Data Source and Methods The national arrest estimates presented here (as well as the per capita rates based upon those estimates) were calculated by the Justice Research and Evaluation Center at John Jay College of Criminal Justice using data released in 2010 by the Uniform Crime Reporting Program (UCR) of the Federal Bureau of Investigation (FBI). The FBI collects annual information on arrests made by law enforcement agencies throughout the United States. Data are collected from jurisdictions containing a majority of the U. S. population, typically between 70 and 80 percent of residents nationwide. The primary publication of UCR data, Crime in the United States, is based upon data from those police agencies able to participate fully in the UCR program each year. Full participation requires that agencies submit their data to the FBI on time and their data must cover all arrests for a minimum number of months during the year. For 2009, the jurisdictions that participated fully in the UCR program represented 78 percent of the national population. Nearly all of the arrest statistics generated by the FBI are based on this sample. The FBI calculates just one national estimate for each major offense. It does not calculate national estimates for different age groups. To present national arrest estimates for various groups and to calculate per capita arrest rates for those groups, this presentation relies on the FBI’s estimate of total arrests for each major offense. It uses the data reported by UCR-participating jurisdictions to determine the proportion of arrests for each offense that involved individuals of various ages. That proportion is then applied to the FBI’s national estimate for each offense. Arrest rates are determined by dividing each national arrest estimate over the appropriate population data from the U. S. Bureau of the Census. These estimation procedures were first developed by Dr. Howard Snyder, now with the Bureau of Justice Statistics at the U. S. Department of Justice.

Summary of National Trends • Juvenile arrest rates are trending downward, according to the

Summary of National Trends • Juvenile arrest rates are trending downward, according to the most recent national data. • After the historic decline in violent crime from 1995 through 2004, arrest rates in some offenses grew slightly for one or two years. • Juvenile arrest rates then generally began to fall again after 2006. • When all four offenses in the Violent Crime Index are considered together, arrest rates in 2009 were at their lowest point since 1980. • The small increase in juvenile murder arrests after 2004 appears to have stopped and murder arrests now appear to be stabilizing. • The juvenile arrest rate for robbery grew sharply from 2004 to 2006, but it too may have begun to stabilize, although at a level still higher than the historic lows reached during the early 2000 s. • The rate of juvenile arrests for aggravated assault continued its 15 -year decline, reaching a level not been since the mid 1980 s. • The juvenile arrest rate for weapon offenses also fell between 2006 and 2009, reaching the previous low point of 2002.
