Within-family differences in life outcomes Bill Clinton is shown, at age 46, receiving the oath of office as the 42nd President of the United States. His half-brother Roger Clinton, at age 44, is shown in a police booking, after being charged with drunk driving—an incident that occurred about a month after Roger was granted a presidential pardon erasing an earlier cocaine-related offense for which he had spent a year in jail. The Clinton family illustrates the large differences in developmental outcomes that can occur within families.
