NEW: Death Row Inmates, 1953-2009. In 1953, death row had 131 inmates, and 62 of them (47.33%) were executed. In 2009, death row had grown to 3,173 inmates (a 2,322% increase), and 52 of them (1.64%) were executed. The average time on death row more than doubled from 6 years and 2 months in 1984 to 14 years and one month by 2009. The primary reason inmates no longer serve on death row is not because of execution (24.0%) but because their sentence or conviction was overturned (59.5%). Our new charts detail the number of death row inmates, executions, and average time in prison, as well as the primary reasons for removal from death row.
