Family-member characteristics are often related to individual outcomes. The IPUMS data extract system makes it easy for you to include in your datasets variables that describe other household members, such as age of mother, occupation of father, or educational attainment of spouse.
In April, MPC Director of Data Integration Matt Sobek was invited to speak at an event for the United Nations’ 49th Session of the Commission on Population and Development. The special session, “The Data Revolution in Action: National and International Experiences with Microdata Dissemination and Public Use,” was created to show attendees examples of national and international organizations distributing data for public use.
A year ago, the MPC’s Integrated Health Interview Series (IHIS) project launched their IHIS Data Briefs. IHIS offers an integrated version of the National Health Interview Surveys (NHIS). “The data briefs were a natural fit for the NHIS data,” says Julia Rivera Drew, co-principal investigator of IHIS and co-author of the Data Briefs. “We realized that there were great resources that were going underutilized in NHIS and this provided a way to let users know the contents of the database. The briefs allow us to introduce topics that our users may have been interested in, but didn’t know we covered.” The briefs have also helped Drew and her colleagues reach out to new kinds of users.
NHGIS recently launched a pair of web maps highlighting the available GIS files and striking changes in boundaries over time for two popular geographic levels. The ‘Census Tract’ map displays data for years 1910 to 2014, and the ‘Place’ map depicts data for 1980 to 2014. With each year listed as a separate layer, users can easily toggle specific years on and off to visualize the data.
Associate Professor of History and MPC Faculty Member J. David Hacker made headlines in 2011 when he published a groundbreaking study of the total number of U.S. Civil War dead. Hacker argued that the widely-accepted figure of 620,000 was far too low. Using IPUMS, Hacker showed that the number of dead was at least 750,000—if not more. His article, “A Census-Based Count of the Civil War,” published in Civil War History, was introduced by the editors in the issue as “among the most consequential pieces ever to appear in this journal’s pages.”
Few demographic historians expect attention from mainstream press when they publish their research, but Hacker’s study attracted national interest, including interviews with the New York Times and National Public Radio.
How and to what extent do our leaders and decision-makers need to address migration as a climate change issue? This issue was at the forefront of our minds recently when we had the unique opportunity to attend the 21st annual climate talks, known as the Conference of the Partners (COP21), in Paris, France in November and December of last year.
We participated in COP21 as part of a wider delegation from Minnesota that included past and current Minnesota state representatives, St. Paul Mayor Chris Coleman, and several other representatives from government and non-governmental organizations. Like previous meetings, the goal of COP21 was to convene a meeting of world leaders and to negotiate a global climate treaty, laying the groundwork for preventing global average temperatures from rising no further than a maximum of two degrees Celsius above preindustrial levels.
By 2020, MPC will make freely available to researchers worldwide 100% count U.S. Census microdata through 1940. This dataset will include over 650 million individual-level (1850-1940) and 7.5 million household-level records (1790-1840). The microdata represents the fruition of longstanding collaborations between MPC and the nation’s two largest genealogical organizations—Ancestry.com and FamilySearch—to leverage genealogical data for scientific purposes.
“The importance of this massive donation of census data would be difficult to overstate,” says MPC Director Steve Ruggles. “This is one of the largest-scale data-entry efforts ever undertaken.”
