In short, that 26-year-old college graduate living in your basement doesn't have any money to buy houses. And that's obviously not a good thing for the ready mixed concrete industry. A May 14 article posted on Yahoo.com discusses this issue, stating that the financial picture for millennials is improving, but the housing market is getting impatient. The article cites a research report from a few months back indicated that joblessness, stagnant income and student loan debt had not only set millennials back, but kept enough of them away from buying homes to account for 3 million homes' worth of property demand. According to the Census Bureau, 30.3% of millennials ages 18 to 34 still live at home with their parents.
