while putting less emphasis on homeownership. About one-third of Jews followed this path, compared to no conservative Protestants, 7 percent of mainline Protestants and 4 percent of Catholics.

Now, describing bonds as high-risk, high-return is stupid. But the interesting thing to me is that this is the sort of thing you might expect from a people who have historically been merchants and traders: less emphasis on land (home) ownership, more on building portable wealth.

also, many jews live in urban areas where buying a house when you're young is kind of difficult since they are so pricey.... (i suspect north dakota lutherans have high home ownership rates)

True. In fact now that I think about it the jewish population of NYC alone probably accounts for a significant portion of the variation.
