This works because it combines two independent variables by multiplying them together, making the situation look even worse.

Another important point – in 1950, almost 80% of adults in the U.S. were married; today it is just under 50%. Thus, there are simply fewer married people overall than there were in the past – this has nothing to do with housing. What happened? One, more couple living together without being married, an increase in childless couples (who did not then see a reason to marry), and single parent households.

Furthermore, during this time period the average home size nearly tripled in size – think that has an effect on prices?

The effect is that the above claims about being married and owning a home are largely meaningless.
