  1. MCRDC Michigan Census Research Data Center The MCRDC is a joint project of the U.S. Bureau of the Census and the University of Michigan to enable qualified researchers with approved projects to access confidential, unpublished U.S. Census Bureau data MCRDC on the web: http://www.isr.umich.edu/src/mcrdc/

  2. Agenda • What is an RDC? • What data are available in the RDC? • What is the process for getting access to RDC data?

  3. Purpose of Census Research Data Centers • Access to data • Secure facility • Presence of Census Bureau employee • Benefits to Census Bureau • Necessary for access to Census • Not required for NCHS, AHRQ data if not linked to Census data

  4. RDCs around the country • Ann Arbor, Michigan • Boston, Mass. • UCLA • Berkeley (new Stanford branch) • Baruch (NYC) • Ithaca (Cornell) • Research Triangle, NC (Duke) • Chicago, Illinois • Minneapolis, Minn. • Washington, DC • Atlanta, Texas, and Mississippi (eventually)

  5. Why use MCRDC data • Not available elsewhere • Establishment level business data • Linked household-firm (LEHD) data • More detail than anywhere else • Detailed geo-spatial variables • Virtually no top or bottom coding • Possible to link to other non-Census data

  6. Disclosure Issues All output goes through disclosure review process Disclosure review process checks to make sure no confidential information is reviewed

  7. Data available in Census Research Data Centers

  8. Decennial Census 1970, 1980, 1990 & 2000 • Comparison to Public Use Micro Sample (PUMS) • Lowest level of geography available in the PUMS is an area that is roughly equivalent to a county but contains 100,000 people (PUMA) • RDC version includes more detailed geographic information • current residence: block level • place of work: census defined place • prior place of residence: place • This allows geographical linking and aggregation to nonstandard units

  9. American Community Survey • Replaces the long form • Household or person-level data • Detailed geography (census block) • Little top or bottom coding • 1996 through 2007 currently available • Can be linked to other data sources, where feasible and permissible

  10. Longitudinal Business Database • Annual data on all non-farm establishments with paid employees, 1976 – 2005 • Manufacturing back to 1967 • 20+ million establishments each year • Excludes airlines, agriculture, RR • LBD includes • Payroll • Employment • Ownership • Detailed geographic information • Industry at 6-digit NAICS

  11. Small Business Data • Integrated Longitudinal Business Data • Universe of all U.S. business establishments without paid employees with linkages that allow a full integration with employer businesses • Every 5 years from 1977 through 1992 • Every year from 1994 through 2005 • 20+ million observations per year • Characteristics of Business Owners • 1982, 1987, 1992, 1994 • 100,000 + owners surveyed • Over-sample of women & minorities • Details on business operations and outcomes • 1997 larger sample but just a little demographic information on business owners • 2002 Survey of Business Owners • More detail on business operations and outcomes

  12. Employer-Employee Linked Datasets • LEHD: Longitudinal Employer – Household Dynamics • Quarterly data on employment and earnings from state unemployment insurance agencies • Contains demographic, employment and earnings data for all employees • All employers linked to employees and to LBD • About ½ the states are currently participating

  13. Virtual RDC • Provides replica computing environment to that in Census RDCs • Zero observation data sets available • Available variables • Data set structure • Ability to write code outside RDC and while awaiting approval of proposal • Data sets available include Decennial, LEHD, LBD, AHS • Synthetic versions of SIPP-SSA and LBD • Available at http://rdc.ciser.cornell.edu/news/

  14. Proposal Process • Preliminary proposal • Create account at Census • http://www.ces.census.gov/ • On line submission • Briefly describe topic and data requested • Full proposal to Census (15 pgs) • Must work with RDC in preparing proposal • Must include benefits to Census as predominant purpose (unless asking for NCHS or AHRQ data) • Reviewed by Census Bureau’s researchers and external researchers

  15. Funding • The MCRDC is supported by • National Science Foundation • Institute for Social Research, including the Survey Research Center, the Population Studies Center, and the Inter-University Consortium for Political and Social Research • University of Michigan and Michigan State University • Most researchers pay $15,000 per year for access to Census RDCs • Access is provided at no charge to UofM and MSU graduate students and faculty
