Still other theories attempt to explain differences
in crime patterns at much higher
levels of aggregation. For example, theories
of crime differ among cities and
among regions. On the city level, suggested
actions may include citywide changes
in economic, transportation, education,
welfare, and recreation policies, to name a
few. On the multijurisdictional or multistate
regional levels, suggested actions
against concentrations of crime could
include even broader scale policies or
social change. Although these are interesting
theories, they are far less useful for
local police agencies. Thus, they are not
examined here.
