IPUMS-International disseminates harmonized census microdata for more than 80 countries at no cost, although access is restricted to bona-fide researchers and students who agree to the stringent conditions-of-use license. Currently over 270 samples are available, totaling more than 600 million person records. Each year, 15–20 additional samples are...

The IPUMS-International project, now in its fifteenth year, integrates and disseminates population microdata for twenty-two African countries (82 countries world-wide) and the number continues to increase as more National Statistical Offices cooperate with the initiative. Statistical quality is a serious concern both for the producers of the microd...

The Integrated Public Use Microdata Series (IPUMS) International partnership is a project of the Minnesota Population Center and national statistical agencies, dedicated to collecting and distributing census data from around the world. IPUMS is currently disseminating data on over a half-billion persons enumerated in more than 250 census samples fr...

IPUMS-International disseminates population census microdata at no cost for 69 countries. Currently, a series of 212 samples totaling almost a half billion person records are available to researchers. Registration is required for researchers to gain access to the microdata. Statistics from Google Analytics show that IPUMS-International's lengthy, p...

The Minnesota Population Center (MPC) provides aggregate data and microdata that have been integrated and harmonized to maximize crosstemporal and cross-spatial comparability. All MPC data products are distributed free of charge through an interactive Web interface that enables users to limit the data and metadata being analyzed to samples and vari...

The North Atlantic Population Project (NAPP) is a massive database of historical census microdata from European and North American countries. The backbone of the project is the unique collection of completely digitized censuses providing information on the entire enumerated populations of each country. In addition, for some countries, the NAPP incl...

In the last decade, a revolution has occurred in access to census microdata for social and behavioral research. More than 325 million person records (55 countries, 159 samples) representing two-thirds of the world's population are now readily available to bona fide researchers from the IPUMS-International website: www.ipums.org/international hosted...

Gracias al pionero esfuerzo del doctor Gustavo Cabrera y de otros grandes próceres de la demografía, en América Latina sobrevive un vasto archivo de microdatos censales; sin embargo la mayor parte de ellos se mantiene inaccesible a los investigadores.En la trayectoria académica y científica del profesor Cabrera ha sido constante su preocupación por...

This new project will create two large parallel series of historical U.S. census microdata. The first is a redesigned Integrated Public Use Microdata Series (IPUMS) incorporating Census 2000 and the American Community Survey. The IPUMS is a compatible series of large census microdata samples spanning the period from 1850 to 2000. The second is a re...

This new project will create two large parallel series of historical US census microdata. The first is a redesigned Integrated Public Use Microdata Series (IPUMS) incorporating Census 2000 and the American Community Survey. The IPUMS is a compatible series of large census microdata samples spanning the period from 1850 to 2000. The second is a rest...

Integrated Public Use Microdata Series-International (IPUMS-International) is an effort to inventory, preserve, harmonize, and disseminate census microdata from around the world. IPUMS-International aims to convert census data from five continents into a uniformly coded and fully documented data series. Nearly all countries included in the data ser...

The goal of this article is to present a number of statistical series that can serve as reference data. One is put in a position analogous to that of past census statisticians, having to decide what to present in a limited space and how to make it most useful for subsequent applications. In essence, from our current vantage, modern researchers have...

A new project at the University of Minnesota will provide data extraction and distribution over the Internet of the Integrated Public Use Microdata Series – a database which integrates all existing national samples of the US census from 1850 to 1990 into a consistent format.

The historical record rarely presents researchers with precisely the evidence they desire. This is particularly true for social historians and like-minded scholars, whose subjects left precious few signs of their passing. Consequently, certain data have borne a disproportionate evidentiary load in social-historical research. The occupation a person...

In this article I will examine the possibilities for a Marxist analysis of class through the use of the information available in the various U.S. census public use samples....The public use samples are machine-readable individual- and household-level microdata samples entered from the original census manuscripts....Public use samples of varying den...

Integrated census microdata constitute a new resource for social science research and policy making. The IPUMS-International project (www.ipums.org/international) is a global initiative in cooperation with national statistical authorities world-wide to anonymize, integrate and disseminate samples of census microdata. Extracts adapted to the specifi...

Thanks to cooperative undertakings with national statistical agencies world-wide and to sustained funding by the National Science Foundation and the National Institutes of Health of the United States, over the next five years the University of Minnesota Population Center is extending the IPUMS-International project to 44 countries, including at lea...

In African countries, census data provide critical information on current and historical trends in households and family relationships. We use data from IPUMS-International and the African Integrated Census Microdata Series (AICMD), a freely available database of 52 million person records from 13 African countries, from the 1980s through the 2000s....

Introduction. Census microdata samples are an invaluable resource for social science and policy research. Other sources—such as demographic and labor force surveys—often offer greater subject coverage and detail than do census data, but no alternate source offers comparable sample density, chronological depth, and geographic coverage. For much of t...
