In 2000, a full 26 percent of Gen-Xers -- then at the same age range -- had reported making a move in the previous year. In 1963, members of the Silent Generation moved at a 26 percent rate, too. The census data being used here doesn't include college-dorm moves prevalent with 18- to 24-year-olds, so those young'uns are left out of the analysis. The 20 percent rate is the lowest level of young adult mobility in half a century, Fry reports, and all this with millennials getting married, owning homes, and having kids less than previous generations. Student debt and less favorable lending rates may be driving down homeownership -- imagine that -- which further reduces movement. Psychologically, this also means that young adults are more stuck with their personalities and faded of memory compared with their more mobile peers.
