The following section includes data on heroin-related arrests by the Philadelphia Police Department. Data was provided de-identified and includes information on arrest location, crime identification, and district codes. Arrests were pulled and classified based on the following Uniform Crime Reporting (UCR) arrest codes: 1805 (seller of heroin), 1815 (manufacture, delivery, or possession with intent to deliver), and 1825 (possession of heroin). Data shown is complete through June 30, 2018.

There are a few limitations to the dataset for arrests. First, true UCR arrests are enforcement driven and do not reflect the actual heroin market conditions. Second, because people may have been arrested multiple times during the specified time period, it is unlikely that the total number of arrests is higher than the data reflects.

This section also includes data from drug seizures that occurred in Philadelphia County and were analyzed and reported to the National Forensic Laboratory Information System (NFLIS). NFLIS is a system used by the Drug Enforcement Agency (DEA) that systematically collects results from laboratory drug analyses by federal, state, and local forensic laboratories across the country. The dataset displays additional drugs found in combination with heroin in the seizure analysis and drug types found in all drug seizures and are visualized as percentages of presence in the overall dataset.
