"The most obvious trend is that higher a person's income, the less a proportion of their wealth is tied up into their homes. People in the bottom three income quintiles had roughly half their total wealth embedded into their principal residences, and another 8-9 percent in other forms of real estate. By contrast, the top 10 percent of earners had just 21 percent of their assets in their residences, and another 13 percent in other categories of real estate (including second homes)." - Steven Perez from Bookmarklet
