  1. Some Results Occupational Socioeconomic Status Groupings and Intercensal Changes in Multiple Job Holding - 1981 to 2001 James Newell Monitoring and Evaluation Research Associates (MERA) Research Forum – Participation in Work in NZ 23 March 2005

  2. What are the changes in MJH Rates 1981 – 2001 and what drove them? • Are the changes in MJH rates for different intercensal periods by occupation explained in terms of socio-economic status, or lifecycle stage? Comparison between NZSEI, Per Hourly Income, Per Capita Household Income and Personal Income scores across occupations in 1991 / 96 Distribution of change in MJH across socioeconomic status groups • Examples of Lifecycle Stage and Birth Cohort Effects in the 1981 to 2001 Trends in MJH Rates Differences by Gender and Ethnic Group

  3. Harmonised Occupational Classifications and NZSEI Groupings • 1991 to 2001 Occupational Series linking NZSCO90, NZSCO95 and NZSCO99 • coherent common denominator classification achieved • 1981 and 1986 on NZSCO68 • No clean common denominator with NZSCO90 – NZSCO99 • Screened out those with poor fit to NZSCO68/NZSCO9099 concordance • Best fit works for the analysis covering 93% of workers • Grouped occupational groups level 3 into NZSEI groups for the analysis

  4. Converting Income Distribution for Occupation into a single Income Rank Score • Income variable score range split into decile groups • estimated hourly income • Personal income • Per capita equivalent household income • Converted into a single income rank score for each occupation • Income Rank Score = Sum of (Decile Index * Percent of Occ in Decile)

  5. Correspondence of Income and Educational Indicators and NZSEI of Occupational Group

  6. NZ Socioeconomic Index of Occupational Status (NZSEI) and Estimated Hourly Income

  7. Intercensal Change in Multiple Job Holding Rate by NZ SEI Group

  8. Intercensal Change in Multiple Job Holding Rate by NZ SEI Group

  9. High SEI Groups Composition

  10. Low SEI Groups Composition

  11. Number of Persons by NZ SEI Group

  12. Number of Multiple Job Holders by NZ SEI Group

  13. Intercensal Change in the Number of Multiple Job Holders by NZ SEI Group

  14. Characterising MJH increases for different Intercensal Periods

  15. Characterising MJH increases for different Intercensal Periods • MJH Rate increases in the 1980’s • An economic adaptation by lower socio-economic status groups • In the 1990’s largest increases in MJH at top and bottom of SEI scale • amongst higher income professionals – sharing specialist skills between different organisations? • at the extreme of low income occupations • maximising income through longer hours • splicing part time jobs into a full time income • Decrease in MJH Rate in mid – SEI Gps 1996-2001

  16. Changes in MJH rates 1981 to 1996 • 1981-1986 • MJH as part of increasing the spread of income by work force with a foothold in agriculture, forestry, fishing and tourism/recreation? • 1986-1991 • MJH as a income diversification strategy for survival in a recessionary period? • 1991-1996 • Rapid Increase in MJH as a way of making best use of and sustaining specialised services / skills in a diversifying and expanding economy • Big increase in MJH amongst lowest SEI groups maximise income and turning part time occupations into full time income

  17. Changes in MJH rates 1996 to 2001 • 1996-2001 • Largest increase amongst low SEI groups (making multiple part time jobs into equivalent of full time job?) • Continued but slower Increase in MJH as a way of making best use of and sustaining specialised services / skills in a diversifying and expanding economy • Decline in MJH as a strategy for maximising income by mid range socioeconomic status groups

  18. Where to : Effects of changes in MJH Rates on Work Life Balance for Different Segments and Periods • Use the framework developed from intercensal occupational and subpopulation age cohort analysis • Explore changes in indicators related work – life balance • hours of work changes for specific groups • Family / lifecycle stage / household context
