National statistics from Federal agencies and a limited number of studies do not support the perception by the public, the media, and government officials that crimes within and against businesses are infrequent and that small businesses do not represent a large segment or vital component of society or the economy. The survey of businesses in Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin took place in the spring of 1996. Results revealed that crime directly affected 1 in 8 small businesses in a 1-year period. Burglary and vandalism were the most common crimes. Repeat and multiple victimizations were also common. Moreover, crime patterns were not random. Nevertheless, just under half the proprietors engaged in crime prevention measures, usually only one measure. The financial losses due to burglary, theft, or property damage were significant but generally not devastating costs to the businesses. In addition, few businesses identified increased personnel or management costs that they could attribute to crime. Further research should include national studies and further breakdowns by location, size, and business sector. Tables and 81 reference notes (Author abstract modified)
