This essay reviews three books as they document and explain the 1990s crime decline: Alfred Blumstein and Joel Wallman, eds., (2006) The Crime Drop in America; Arthur S. Goldberger and Richard Rosenfeld, eds., (2008) Understanding Crime Patterns: Workshop Report; and Franklin E. Zimring (2007), The Great American Crime Decline.
It presents the empirical detail of the crime decline and examines the most commonly cited explanatory factors: imprisonment, policing, demography, and economic growth. It then suggests alternative lines of research in urban sociology—urban development, youth culture, and immigration—that may better explain the decline as the result of changes in the cultural and social fabric of American society, particularly in cities where the steepest declines occurred.
