Census of Population, 2010: Summary File 1 (SF1) Download Center

Summary File 1 (SF 1) contains the data compiled from the questions asked of all people and about every housing unit. Population items include sex, age, race, Hispanic or Latino origin, household relationship, household type, household size, family type, family size, and group quarters. Housing items include occupancy status, vacancy status, and tenure (whether a housing unit is owner-occupied or renter-occupied). There are 177 population tables (identified with a ‘‘P’’) and 58 housing tables (identified with an ‘‘H’’) shown down to the block level; 82 population tables (identified with a ‘‘PCT’’) and 4 housing tables (identified with an “HCT”) shown down to the census tract level; and 10 population tables (identified with a “PCO”) shown down to the county level, for a total of 331 tables. The SF 1 Urban/Rural Update added 2 PCT tables, increasing the total number to 333 tables. There are 14 population tables and 4 housing tables shown down to the block level and 5 population tables shown down to the census tract level that are repeated by the major race and Hispanic or Latino groups. SF 1 includes population and housing characteristics for the total population, population totals for an extensive list of race (American Indian and Alaska Native tribes, Asian, and Native Hawaiian and Other Pacific Islander) and Hispanic or Latino groups, and population and housing characteristics for a limited list of race and Hispanic or Latino groups. Population and housing items may be cross-tabulated. Selected aggregates and medians also are provided. Summary File 1 (SF 1) is released as individual files for each of the 50 states, the District of Columbia, and Puerto Rico, and for the United States. The tables (matrices) are identical for all files, but the geographic coverage differs. SF 1 for states was released from June–August 2011. The national update file, without urban and rural components, was released in October 2011. The Urban/Rural Update of SF 1 also was released as individual files for the 50 states, the District of Columbia, Puerto Rico, and for the United States in September 2012.

摘要文件1（Summary File 1，简称SF 1）收录了针对全体人口及所有住房单元的调查汇总数据。人口统计项目涵盖性别、年龄、种族、西班牙裔或拉丁裔族源、住户内成员关系、住户类型、住户规模、家庭类型、家庭规模以及集体住户。住房统计项目涵盖居住状态、空置状态以及住房保有状态（即住房单元为自有自住还是租赁租住）。
本次数据集包含177张人口统计表（以字母"P"标识）与58张住房统计表（以字母"H"标识），统计精度可达街区级；82张人口统计表（以"PCT"标识）与4张住房统计表（以"HCT"标识），统计精度可达普查片区级；另有10张人口统计表（以"PCO"标识），统计精度可达县级，总计331张统计表。SF 1城乡更新模块新增2张PCT统计表，使总表数量增至333张。其中，14张人口统计表、4张住房统计表以及5张人口统计表按主要种族及西班牙裔或拉丁裔族群进行细分，统计精度覆盖街区级与普查片区级。
SF 1涵盖全体人口的人口与住房特征、覆盖范围广泛的种族族群（含美洲印第安人与阿拉斯加原住民、亚裔、夏威夷原住民及其他太平洋岛民）与西班牙裔或拉丁裔族群的人口总量，以及范围相对有限的种族与西班牙裔或拉丁裔族群的人口与住房特征。人口与住房统计项目支持交叉制表分析，同时提供部分汇总统计量与中位数。
摘要文件1（SF 1）以独立文件形式发布，覆盖美国50个州、哥伦比亚特区、波多黎各自治邦以及全美整体。所有文件的统计表（矩阵）结构完全一致，但地理覆盖范围存在差异。各州的SF 1数据集于2011年6月至8月间发布。不含城乡分类组件的全国更新文件于2011年10月发布。SF 1城乡更新模块同样以独立文件形式，于2012年9月面向50个州、哥伦比亚特区、波多黎各自治邦及全美整体发布。
