Neighbourhood income inequality and property crime
利用美国三个城市的人口普查区块组数据，研究发现邻里间的收入不平等会显著影响财产犯罪率：与更穷的区块组收入差距越大，较富裕区块组的财产犯罪越多，而最穷区块组的犯罪反而较少。
This paper examines the relationship between income inequality and property crime using Census block group data from three US cities: Nashville, TN, Portland, OR and Tucson, AZ. This paper is one of very few to examine this relationship at such a fine geographic level, which is typically less than one square mile in size. We find that income inequality across block groups plays a key role in determining the level of property crime. As the income gap with one’s poorest neighbouring block group widens, the level of property crime in the richer block group increases. Also, the poorest block group in an area tends to experience less property crime, holding all else constant.
