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unpublished U.S. Census Bureau data

RDC data?
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


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

Disclosure Issues

All output goes through disclosure
review process

Disclosure review process checks to
make sure no confidential information
is reviewed
Data available in Census
Research Data Centers
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
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
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

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




Characteristics of Business Owners


1982, 1987, 1992, 1994
100,000 + owners surveyed


Over-sample of women & minorities
Details on business operations and outcomes


Every 5 years from 1977 through 1992
Every year from 1994 through 2005
20+ million observations per year
1997 larger sample but just a little demographic information on business owners
2002 Survey of Business Owners

More detail on business operations and outcomes
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

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/
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
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

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
