What does this data set describe?

Title: United States Crimes Database 2001-2002
Abstract:
This map layer shows crime statistics for the United States for the years 2001-2002, drawn from the Uniform Crime Reporting Program data compiled by the Federal Bureau of Investigation and archived at the Inter-university Consortium for Political and Social Research (ICPSR). Crime data are reported by county and are provided for eight crimes: murder, forcible rape, robbery, aggravated assault, burglary, larceny, motor vehicle theft, and arson. Statewide allocation data are not included in this map layer. Crime data are adjusted to compensate for incomplete reporting by individual law enforcement agencies. See the online codebook at <http://www.icpsr.umich.edu/cgi>- bin/bob/archive2?study=4009&path=NACJD&docsonly=yes> for more information.
Supplemental_Information:
Some of the crime data reported in this file was estimated. Where agencies reported for 12 months, the data were included as reported. Where agencies reported for between three and eleven months, the data were increased by a weight of (12/months reported). Where agencies reported for one or two months, the actual data were not included, but estimated data for the entire year were calculated based on rates computed using data from 12-month reporting agencies within the same geographic stratum (defined by population group) within that State. Where agencies did not report at all, no estimations were performed. For New York City in 2001, the total number of murders in the FBI data files is 3,452, which includes 2,823 victims of the September 11 bombing. For more information on imputation procedures please see <http://www.icpsr.umich.edu/cgi-bin/bob/archive2?study=4009&path=NACJD&docsonly=yes> to access the Codebook for ICPSR Study Number 4009.

    CI = (1-(sum((agency pop/pop_arr01)((12-months reported)/12))))*100
    
    Where agency pop is the population represented by the reporting agency, and pop_arr01 is the total population for the county (as defined above). The value for "months reported" will be 0 for agencies reporting 1-2 months of data, because any data provided by these agencies was set to zero and the data were estimated using the procedure described above.

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)

    • National Atlas of the United States

  2. Who also contributed to the data set?

  3. To whom should users address questions about the data?

Why was the data set created?

These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the Department of Justice, the National Atlas of the United States, or the ICPSR in the use of these data.

  2. How were the data generated, processed, and modified?

    Date: Apr-2005 (process 1 of 2)
    Comma-delimited text files for individual years, containing selected attributes, were received from the Bureau of Justice Statistics data archive (ICPSR) at the University of Michigan. The text files were loaded into Access and output in dBASE V format, then loaded into ArcMap for processing. State and County FIPS code fields were combined into one FIPS field and were converted to text. Attribute names were modified to conform to the attribute names from previous years. The FIPS code for Dade County, FL was changed to match the new FIPS code for Miami-Dade County, FL. The dBASE files did not contain records for Denali, Alaska, so one was added to each file with all values set to zero.

    The county boundaries file was loaded into ArcMAP, joined to the dBASE V crime files, and the result was exported to a new shapefile.

    A query was run on the shapefile to select records for each year where the coverage index for that year was greater than zero and the crime population for the same year was zero, resulting in about 20 selections for each year. Where the selected records included crime statistics for a particular year, the arrest population value for that year was substituted for the zero value in the crime population field. If the selected records included no crime statistics for a particular year, the coverage index was reset to zero. New fields were added for crime normalized by population. Queries were run for each year to detect records with missing data (coverage index was zero, crime population was zero, and all crime statistics were zero.) The new fields were populated with the value -9999 for records with no data available (referred to as missing data by NACJD). For records with data, the values for the new fields were calculated by dividing the crime population for a particular year into the crime statistic for that year and then multiplying the result by 100.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    This map layer includes crime statistics for the 50 United States as collected by the Federal Bureau of Investigation, from reports submitted by agencies and States participating in the Uniform Crime Reporting Program. This is a voluntary program so the data may not include reports from all law enforcement agencies. Data collected for a State but not attributable to a specific county (Statewide allocations) are not included. Limited offense data were available for Kentucky, Mississippi, Montana, and South Dakota.

  5. How consistent are the relationships among the observations, including topology?

    No checks for logical consistency were performed on this map layer. For information on data imputation procedures used in areas where reporting was less than 100 percent, please see <http://www.icpsr.umich.edu/cgi-bin/bob/archive2?study=4009&path=NACJD&docsonly=yes> to access the Codebook for ICPSR Study Number 4009.
