title: GIS Shapefile - Crime Risk Database, MSA

description: Crime data assembled by census block group for the MSA from the Applied Geographic Solutions' (AGS) 1999 and 2005 'CrimeRisk' databases distributed by the Tetrad Computer Applications Inc.   CrimeRisk is the result of an extensive analysis of  FBI crime statistics. Based on detailed modeling of the relationships between crime and demographics, CrimeRisk provides an accurate view of the relative risk of specific crime types at the block group level.  Data from 1990 - 1996,1999, and 2004-2005 were used to compute the attributes, please refer to the 'Supplemental Information' section of the metadata for more details.  Attributes are available for two categories of crimes, personal crimes and property crimes, along with total and personal crime indices.  Attributes for personal crimes include murder, rape, robbery, and assault.  Attributes for property crimes include burglary, larceny, and mother vehicle theft.  12 block groups have no attribute information.  CrimeRisk is a block group and higher level geographic database consisting of a series of standardized indexes for a range of serious crimes against both persons and property. It is derived from an extensive analysis of several years of crime reports from the vast majority of law enforcement jurisdictions nationwide. The crimes included in the database are the "Part I" crimes and include murder, rape, robbery, assault, burglary, theft, and motor vehicle theft. These categories are the primary reporting categories used by the FBI in its Uniform Crime Report (UCR), with the exception of Arson, for which data is very inconsistently reported at the jurisdictional level. Part II crimes are not reported in the detail databases and are generally available only for selected areas or at high levels of geography.  In accordance with the reporting procedures using in the UCR reports, aggregate indexes have been prepared for personal and property crimes separately, as well as a total index. While this provides a useful measure of the relative "overall" crime rate in an area, it must be recognized that these are unweighted indexes, in that a murder is weighted no more heavily than a purse snatching in the computation. For this reason, caution is advised when using any of the aggregate index values.  The block group boundaries used in the dataset come from TeleAtlas's (formerly GDT) Dynamap data, and are consistent with all other block group boundaries in the BES geodatabase.
      
      
          This is part of a collection of 221 Baltimore Ecosystem Study metadata records that point to a geodatabase.
      
      
          The geodatabase is available online and is considerably large.  Upon request, and under certain arrangements, it can be shipped on media, such as a usb hard drive.
      
      
          The geodatabase is roughly 51.4 Gb in size, consisting of 4,914 files in 160 folders.
      
      
          Although this metadata record and the others like it are not rich with attributes, it is nonetheless made available because the data that it represents could be indeed useful.
