Measuring occupational sex segregation

What is occupational sex segregation and why is it important?
Women & men work in different types of occupations and at different occupational levels !
3
Why is this of interest?
Last decades an
increasing participation
of women in education + on the labour market
But,
women still predominantly choose typical female fields of study + typical female occupations
And
they are still underrepresented in high status positions
Persistent & universal

Policy level – Equality measure
Degree/level of occupational sex segregation provides information on how unequal the distribution of men and women across occupations and positions is, how men and women are integrated in the workplace, and how separated they are by the work they do. Used as an
‘gender equality measure’… … for designing, evaluating & monitoring employment+social programmes as well as policies!

Measuring occupational sex segregation
Common indices
D = Index of Dissimilarity
(Duncan & Duncan 1955)
D

j J
1
F j F
M j M
Sex segregation = different distribution of women and men across occupations D=0 (complete equality) and 1 (complete dissimilarity) Proportion of women & men who would need to change jobs in order to remove segregation 9
Alternative measures
D st = Standardized Index of Dissimilarity (Gibbs 1965) not affected by occupational size effects should therefore measure ‘pure’ sex typing IP index (Karmel & MacLachlan, 1988) reflects relative size of both sexes + accounts for male & female share of all employed persons should not be sensitive to variations in female labor force share Marginal Matching Index (MM)/Index of Segregation (IS ) (Blackburn 1993) measures changes over time resulting exclusively from changes in sex composition of occupations Association Index (Charles & Grusky, 2004) based on log-linear models WE index (OECD, 1980) SR= Sex-Ratio Index (Hakim, 1979) 10

Role of definitions & classifications
Underestimation of the crucial role of
definitions
and
classifications
in data production. Determine
what is to be covered or not
and with
how much detail
a variable will be described. the
quality of resulting figures.
how well they reflect the
actual situation
of the different participants in the labor market.
12
Determinants of segregation indices
‘
Gender blindness’ of occupational classifications
Aggregated occupational groups masks sex segregation Classifications do not adequately capture important labour market changes
Occupational classifications
Inconsistency
Concept of ‘occupation’
Country-specific occupational classifications might follow different construction principles 13
Occupational classifications
‘Gender blindness’
Classifications cover labour market developments with some delay
Important changes
(e.g. service sector expansion) are not captured adequately (female-dominated sector) Many
new occupations
evolve which are allocated to few & heterogeneous occupational groups.
Level of detail
matters!
14
Occupational detail
Advantage of using disaggregated occupational data broad occupational groups hide occupational sex segregation impacts on the calculation of segregation indices (value of D declines with more aggregation it appears that there is less segregation than there really is) more detailed occupations reveal a more accurate picture of the actual work experience of men & women only then can gender distinction be revealed 15
Which occupations are gendered?
Example: Major group 3 – professionals ‘integrated’
But:
4-digit level!

BUT…
…unfortunately, even very detailed occupational groups may hide occupations’ sex segregation!
WHY?
Tasks & duties
of the same occupation may vary between men and women.
Example:
cleaning occupations (Messing, 1998) & sales occupations (Dixon-Muller, Anker 1990) Female occupations tend to be considered too ‘general’, multitude of tasks linked to general skills (literacy, numeracy & interpersonal contacts & traditional housekeeping activities) 18
Occupational classifications
Problem of inconsistency
Problem:
Changing from 1-digit to more disaggregated 2-/3-digit level some occupations in group 7 obviously require higher degrees of skill & longer training than some of the occupations classified in group 5.
ISCO-08
19
Concept / Measurement of ‘occupation’
Different national & cultural contexts might create
country-specific occupational classifications
following
different construction /measurement principles
are transferred into ISCO08 classification how ‘genderblind’ are these different measures? 20
Conclusion
Occupational classifications should describe men & women’s work characteristics equally well and detailed.
Provision of additional ‘gender relevant’ (job) information (i.e. tasks and duties, skills etc.) providing insights into how sex segregation works within occupations.
Use of aggregated indices as a measure of equality to evaluate progress should be limited!
