What Is Occupational Segregation?

Occupational segregation refers to the unequal distribution of different groups of people across occupations or types of jobs. In labor economics, the term is most commonly used to describe differences in the kinds of jobs held by men and women, although occupational segregation can also occur by race, ethnicity, age, disability, immigration status, or other characteristics. When certain groups are concentrated in particular occupations while being under-represented in others, occupational segregation exists.

Occupational segregation is an important issue because the type of occupation a person enters can strongly influence their wages, career opportunities, job security, working conditions, and chances of reaching management positions. It is therefore closely connected to broader questions of labor-market inequality.

Types of Occupational Segregation

Occupational segregation is generally divided into two main types: horizontal segregation and vertical segregation.

Horizontal occupational segregation occurs when different groups are concentrated in different types of occupations. For example, women may be more strongly represented in occupations such as nursing, teaching, childcare, administration, and social services, while men may be more concentrated in construction, engineering, transportation, and certain technical occupations. This means that men and women may work in the same labor market but tend to perform different kinds of jobs.

Vertical occupational segregation occurs when different groups are distributed unequally across levels of seniority, authority, or status within occupations or organizations. For example, women may represent a large share of employees in a profession but a much smaller share of senior managers or executives. This phenomenon is often described as the “glass ceiling,” referring to invisible barriers that make it more difficult for members of some groups to reach the highest positions.

These two forms can occur simultaneously. A group may be concentrated in relatively low-paying occupations and, even within those occupations, may have fewer opportunities to advance to senior positions.

Why Does Occupational Segregation Occur?

There is no single explanation for occupational segregation. It usually results from a combination of economic, social, cultural, institutional, and historical factors.

One important factor is education and skills. People with different educational backgrounds may enter different occupations. Although educational differences between men and women have changed significantly in many countries, differences in fields of study can still influence occupational choices. For example, one group may be more likely to study engineering or computer science, while another may be more likely to study education, healthcare, or social sciences.

Another factor is social norms and stereotypes. From an early age, individuals may receive messages about which occupations are considered appropriate for men or women. Children may be encouraged toward different subjects, activities, and career goals based on gender expectations. These influences can affect educational decisions and occupational choices later in life.

Family responsibilities also play an important role. In many societies, women continue to perform a larger share of unpaid childcare and household work. As a result, some women may prefer or be pushed toward occupations that offer flexible schedules, part-time employment, predictable working hours, or easier career interruptions. These occupations may provide valuable flexibility but can sometimes offer lower wages or fewer opportunities for promotion.

Labor-market institutions can also contribute to segregation. Recruitment practices, workplace cultures, professional networks, and promotion systems may favor particular groups, intentionally or unintentionally. Employers may make assumptions about workers' abilities, availability, or commitment based on their gender or other characteristics. Such assumptions can influence hiring and career advancement.

Finally, historical discrimination can have long-lasting effects. If certain occupations were traditionally closed to particular groups, those groups may have developed less access to the necessary training, professional networks, or role models. Even after formal discrimination disappears, these historical patterns can persist.

Occupational Segregation and the Gender Pay Gap

Occupational segregation is closely related to the gender pay gap. If men and women are concentrated in different occupations and some traditionally male-dominated occupations pay more than traditionally female-dominated occupations, differences in occupational distribution can contribute to average wage differences.

For example, suppose one group is heavily concentrated in highly paid technical and managerial positions while another is concentrated in lower-paid service and care occupations. Even if workers receive similar pay for the same job, the overall average earnings of the two groups may still differ because they are performing different jobs.

However, occupational segregation is not the only cause of the gender pay gap. Differences can also arise from working hours, work experience, career interruptions, education, industry, discrimination, bargaining power, and access to promotions. Occupational segregation is therefore one part of a much larger labor-market process.

Consequences of Occupational Segregation

Occupational segregation can have significant consequences for individuals and society.

For workers, being concentrated in a limited range of occupations may restrict career choices and earning potential. If the occupations associated with a particular group tend to be lower paid, workers in that group may face lower lifetime earnings and reduced economic security.

Segregation can also limit access to leadership and decision-making positions. When certain groups are under-represented in senior roles, organizations may lose access to a wider range of perspectives and talents.

At the broader economic level, occupational segregation can contribute to an inefficient allocation of human resources. If people choose occupations primarily because of social expectations rather than their interests and abilities, the economy may not make full use of its available skills.

There can also be social consequences. Occupational segregation may reinforce stereotypes. When children repeatedly observe particular jobs being associated with one gender, they may come to believe that these patterns are natural or inevitable. This can reproduce occupational segregation across generations.

How Can Occupational Segregation Be Reduced?

Reducing occupational segregation requires addressing its various causes.

Education and career guidance can help challenge traditional assumptions about appropriate careers. Students should have opportunities to explore a wide range of subjects and occupations regardless of gender or background.

Workplace policies can also make a difference. Transparent recruitment and promotion procedures, equal-opportunity policies, flexible working arrangements, and family-friendly benefits can reduce barriers to participation and advancement.

Increasing access to affordable childcare and encouraging a more equal distribution of unpaid household responsibilities can also help. When workers do not have to choose between family responsibilities and career development, they may have greater freedom to pursue a wider range of occupations.

Organizations can further address segregation by examining their own hiring, promotion, pay, and workplace cultures. Mentoring and professional-development programs can help under-represented groups enter occupations where they have historically had limited representation.

Finally, changing social attitudes and stereotypes is essential. Role models can demonstrate that people of any gender or background can succeed in any occupation. Over time, greater diversity within occupations can itself help weaken traditional stereotypes.

Conclusion

Occupational segregation is the unequal distribution of different groups across occupations and levels of employment. It can take the form of horizontal segregation, in which groups work in different types of occupations, or vertical segregation, in which they occupy different levels of authority and seniority.

The causes are complex and include education, social expectations, family responsibilities, workplace practices, discrimination, and historical patterns. Occupational segregation can affect wages, career opportunities, economic security, and the efficient use of human talent.

Reducing occupational segregation does not necessarily mean forcing people into particular careers. Instead, the goal is to ensure that individuals have genuine freedom to choose occupations based on their abilities, interests, and goals rather than stereotypes or structural barriers. A labor market with greater occupational choice and equal opportunity can benefit not only individual workers but also organizations and the economy as a whole.
