This chapter takes as its organizing theme what we know – and do not know –
about macro-social trends in crime. Following a brief description of crime trends in
comparative perspective, the chapter reviews research on the factors associated with its
rise and decline. The discussion is organized in six categories: demography and
economic conditions; policing and incarceration; drugs, guns and gangs; community
and environmental factors; lifestyle and culture; and crime reporting and recording. The
goal of this review is to provide an entry point into the literature on crime trends, point out
what is known and what needs to be known about why crime goes up and down, and
highlight some of the issues facing those who take up the challenge. Although much of
the research is North American in orientation, the factors associated with crime and the
technical issues involved in addressing their impact are of broad cross-national
significance.
