What follows is a description of the geography of capital punishment in the United States. The first section maps the distribution of death sentences from 2004 to 2009, identifying the most active jurisdictions (in absolute numbers) at both the state and county level. The second section details the distribution of executions. It has a dual focus - first on patterns that have emerged since 1976 and second on those that developed from 2004 to 2009. The third section considers those counties, which are situated in states that regularly execute offenders, that sentence people to death in comparatively large numbers. Part I of this Essay therefore identifies those counties that mark the center of gravity for death penalty activity in the United States.
