title: Uniform Crime Reporting Program Data: Offenses Known and Clearances by Arrest, 1960-2016

description: <b>V4 release notes: </b><br>Merges data with LEAIC data to add FIPS codes, census codes, agency type variables, and ORI9 variable.<br>Makes all column names lowercase.Change some variable names<br>Makes values in character columns lowercase.<br>Adds months_reported variable to yearly data.Combines monthly and yearly files into a single zip file (per data type).<br><b>V3 release notes:</b><br> fixes a bug in Version 2 where 1993 data did not properly deal with missing values, leading to enormous counts of crime being reported. <br>This is a collection of Offenses Known and Clearances By Arrest data from 1960 to 2016. Each zip file contains monthly and yearly data files. The monthly files contain one data file per year (57 total, 1960-2016) as well as a codebook for each year. These files have been read into R using the ASCII and setup files from ICPSR (or from the FBI for 2016 data) using the package asciiSetupReader. The end of the zip folder's name says what data type (R, SPSS, SAS, Microsoft Excel CSV, Stata) the data is in. <br><br>The files are lightly cleaned. What this means specifically is that column names and value labels are standardized. In the original data column names were different between years (e.g. the December burglaries cleared column is "DEC_TOT_CLR_BRGLRY_TOT" in 1975 and "DEC_TOT_CLR_BURG_TOTAL" in 1977). The data here have standardized columns so you can compare between years and combine years together. The same thing is done for values inside of columns. For example, the state column gave state names in some years, abbreviations in others. For the code uses to clean and read the data, please see my GitHub file here. https://github.com/jacobkap/crime_data/blob/master/R_code/offenses_known.R<br><br>The yearly data set is a single file with all years stacked together. It also contain far fewer descriptive columns about the agencies in an attempt to decrease file size. The data file is aggregated yearly and has already combined every year 1960-2016. For the code I used to do this, see here https://github.com/jacobkap/crime_data/blob/master/R_code/yearly_offenses_known.R.<br><br>If you find any mistakes in the data or have any suggestions, please email me at jkkaplan6@gmail.com<br><br>As a description of what UCR Offenses Known and Clearances By Arrest data contains, the following is copied from ICPSR's 2015 page for the data.<br><br>The Uniform Crime Reporting Program Data: Offenses Known and Clearances By Arrest dataset is a compilation of offenses reported to law enforcement agencies in the United States. Due to the vast number of categories of crime committed in the United States, the FBI has limited the type of crimes included in this compilation to those crimes which people are most likely to report to police and those crimes which occur frequently enough to be analyzed across time. Crimes included are criminal homicide, forcible rape, robbery, aggravated assault, burglary, larceny-theft, and motor vehicle theft. Much information about these crimes is provided in this dataset. The number of times an offense has been reported, the number of reported offenses that have been cleared by arrests, and the number of cleared offenses which involved offenders under the age of 18 are the major items of information collected.<br><br><br><br>
