If y'all's family moves during y'all's school years (ages 6-15), y'all's chance of graduating high school falls by 16 percent, the chance that you'll be economically inactive (out of school and out of work) at age 24 rises by 10 percent--and, if you are female, y'all's chance of getting through y'all's teens without an out-of-wedlock birth falls by 6 percent.
The chance drops even more if y'all's parents are divorced.
