Population and Housing Census 2007 - IPUMS Subset - Ethiopia

Abstract
---------------------------

IPUMS-International is an effort to inventory, preserve, harmonize, and disseminate census microdata from around the world. The project has collected the world's largest archive of publicly available census samples. The data are coded and documented consistently across countries and over time to facillitate comparative research. IPUMS-International makes these data available to qualified researchers free of charge through a web dissemination system.

The IPUMS project is a collaboration of the Minnesota Population Center, National Statistical Offices, and international data archives. Major funding is provided by the U.S. National Science Foundation and the Demographic and Behavioral Sciences Branch of the National Institute of Child Health and Human Development. Additional support is provided by the University of Minnesota Office of the Vice President for Research, the Minnesota Population Center, and Sun Microsystems.

Sampling procedure
---------------------------

MICRODATA SOURCE: Central Statistical Agency

SAMPLE DESIGN: Systematic sample of every 10th household with a random start, drawn by the country. NOTE: The sample includes data from both the short and the long questionnaire. Only one-fifth of household received the long questionnaire, thus only 20% of the population have responses for most variables.

SAMPLE UNIT: household

SAMPLE FRACTION: 10%

SAMPLE SIZE (person records): 7,434,086

Mode of data collection

Face-to-face [f2f]

Research instrument
---------------------------

Two census questionnaires, a short form and a long form, collected information in five sections: 1) Area identification, 2) Type of residence and housing identification, 3) Details of persons in the household, 4) Deaths in the household during the last 12 month, and 5) Information on housing unit. The long questionnaire was administerd to 1 in 5 households in each enumeration area. The short questionnaire with a subset of the long questionnaire items corresponding to basic demographic and social characteristics (population size, sex, age, religion, mother tongue, ethnic group, disability and orphanage) was administered to the remaining (non-sample) households.

摘要
---------------------------
IPUMS-International项目致力于对全球范围内的普查微观数据进行编目、保存、协调和传播。该项目收集了世界上最大的公开普查样本档案。数据在不同国家和地区的时间范围内均进行了统一编码和文档编制，以便利比较研究。IPUMS-International通过网络传播系统向合格研究人员免费提供这些数据。

IPUMS项目是明尼苏达人口中心、国家统计机构和国际数据档案馆之间的合作项目。主要资金由美国国家科学基金会以及国家儿童健康和人类发展研究所的人口统计和行为科学分支提供。此外，明尼苏达大学研究副校长的办公室、明尼苏达人口中心以及Sun Microsystems公司也提供了额外支持。

普查/统计数据 [cen]

抽样程序
---------------------------
微观数据来源：中央统计局

抽样设计：由国家抽取的每隔第十个家庭进行系统抽样，随机起始。注意：样本包括来自简短和长期问卷的数据。只有五分之一的家庭收到长期问卷，因此只有20%的人口对大多数变量有响应。

样本单元：家庭

样本比例：10%

样本量（个人记录）：7,434,086

数据收集方式

研究工具
---------------------------
采用两种普查问卷，分别为简短问卷和长期问卷，收集了五个部分的信息：1）区域识别，2）居住类型和住房识别，3）家庭人员详细信息，4）过去12个月内的家庭死亡情况，以及5）关于住房单位的信息。长期问卷在每一个统计区域的五分之一家庭中实施。简短问卷包含与长期问卷中基本人口和社会特征（人口规模、性别、年龄、宗教、母语、民族、残疾和孤儿）相对应的部分内容，其余非样本家庭则填写简短问卷。
