Registered Sex Offenders and Reported Sex Offenses
Author's manuscript made available in accordance with the publisher's policy.Geographic restrictions on registered sex offenders (RSOs) have become commonplace. Such policies generally assume that sex offenses are likely to be higher near RSOs. Yet, few ecological studies have examined this question empirically. The current study examines whether incidences of reported sex offenses are higher in proximity to the addresses of RSOs. Specifically, we examine whether there is a relationship between the number of reported sex offenses and the number of RSOs living in square grid cells (and in 1,000, 1,500, and 2,500 ft radii of the cell centroid) in Indianapolis. Count models indicate that the number of RSOs in an area is not a robust predictor of reported sex offenses, net of controls
The Implicit Price of Urban Public Parks and Greenways: A Spatial-Contextual Approach
This is an Author's Original Manuscript of an article submitted for consideration in the Journal of Environmental Planning and Management [copyright Taylor & Francis]; Journal of Environmental Planning and Management is available online at http://www.tandfonline.com/This paper examines the value residents place on public parks in a mid-sized urban area. The analysis makes a direct contribution to the literature by examining the extent to which spatial and neighborhood context is related to the house price premium or discount associated with public recreational opportunities, natural resource areas, and urban greenways. The analysis shows that the value of public parks and greenways varies across space, neighborhood context, and park type. Community area fixed-effects are included to bolster the findings. The findings indicate that park and greenway investment should be planned and managed contextually in urban areas. Park planners can use these findings to inform public policy debates over park investment and, perhaps, support efforts focused on comprehensive neighborhood planning
Land Use And Violent Crime
Author's manuscript made available in accordance with the publisher's policy.Although research has shown specific land uses to be related to crime, systematic investigation of land uses and violent crime has been less common. This study systematically examines links between land uses and violent crime and assesses whether such links are conditioned by socioeconomic disadvantage. We employ geocoded Uniform Crime Report (UCR) data from the Indianapolis police department and information on 30 categories of land use and demographic information from the 2000 U.S. Census. We use land use variables to predict violent crime counts in 1,000 Γ 1,000-feet grid cells using negative binomial regression models. Results indicate that, net of other variables, specific land uses predict variation in counts for individual violent crimes and aggregate rates. Some nonresidential land uses are associated with higher violent crime counts, whereas others are associated with lower counts. Specific land uses also condition the effects of socioeconomic disadvantage on violent crime. The implications for routine activity/opportunity and social disorganization/collective efficacy theories of crime are discussed
Studying the Child Obesity Epidemic with Natural Experiments
We utilize clinical records of successive visits by children to pediatric clinics in Indianapolis to estimate the effects on their body mass of environmental changes near their homes. We compare results for fixed-residence children with those for cross-sectional data. Our environmental factors are fast food restaurants, supermarkets, parks, trails, and violent crimes, and 13 types of recreational amenities derived from the interpretation of annual aerial photographs. We looked for responses to these factors changing within buffers of 0.1, 0.25, 0.5, and 1 mile. We found that cross-sectional estimates are quite different from the Fixed Effects estimates of the impacts of amenities locating near a child. In cross section nearby fast food restaurants were associated with higher BMI and supermarkets with lower BMI. These results were reversed in the FE estimates. The recreational amenities that appear to lower children's BMI were fitness areas, kickball diamonds, and volleyball courts. We estimated that locating these amenities near their homes could reduce the weight of an overweight eight-year old boy by 3 to 6 pounds
The Effect of Foreclosures on Crime in Indianapolis, 2003-2008
Author's manuscript made available in accordance with the publisher's policy.Objective
Until recently, few studies have examined the relationship between home foreclosures and crime. Foreclosures are one major source of neighborhood instability and can be expected to affect crime from several theoretical perspectives. Some recent research has found conflicting results on whether foreclosures cause crime.
Method
This study examines whether foreclosures are a robust predictor of crime and whether the effect of foreclosures on crime varies across neighborhood contexts. We estimate fixed-effects negative binomial models using geocoded Indianapolis foreclosure and crime data for 2003β2008 to predict crime counts in 1,000 feet Γ 1,000 feet square grid cells.
Result
Foreclosures exhibit consistent positive effects on indices of overall, property, and violent UCR-reported (where UCR is Uniform Crime Report) offenses in a cell and rape, aggravated assault, and burglary counts. In addition, foreclosures had greater effects on reported UCR crimes in stable neighborhoods, especially those with more owner-occupied homes.
Conclusion
Foreclosures were a robust predictor of crime in the current study
The Spatial Extent of the Effect of Foreclosures on Crime
Author's manuscript made available in accordance with the publisher's policy.Although neighborhood stability has long been considered a substantial determinant of crime, foreclosures have not been the subject of concerted research among criminologists until recently. A number of recent studies have examined the linkage between home foreclosures and crime. Though generally finding a significant relationship, studies have used different approaches and units of analysis. This variation led us to examine the spatial extent to which foreclosures affect a relatively small surrounding area. In this paper, we consider the spatial extent of the foreclosure effect on crime by estimating fixed effect negative binomial models using geocoded UCR data for 2003β2008 and foreclosure data to predict crime counts using the number of foreclosures within various small area radii. Results show that, independently and jointly, foreclosures are a predictor of crime up to at least a distance of 2250 feet. Importantly, that effect declines with distance. We conclude with a discussion of the implications of those findings
Intra and Inter-Neighborhood Income Inequality and Crime
Author's manuscript made available in accordance with the publisher's policy.One important factor in many macro-level theories of crime is income inequality. Although research generally shows that low levels of neighborhood income are associated with crime, research studies have been less clear on whether income inequality is a robust, independent predictor of crime, particularly in small area studies, and few studies have explicitly considered income inequality between neighborhoods, and those that do typically focus on homicide. The current study examines whether within and between neighborhood income inequality is associated with variation in violent and property crime. We employ geocoded Uniform Crime Report data from the Indianapolis police department and economic and demographic characteristics of the population from the American Community Survey for 2005β2009. Consistent with prior research, lower levels of income were associated with higher violent and property crime counts. Within-tract income inequality was also associated with higher Uniform Crime Reports violent and property crimes in most models. Results also showed that the ratio of tract income levels to neighboring tracts is associated with variation in crime. Thus, both local and nearby income inequality affect crime. Implications for theory and policy are discussed
