Social science research is increasingly considering place when examining social programs and policies with a spatial component. A specific research challenge involving spatial policies is how to select a sample of individuals based on their geographic locations. This article illustrates the use of geographic information systems, tax parcels, and mail surveys to target residents in varied geographic areas. A provided example demonstrates how researchers obtained a sample of respondents living within one tenth of a mile of multiple registered sex offenders. The challenges of using tax parcels to obtain addresses for apartments and mobile home parks are also explored.
在研究具有空间要素的社会项目和政策时，社会科学研究越来越多地考虑到地点因素。涉及空间政策的一个具体研究挑战是如何根据个体的地理位置来选取样本。本文阐述了如何利用地理信息系统、税 parcel（地块）和邮件调查来针对不同地理区域的居民。所提供的一个例子展示了研究人员如何获得居住在多名登记性犯罪者一英里范围内十分之一英里区域内的受访者样本。文中还探讨了利用税 parcel（地块）获取公寓和移动房屋公园地址时所面临的挑战。
