2012 Economic Census Changes

• Proposed expansion of geography – publishing as many Census Places as feasible

• North American Product Classification System – changes to manufacturing, retail, and wholesale product detail.

• NAICS 2012 – significant reduction in the number of manufacturing industries (~260 down from ~470)

• Manufacturing “type of operations” may be coming– Integrated Manufacturer– Contract Manufacturer– Factoryless Goods Producers

Complications – e.g. productivity

• Outside of manufacturing we collect input data in a number of programs– Capital

• Annual Capital Expenditures Survey (ACES)• Firm Level

– Employment & Payroll• Business Register, Census, Annuals

– Other inputs (e.g. inventories, benefits)• Annuals• BSR Units

• Relatively few projects request these data, but replacement of the Assets and Expenditures Survey (1992) and Business Expenses Survey (BES) with the Annuals means demand should be increasing.

What is LEHD?

• At its core, LEHD is a National Longitudinal Job Frame

– Based on UI-Wage and other administrative data sources

• Primary Products– Public use products: QWI, OnTheMap– Rich micro data for research in the RDCs

Where does LEHD fit within the Census Bureau’s data infrastructure?

• The Census Bureau maintains national frames of household and business establishments

• Household Frame: Master Address File• Decennial Census, ACS, CPS, SIPP, etc.

• Establishment Frame: Business Register• Economics Census, Monthly and Annual

Surveys, Longitudinal Business Database, County Business Patterns, etc

LEHD is a national jobs frame

• Jobs are the unit of analysis in LEHD data– Jobs are an employer – employee pair for a given time

period• Integrate with

– Person and Household Data via “employee” information– Establishment and Firm data via “employer” information

• Integration permits:– Improved Public Use Products– Richer Microdata for Research (via the Research Data

• Business formation is critical for job and productivity growth• New firms are often small, sole proprietors and an important

fraction start as micro-enterprises (non-employer firms) • By integrating LEHD microdata with business microdata data

researchers can track business startups.– Where did the entrepreneur come from?

• What type of firm was entrepreneur working at?• Are some business types and locations especially effective incubators

of new firms?– What kinds of jobs do start-ups create?

• What kind of job paths are there at successful startups?• Do workers at startups come from the community or are the workers

migrants?

Questions for Research: ExampleDisplaced worker outcomes

• What happens to the workers at establishments that have mass layoff events?– LEHD data allow researchers to follow these workers to their

subsequent jobs – Can examine their wage outcomes and the characteristics of the

businesses that reemploy them.

• Tracking employment outcomes for workers who are displaced• How long does it take to become re-employed?• What types of jobs are they hired into (location,

industry)?• What are the earnings outcomes?

Summary: Research using LEHD data in RDCs• LEHD microdata offer many unique advantages for

economic research:• Longitudinal linked employer-employee data• Follow employment histories of workers • Can identify nascent firms and follow them over time• Can identify co-workers

• Ability to link at the micro (individual, household, establishment, firm) level records from different census, survey and administrative programs, as well as researcher provided data.– Dramatically increases the analytical power of the

data.

Historical Microdata Recovery from Unisys Mainframe

Challenges– Arcane, proprietary file format (CENIO)– Data completely unstructured

• And record layout may no longer exist.– Employed one or more (now) esoteric character sets (not ASCII)

• E.g., FIELDATA, Excess-3, EBCDIC, Binary integer numericRecovered before decommissioning in Spring 2010:

– Over 2,500 tapes containing more than 7,000 files– Business microdata

• Covering nearly all sectors of the economy, including manufacturing, mining, retail, wholesale, services, construction, transportation, and agriculture.

• From as early as 1953 (and perhaps 1947)

Making the Data “Usable”For technical reasons, the data were downloaded from the Unisys in

two forms:– Assuming the data was all Excess-3– Assuming the data was all FIELDATA

If the data is in another character set (e.g., Binary integer numeric) the “gibberish” in the above FIELDATA file must be converted to ASCII using the implied mapping.

Challenges in creating ASCII and SAS datasets:– Data in a record might employ multiple character sets (e.g.,

both Excess-3 & Binary, depending on variable).– Record layout may no longer exist (explaining variables, their

lengths, and character set employed), or it may be wrong.• An electronic file containing the first 100 records using 5 different

assumptions of character set can help reveal variable length & character set.

• Existing microdata (and published data) can potentially help in determining what variables are.

Getting Access to these DataIf research does NOT hinge critically on recovered data

– Submit CES proposal as usual, requesting recovered data• Development of these data can be cited as a benefit• Within 6 months, the researcher provides internal technical note

concerning the data quality, cleaned-up datasets, programs, and documentation

If research DOES hinge critically on recovered data– Feasibility access, provide a brief description of intended research

• Researcher will obtain SSS clearance• Access only to historical data of interest and (if requested) analogous

data for later years for quality assurance purposes

• RDC lab fees are waived• The project has no public output• Within 6 months, the researcher provides internal technical note

concerning the data quality, cleaned-up datasets, programs, and documentation

– Research access, submit CES proposal as usual• Feasibility work can be cited as a benefit

Conclusion

Much more work needs to be done– Constructing linkages– Differentiating between multiple versions of same– “Proving in” the data (e.g., tab to publish totals)

Why is this worthwhile?– Data over a few more business cycles– New baselines, for example:

• The “heyday” of U.S. manufacturing • Before 1970s energy crisis• Before environmental regulation

Start to make plans to use these data!

Why Restrict Microdata Access?

Titles 13 (Census) /26 (IRS) U.S.C. and CIPSEA protect confidentiality– respondent cannot be identified– only Census employees and temporary staff

can access microdata– use limited to statistical purpose– access must potentially provide legitimate

benefits to Census Bureau programs

Conclusions• Start the process early• Use standard data sets if time-constrained• Write proposals geared towards multiple papers• Use proposal development as research time

– Understand the data & data limitations– Read on-line documentation

• CES Working Papers• Sampling Methodology/Survey Forms• History of the Economic Census

• Time and data requests are crucial components – adding data and/or time is difficult for Census projects once underway

• Remember that the Predominant Purpose is to benefit Census
