IPUMS

Last updated

Integrated Public Use Microdata Series (IPUMS) is the world's largest individual-level population database. IPUMS consists of microdata samples from United States (IPUMS-USA) and international (IPUMS-International) census records, as well as data from U.S. and international surveys. The records are converted into a consistent format and made available to researchers through a web-based data dissemination and analysis system. [1]

Contents

IPUMS is housed at the Institute for Social Research and Data Innovation (ISRDI), an interdisciplinary research center at the University of Minnesota, under the direction of Professor Steven Ruggles. [2]

Description

IPUMS includes all persons enumerated in the United States Censuses from 1850 to 2020 (though, the 1890 census is missing because it was destroyed in a fire) and from the American Community Survey since 2000 and the Current Population Survey since 1962. IPUMS includes household-level data for United States Censuses from 1790 to 1840, due to the first six censuses only including the name of the head of household, with tallied household totals following. [3] IPUMS provides consistent variable names, coding schemes, and documentation across all the samples, facilitating the analysis of long-term change. [4]

IPUMS-International includes countries from Africa, Asia, Europe, and Latin America for 1960 forward. The database currently includes more than a billion individuals enumerated in 365 censuses from 94 countries around the world. [5] IPUMS-International converts census microdata for multiple countries into a consistent format, allowing for comparisons across countries and time periods. Special efforts are made to simplify use of the data while losing no meaningful information. Comprehensive documentation is provided in a coherent form to facilitate comparative analyses of social and economic change. [6]

Additional databases in the IPUMS family include the:

The Journal of American History described the effort as "One of the great archival projects of the past two decades." [12] Liens Socio, the French portal for the social sciences, gave IPUMS the only “best site” designation that has gone to any non-French website, writing “IPUMS est un projet absolument extraordinaire...époustouflante [mind-blowing]!” [13]

The official motto of IPUMS is "use it for good, never for evil." [14] All IPUMS data and documentation are available online free of charge.

A census is the procedure of systematically acquiring, recording and calculating population information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses include censuses of agriculture, traditional culture, business, supplies, and traffic censuses. The United Nations (UN) defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every ten years. UN recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practices.

The American Community Survey (ACS) is a demographics survey program conducted by the U.S. Census Bureau. It regularly gathers information previously contained only in the long form of the decennial census, including ancestry, citizenship, educational attainment, income, language proficiency, migration, disability, employment, and housing characteristics. These data are used by many public-sector, private-sector, and not-for-profit stakeholders to allocate funding, track shifting demographics, plan for emergencies, and learn about local communities. Sent to approximately 295,000 addresses monthly, it is the largest household survey that the Census Bureau administers.

The GermanSocio-Economic Panel is a longitudinal panel dataset of the population in Germany. It is a household based study which started in 1984 and which reinterviews adult household members annually. Additional samples have been taken from time to time. In 2015, there will be about 14,000 households, and more than 30,000 adult persons sampled. Some of the many topics surveyed include household composition, occupation, employment, earnings, health and life satisfaction. The annual surveys are conducted by the German Institute for Economic Research and the Kantar Group. The survey is funded by the German Federal Government and the State of Berlin via the «Bund-Länder-Kommission» for Educational Planning and Research Promotion.

Historical demography is the quantitative study of human population in the past. It is concerned with population size, with the three basic components of population change, and with population characteristics related to those components, such as marriage, socioeconomic status, and the configuration of families.

<span class="mw-page-title-main">Survey (human research)</span> List of questions aimed at obtaining data from a group of people

In research of human subjects, a survey is a list of questions aimed for extracting specific data from a particular group of people. Surveys may be conducted by phone, mail, via the internet, and also at street corners or in malls. Surveys are used to gather or gain knowledge in fields such as social research and demography.

In the study of survey and census data, microdata is information at the level of individual respondents. For instance, a national census might collect age, home address, educational level, employment status, and many other variables, recorded separately for every person who responds; this is microdata.

The American Time Use Survey (ATUS), sponsored by the Bureau of Labor Statistics (BLS) and conducted by the United States Census Bureau (USCB), is a time-use survey which provides measures of the amounts of time people spend on various activities, including working, leisure, childcare, and household activities. The survey has been conducted annually since 2003.

The North Atlantic Population Project (NAPP) is a collaboration of historical demographers in Britain, Canada, Denmark, Germany, Iceland, Norway, and Sweden to produce a massive census microdata collection for the North Atlantic Region in the late-nineteenth century. The database includes complete individual-level census enumerations for each country, and provides information on over 110 million people. This large scale allows detailed analysis of small geographic areas and population subgroups.

The Minnesota Population Center (MPC) is a university-wide interdisciplinary research center at the University of Minnesota. MPC was established in 2000, absorbing two earlier population research organizations. The primary goals of the center are to foster large-scale cross-disciplinary research collaborations and to provide shared infrastructure for demographic research. The center now has 100 faculty affiliates from 10 University of Minnesota Colleges, over 50 graduate student affiliates and 120 administrative and research staff.

Statistics Botswana (StatsBots) is the National statistical bureau of Botswana. The organization was previously under the Ministry of Finance and development planning as a department and was called Central Statistics Office. The organisation was initially set up in 1967 through an Act of Parliament – the Statistics Act and thereafter transformed into a parastatal through the revised Statistics Act of 2009. This act gives the Statistics Botswana the mandate and authority to collect, process, compile, analyse, publish, disseminate and archive official national statistics. It is also responsible for "coordinating, monitoring and supervising the National Statistical System" in Botswana. The office has its main offices in Gaborone and three satellite offices in Maun, Francistown and Ghanzi. The different areas in statistics that should be collected are covered under this Act and are clearly specified. The other statistics that are not specified can be collected as long as they are required by the Government, stakeholders and the users.
