This data set contains household survey data from Census. The American Community Survey was developed by the Census Bureau to replace the long form of the decennial census program. The ACS is a large demographic survey collected throughout the year using mailed questionnaires, telephone interviews, and visits from Census Bureau field representatives to about 3.5 million household addresses annually. Starting in 2005, the ACS produced social, housing, and economic characteristic data for demographic groups in areas with populations of 65,000 or more. (Prior to 2005, the estimates were produced for areas with 250,000 or more population.) The ACS also accumulates sample over 3-year and 5-year intervals to produce estimates for smaller geographic areas, including census tracts and block groups.

本数据集收录了来自人口普查的住户调查数据。美国社区调查（American Community Survey，简称ACS）由人口普查局开发，旨在替代十年一度人口普查计划的长期问卷。ACS是一项大型的年度人口普查调查，通过邮寄问卷、电话访谈以及人口普查局现场代表访问约350万户家庭地址的方式进行收集。自2005年起，ACS开始为人口超过65,000的地区的各类人口群体提供社会、住房和经济特征数据。（2005年之前，估计数据是为人口超过250,000的地区提供的。）此外，ACS还累积3年和5年的样本数据，以生成针对较小地理区域的估计，包括人口普查区和街区组。
