  3. I&O Data Uses: Government • to formulate policy and programs for employment, career development and training • to provide information on the occupational skills of the labor force in a given area to analyze career trends • to help create estimates used in the allocation formulas or for eligibility criteria in many federal programs

  4. I&O Data Uses:Businesses • to measure compliance with antidiscrimination policies • to decide where to locate new plants, stores, or offices • to develop business plans • to plan, budget, and pay benefits

  5. I&O Data Uses:Researchers • to analyze social and economic issues, such as • earnings inequality • labor force transitions • employment outcomes • returns to education

  6. Examples of ACS I&O Data Uses • National Science Foundation’s Survey of College Graduates • Uses 2009 ACS as sample based on field of degree and occupation • EEO Special Tabulation • Equal Employment Opportunity Commission • Department of Justice – Civil Rights Division • Department of Labor – Office of Federal Contract Compliance • Office of Personnel Management

  7. EEO Special Tabulation • External benchmark for conducting comparisons between the racial, ethnic, and sex composition of each employer's workforce to its available labor market • Used by organizations to develop and update their affirmative action plans

  8. Surveys Using Census I & O Coding • American Community Survey • Current Population Survey • Survey of Income and Program Participation • American Time Use Survey • National Crime Victimization Survey • National Health Interview Survey • New York City Housing Vacancy Survey • National Survey of College Graduates

  9. ACS I & O Data Process Data capture Questionnaire completion (collection) Clerical coding Edits • Paper • CATI • CAPI • Coding file for I&O • Qualified coders • Referralists • QA • Keyed from image (KFI) • Data capture file

  10. Capture Collection Coding Edits 3 Modes of Data Collection

  11. ACS Paper Questionnaire • 3 million addresses annually • 5 demographic questions • 21 housing questions • 48 population questions • I&O Questions # 41-46

  12. Everyone 15 and older who had a job during the past 5 years • With a job last week • Only 1 job • Job with most hours • If not working last week • Most recent job in past 5 years

  13. ACS Questionnaire Class of Worker Item • Class of worker categorizes people according to the type of ownership of the employing organization

  14. ACS Questionnaire Industry Items • Industry data describe the kind of business conducted by a person’s employing organization • 3 industry questions

  15. ACS Questionnaire Industry Type Check box • Check box on industry type

  16. ACS Questionnaire Occupation Items • Occupation describes the kind of work a person does on the job • 2 occupation questions

  17. Collection Capture Coding Edits Data Capture at Jeffersonville, IN

  18. Data Capture from Questionnaires

  19. Creation of Data Capture File • About 45 keyers daily at National Processing Center • Truncate write-ins to 60 characters for I&O items • Illegal value responses identified

  20. Data Capture File • Age • Sex • Date of birth • Educational attainment • Class of worker checkbox • Armed forces checkbox • Employer name write-in • Kind of business write-in • Industry type checkbox • Kind of work write-in • Duties write-in • Geographical information

  21. Example of Write-ins

  22. Collection Coding Edits Capture I & O Coding • All ACS I&O coding is computer assisted clerical coding • Over 200,000 ACS cases per month • Batches of 100 cases at a time

  23. Coding Process

  24. I&O Coding System Industry, occupation, or military Index Industry code Occupation code

  25. Census I&O Codes • Unique set of codes for household surveys • Collectability – observable detail on write-in • Degree of aggregation varies by sector or major group • Updated with NAICS and SOC changes

  26. Industry Codes NAICS Manual-Industry • Census industry codes based on NAICS • Covers all 20 sectors • Classified based on NAICS two-digit through six-digit codes • 269 Census industry codes

  27. Industry Code Crosswalk (excerpt)

  28. Occupation Codes SOC Manual-Occupation • Census occupation codes based on SOC • Covers all 23 major occupational groups • Classification detail based on SOC two-digit through six-digit codes • 539 Census occupation codes

  29. Occupation Code Crosswalk (excerpt)

  30. Coding Indexes

  31. Collection Edits Coding Capture Edits: Universe Check For each person record: Age > 15 Worked in past 5 years

  32. Incomplete Data: Logical Edits • Incomplete entries can be corrected using the Alphabetical Index of Industries and Occupations

  33. Incomplete Data: Assignment from Donors Donor respondent -- a “similar” person based on characteristics such as age, sex, educational attainment, income, employment status, and weeks worked • Used to fill missing item when • missing code for industry, occupation, class of worker item • All labor force and income data are blank, all of these economic questions are assigned from a “similar” person who had provided all these data

  34. Consistency Check • Evaluates consistency among all of the labor force, education, and income data

  35. Example of an Edit: Occupation = Lawyers • Where AGE > 15 and EMPLOYED and OCCUPATION CODE is “Lawyers” • EDUCATIONAL ATTAINMENT < Master’s degree and INCOME per Week is less than $930 • Make OCCUPATIONAL CODE = “Paralegals and legal assistants”
