The purpose of the study was to examine how court decisions and sentencing policy changes have affected sentencing behavior in federal drug trafficking cases. Changes at the district level and in mandatory minimum sentencing were a particular focus.

Data were obtained from the Defendants Sentenced Under the Sentencing Reform Act data from the United States Sentencing Commission from fiscal years 1992-2009. These data were then merged with federal district-level indicators for the 89 federal districts from the Federal Court Management Statistics website, and state level demographic data from the United States Census Bureau. Drug trafficking cases were identified by using the sentencing guideline offense, which resulted in a sample of N=376,637 cases.

The purpose of the study was to examine how court decisions and sentencing policy changes have affected sentencing behavior in federal drug trafficking cases. Changes at the district level and in mandatory minimum sentencing were a particular focus.

Data were obtained from the Defendants Sentenced Under the Sentencing Reform Act data from the United States Sentencing Commission from fiscal years 1992-2009, which contained all offenders in federal court in those fiscal years. These data were then merged with federal district-level indicators for the 89 federal districts from the Federal Court Management Statistics website, state level demographic data from the United States Census Bureau, Uniform Crime Reporting (UCR) data collected by the Federal Bureau, and the Treatment Episode Data Set (TEDS) maintained by the Substance Abuse and Mental Health Services Administration (SAMHSA). Drug trafficking cases were identified by using the sentencing guideline offense, which resulted in a final sample of N=376,637 cases.

The initial sample included 1,042,207 cases. Drug trafficking cases were identified by using the sentencing guideline offense, which resulted in a sample of N=376,637 cases. The sample does not include cases from 1992 and cases from United States territories.
