In com­mem­o­ra­tion of the 20th anniver­sary of the U.S. Supreme Court’s land­mark deci­sion end­ing the juve­nile death penal­ty, the Death Penalty Information Center (DPI) has released a new report: Immature Minds in a Maturing Society”: Roper v. Simmons at 20, detail­ing the grow­ing sup­port for the idea that indi­vid­u­als ages 1819, and 20 should receive the same age-appro­pri­ate con­sid­er­a­tions that juve­niles now receive in death penal­ty cas­es. The report also reveals trou­bling new data about racial dis­par­i­ties with­in this age group. 

According to a new DPI analy­sis, more than three-quar­ters (78%) of all death sen­tences imposed dur­ing the last twen­ty years on indi­vid­u­als age 18, 19, or 20 have been imposed on peo­ple of col­or. This is well above the rate found in old­er defen­dants: by com­par­i­son, fifty-sev­en per­cent of the death sen­tences imposed dur­ing this same time frame on adults 21 and old­er were imposed on peo­ple of color. 

Emerging adults dis­pro­por­tion­ate­ly com­prise those who are arrest­ed and incar­cer­at­ed across the coun­try … in a crim­i­nal jus­tice sys­tem rife with racism, avail­able data sug­gests racial dis­par­i­ties are worst for this age group. 

Nearly all juris­dic­tions that have sen­tenced peo­ple under 21 to death since Roper have sen­tenced young peo­ple of col­or, and par­tic­u­lar­ly young Black peo­ple, at dis­pro­por­tion­ate rates. In eighty-sev­en per­cent of juris­dic­tions that sen­tenced any­one in this age group to death since Roper, half or more were peo­ple of col­or. In sev­en­ty-three per­cent of the juris­dic­tions that sen­tenced any 18- to 20-year-old to death since Roper, half or more were Black peo­ple. In some states this trend is even more pro­nounced: in California, in the twen­ty years since Roper, nine out of ten death sen­tences giv­en to emerg­ing adults at the time of their crime were imposed on peo­ple of col­or. For com­par­i­son, rough­ly three-quar­ters of all death sen­tences imposed in the state dur­ing this time­frame were imposed on peo­ple of color. 

Studies sug­gest that Black youth are held to dif­fer­ent stan­dards and judged more harsh­ly than their white peers when it con­cerns guilt and pun­ish­ment. They are more like­ly to be per­ceived as old­er than their actu­al age; as less inno­cent; and as more angry — all of which can lead to harsher punishments. 

The new DPI analy­sis also shows how age and race affect out­comes in unex­pect­ed ways. The aver­age age at crime for peo­ple sen­tenced to death is 34.3 years old for white peo­ple and 29.7 years old for peo­ple of col­or, a near­ly five-year gap. In some states, the gap is as large as 15 years. 

Once sen­tenced to death, emerg­ing adults of col­or also face a high­er chance of being exe­cut­ed. Since Roper, peo­ple of col­or who have been sen­tenced to death for crimes com­mit­ted as emerg­ing adults are almost twice as like­ly as white emerg­ing adults to be exe­cut­ed. Texas alone accounts for half of all emerg­ing adult exe­cu­tions since Roper. Almost eighty per­cent of the emerg­ing adult cohort mem­bers exe­cut­ed in Texas dur­ing this time­frame were peo­ple of color.
