Ipums codebook6/29/2023 ![]() This paper focuses on the IPUMS-International “collaboratory” ( Cogburn, 2003:89), specifically the functioning of trans-border dissemination of microdata and the exchange of research results.įor orientation, readers are invited to examine the IPUMS websites. The first release will include samples for …#. In 2014, an IPUMS integrated version of Measure Demographic and Health Surveys will be launched using the IPUMS extract engine for dissemination. TerraPop seeks to harness census microdata to global-scale data on land use, land cover, climate change and more. ![]() ![]() In 2012, the MPC launched the Terra Populus initiative to construct a global population and environment network. A NAPP ambition is to construct life histories for immigrants and non-immigrants alike through the full corpus of censuses over time and across borders for the entire North Atlantic region. Person records total in the hundreds of millions. At present NAPP disseminates integrated historical microdata for six countries-Canada, Great Britain, Iceland, Norway, Sweden, and the United States (see Full-count microdata, including names of individuals, are available for eleven censuses, covering entire national populations. In 2003, the North Atlantic Population Project, also hosted by the MPC, began with a focus on microdata from nineteenth century population censuses. Worldwide, IPUMS-International seeks to engage with other national, regional and international academic, government and non-governmental partners. For Europe, the IECM project performs a similar function as well as facilitating linkages with the European Union-funded Data without Boundaries project ( The DwB initiative seeks to promote access and research for all kinds of European microdata. The AICMD is crucial for networking with the large number of African countries, statistical organizations, universities, and researchers over the sprawling, diverse continent. The Europe portal, is operated by the Center for Demographic Studies in Barcelona. Two continental portals complement the international website with optimized metadata, networking features, and other enhancements: More than one-half billion integrated microdata records, spanning three-quarters of the world’s population, are currently in dissemination. Usage grew even faster, doubling every two or three years. The ensuing ten years saw a ten-fold increase in the number of countries and samples available to researchers. In 2002, the IPUMS-International site ( ) was born, offering pooled extracts of confidentialized, integrated samples for six countries: Colombia, France, Kenya, Mexico, the United States and Vietnam. The updates include triennial and quinquennial versions of the ACS as well as annual. Annually, the USA site is updated with American Community Survey (ACS) samples within a week or two after release by the Census Bureau. Each extract is pooled into a single data file, regardless of the number of samples requested. Today, “IPUMS-USA” disseminates custom-tailored extracts of samples for any of the USA censuses from 1850 to 2010. Two years later, the first internet website went on-line for Integrated Public Use Microdata Series (IPUMS), and dissemination by tape was quickly forgotten. For academics old enough to remember 7-track computer tape, this was the medium of dissemination with sixty million integrated person records packed on a single reel. In 1993, the microdata revolution in the United States began with the first release of samples for nine censuses for one country, spanning the period 1880–1990. Likewise, Dot-Coms beckon as a new jobs frontier opens for savvy Big Data users ( Lohr, 2012:B2). According to a former president of the Population Association of America, students of the Big Census Data Revolution, specifically those with analytical experience using integrated census microdata, enjoy advantages for internships and employment at the World Bank and similar agencies ( Meier, Lam and McCaa 2011). The revolution has sparked much new research. Steven Ruggles, the Center’s founding director. The IPUMS project is the brainchild of Dr. The website is hosted by the Minnesota Population Center. Now, from many decades of census microdata samples for much of the world are readily accessible anywhere, free of cost to researchers and students-regardless of country of birth, residence or citizenship. Then, census microdata samples were available for only a handful of countries and trans-border access was difficult for all but a few. ![]() The Big Census Data Revolution, foretold a decade ago in Scandinavian Population Studies ( McCaa and Ruggles 2002), has arrived, but it is not yet complete. ![]()
