(click on year to see the murder rates and calculations
involved in this analysis, provided by David Cooper)
* Includes Kansas and New York in the years
after they adopted the death penalty, 1994 and 1995 respectively.
New Jersey and New York ended the death penalty in the latter
part of 2007 and will not be counted as
death penalty states in 2008.
Notes:
Populations are from the U.S. Census estimates for each year.
Murder rates are from the FBI's "Crime in the United States"
and are per 100,000 population.
The murder rate for the region
(death penalty states or non-death penalty states)
is the total number of murders in the region
divided by the total population
(and then multiplied by 100,000)
In calculations that include Kansas and New York,
Kansas is counted as a death penalty state
from 1994 and New York from 1996,
since New York's law did not become
effective until September, 1995.
