Course Offered: "American Community Survey: Research Applications and Challenges"
Instructor(s): Barry Edmonston, Portland State University and Census Bureau Staff
Dates: August 8-10
Location: Ann Arbor, MI
Fee: ICPSR Member: None; Nonmember: $1600
This course is intended to present participants with an understanding of the purpose, structure, and research applications of the American Community Survey (ACS). Similar to data products from the decennial census - including summary tabulations and Public Use Microdata Sample (PUMS) files - the ACS is intended to be its replacement. ACS will provide summary tabulations for geographic areas and microdata files each year containing demographic, social, economic, and housing data on the population of the United States.
Building on data collection work that began in 1996, the U.S. Census Bureau entered full production mode for ACS at the beginning of 2005 with the mailing of questionnaires to a rolling, random annual sample of approximately 3 million households. The Census Bureau expects to release data for areas with populations of 65,000 or more in 2006 and for smaller geographic areas in subsequent years with the aggregation of data over several years.
Workshop activities will be oriented toward individuals who expect to use the ACS in their research. The first part of the workshop, presented by officials from the Census Bureau, will focus on ACS structure, content, and schedule of data releases. The second part of the workshop will concentrate on current and prospective research uses of these data and will include such topics as how ACS data are organized, how data are accessed, and special features of these new data. Examples of analysis of ACS data will feature such topics as schooling and immigration.
Application materials are due by April 29, 2005. For details on how to apply, please visit the Summer Program Web site.

Census 2000: Data Structures and GIS Applications
Instructor(s): Peter Granda, ICPSR, University of Michigan
Dates: June 21-25
Location: Ann Arbor, MI
Fee: ICPSR Member: None; Nonmember: $1,100
This course is intended to present participants with the major data products of the 2000 Census and to provide a practicum in their use with a special emphasis on GIS applications. Activities will be oriented toward individuals who expect to use the 2000 Census data in their own research or who plan to assist others in utilizing these data. The first part of the workshop will emphasize discussion of 2000 Census products: Census concepts, terminology, geography as well as the structure and content of the various 2000 Census data files. This intensive workshop will also offer opportunities for hands-on computing experiences with Census data files. The discussions and computing activities will concentrate on both aggregate data (Summary Files from both the short [100 percent] and long [sample] census forms) and microdata (the Public Use Microdata Sample files [PUMS]) with a particular emphasis on Census geographic concepts. The second part of the workshop will focus on using GIS software with Census data and on practical research applications. Personnel from the Bureau will assist in presentations of material in the workshop. Enrollment in the course is limited. Applications must include a vita and cover letter describing the applicant's background and interest in Census data. Individuals who are applying for this course should check the Competitive 3- to 5-Day box on the ICPSR application form. Application materials are due by Monday, April 26, 2004.

New Deadline for Application to MCRDC Announced
To benefit its members, ICPSR is purchasing a "seat" in the Michigan Census Research Data Center (MCRDC), and researchers from ICPSR member institutions may apply to use the seat without paying MCRDC laboratory fees. The MCRDC enables qualified researchers with approved projects to conduct research using unpublished data from the Census Bureau's economic and demographic programs. All MCRDC research is conducted within its secure laboratory facility located in the Institute for Social Research at the University of Michigan.
Researchers are invited to submit proposals to use the MCRDC. All research in MCRDC must have a Census Bureau purpose. Please refer to the MCRDC and the Census Bureau Center for Economic Studies (CES) Web pages (see below) for information about the proposal process and about available datasets. Researchers with projects in the MCRDC must have special sworn status with the Census Bureau. The MCRDC assists researchers in obtaining this status.
The next deadline for proposal submission is January 15, 2004. Subsequent deadlines are in mid-May and mid-September.
To apply to use the ICPSR-supported seat, researchers should submit a copy of their MCRDC research proposal, together with a brief letter requesting use of the ICPSR seat, to Erik Austin, ICPSR Assistant Director and Director of Archival Development, at least one week before submission of a proposal to the MCRDC. Note that ICPSR's role in the application process is only to verify ICPSR membership and does not involve proposal review. More detailed information about the MCRDC as well as tips on writing successful proposals can be found on the MCRDC Web site.
To contact staff at the center, send email to mcrdc@umich.edu. For more information about ICPSR support for research at the MDRDC, contact Erik Austin at erik@icpsr.umich.edu.
