Chapter III - SUMMARY OF STUDIES In an effort to prove or dispel the perceptions that adult entertainment affects other uses in their neighborhoods, several cities have conducted studies of areas which presently contain adult businesses. These studies concentrated on changes in property values and crime rates as a base upon which to measure both the direct and indirect impacts of the neighborhood. The study parameters established a "Control Area" and a "Study Area". The Study Areas chosen were areas which were generally adjacent to residential areas, contained land zoned commercial and contained at least one adult entertainment business. Control Areas were then selected which had characteristics similar to the Study Areas. The Control Areas were also zoned commercially and were adjacent to residential areas but contained no adult entertainment business. In a further effort to make the areas as similar as possible, the Control Areas ' that were selected had a demographic similarity to the Study Area and contained buildings d;ngs of a similar age and value as those in the Study Areas. The importance of selecting areas with characteristics as similar as possible was to enable a realistic comparison of what is happening in both areas. If we make the assumption that adult entertainment uses have no effect on adjacent neighborhoods then the trends in property values and crime statistics should be similar in both areas. 111/ Ay of the delete reports is attached far your review. A. Iniianarolis, Indiana In 1983 the Indianapolis Division of Planning undertook a study to dete.mine what effect adult entertainment uses were having on crime rates and property values where they were located. The study purpose was to consider the effect of adult'entertairmse.^.t by the analysis of: 1. crime reports provided by the Indianapolis Police Department (IPD) 2. the analysis of data reflecting the value of residential properties within 1000 feet of adult entertainment uses, and 3. the results of a random, national survey of the membership of the American Institute of Real Estate Appraisers. 1. Crime incidence: a) The average major crime rate (i.e. crises per 10,000 population) was 748.55 in the IPD District, 886.34 in the Control Area, 1090.51 in the Study Area. In areas of the study that contained at least one adult entertainment establishment major crimes occurred at a rate that was 23% higher than the six Control Areas studied not having such businesses and 46% higher than the Police District at large. • b) Although it was impossible to obtain a discrete rate for sex-related crimes at the police district level, it was possible to compare rates between the -Control Area and the Study Area. The average sex-related
