The Statistical Abstract of the United States, published since 1878, is the authoritative and comprehensive summary of statistics on the social, political, and economic organization of the United States. Access by year makes targeted historical research especially easy. Free access provided by the United States Census Bureau ended in 2012.
Based on the data in Statistical Data Sets, this interface does not require Java to run. You can choose a subject category, e.g., criminal justice and law enforcement, and search for a keyword, e.g., drug, and find statistics in that area.
The Bureau of Justice Statistics collects, analyzes, publishes, and disseminates information on crime, criminal offenders, victims of crime, and the operation of justice systems at all levels of government.
