As marriage rates continue to decline – the number of 30-somethings who are married has decreased by 10 percent in the last decade, while the percentage of unmarried couples living together has risen from 7 to 13 percent – the traditional married couple household may not be as dominate as in the past. Moreover, the percentage of 18-29 year-olds who are single and living alone has risen from 52 percent in 2004 to 64 percent in 2014.

According to Gallup Analytics, fewer people are getting married and are staying single longer.

How this plays out in the years ahead in the U.S. housing market remains to be seen but change seems certain.
