Population and Housing Census 1989 - IPUMS Subset - Viet Nam

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.

Geographic coverage

Kind of data
---------------------------

Census/enumeration data [cen]

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

MICRODATA SOURCE: Constructed by census agency. Microdata files from floppy discs dated April 19, 1995

SAMPLE DESIGN: Stratified systematic sample of enumeration areas. Strata correspond to 80 geographic areas, according to urban/rural and provinces/cities. All dwellings/households within an enumeration area are included in the sample.

SAMPLE FRACTION: 5%

SAMPLE SIZE (person records): 2,626,985

Mode of data collection
---------------------------

Face-to-face [f2f]

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

Two forms: long (5% sample survey) and short (remaining 95% of the population). The long form contained both the core and sample questions. Dwelling questions covered 19 provinces/cities, not necessarily corresponding to the sample survey.

Response rate
---------------------------

UNDERCOUNT: No official estimate

摘要
---------------------------
IPUMS-International项目致力于全球范围内人口普查微观数据的盘点、保存、协调与传播。该项目汇聚了全球规模最大的公开人口普查样本档案。数据在各国及不同时间点的编码和记录保持一致性，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项目是由明尼苏达人口中心、国家统计机构和国际数据档案馆共同合作的项目。主要资金来源于美国国家科学基金会和儿童健康与人类发展国家研究院的人口与行为科学分支。此外，明尼苏达大学研究副校长办公室、明尼苏达人口中心和Sun Microsystems也提供了额外支持。
