- 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

based on estimates rather than reported data. The coverage indicator
(CI) for each county is calculated as follows:

-
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?
- How well have the observations been checked?
- How accurate are the geographic locations?
- How accurate are the heights or depths?
- 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.
- 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.
