1 Definition and conceptual framework

Underemployment is a labor economics term for work arrangements that do not fully use a person’s labor potential. The concept may refer to insufficient working hours, but it can also describe a job that does not match a worker’s skills, training, or earning capacity. Economists use the term to identify forms of labor market slack that are not captured by unemployment alone.

1.1 Core meaning of underemployment

In its broadest sense, underemployment exists when a worker is employed below the level that would be considered optimal for that person’s abilities or needs. This may mean fewer hours than desired, lower pay than expected from the worker’s qualifications, or duties that fall well short of the worker’s productive capacity. The concept is therefore relative: it depends on the comparison between actual employment and the employment a worker could reasonably obtain or wants to have.

1.2 Distinction from unemployment

Unemployment refers to people who do not have a job but are available for work and actively seeking employment. Underemployment, by contrast, concerns people who do have jobs but are not fully utilized. A worker may be counted as employed in official statistics while still experiencing underemployment because the job is part-time, temporary, or below their skill level. For this reason, underemployment is often treated as a complementary indicator to unemployment.

1.3 Distinction from overqualification

Overqualification is a specific form of skill-related underemployment in which a worker’s education, training, or experience exceeds what the job requires. The terms are closely related, but not identical. Overqualification emphasizes the mismatch between credentials and job demands, while underemployment is broader and may include insufficient hours, low income, or limited responsibility even when the formal qualification match is acceptable.

1.4 Distinction from labor force underutilization

Labor force underutilization is an umbrella concept that includes unemployment, underemployment, and related forms of unmet labor supply. It captures the extent to which available workers are not being used in ways that reflect their capacity or preferences. Underemployment is one component of this wider measurement framework, especially in analyses that aim to assess hidden slack in the labor market.

2 Types of underemployment

Underemployment appears in several forms, depending on whether the main problem is time, skill, or income. These categories often overlap. A worker may, for example, be both working fewer hours than desired and earning too little for their level of training.

Time-related underemployment occurs when a person works fewer hours than desired and is willing to work additional hours. It is especially common in part-time or variable-schedule jobs. In labor statistics, this type is often treated as the most direct measurable form of underemployment.

2.1.1 Part-time work for economic reasons

Part-time work for economic reasons describes workers who would prefer full-time employment but cannot obtain it. Their reduced hours are not chosen for personal convenience; instead, they reflect constraints such as limited employer demand or schedule cuts. This category is often used in official reporting because it signals that labor demand is weaker than the worker’s willingness to supply labor.

2.1.2 Involuntary reduction in working hours

Involuntary reduction in working hours refers to a decrease in scheduled or available hours that the worker did not choose. It may happen because of reduced business activity, temporary layoffs of hours, or changes in seasonal demand. Even when a worker remains attached to an employer, the decline in hours can significantly reduce earnings and labor utilization.

Skill-related underemployment occurs when a worker’s capabilities exceed what the job uses. This form is particularly important in discussions of education, occupational mobility, and the returns to human capital. It can persist even in periods when unemployment is low.

2.2.1 Overeducated workers in low-skill jobs

This situation arises when individuals with college degrees, professional training, or specialized experience work in jobs that require substantially less qualification. The mismatch may be temporary, such as during labor market entry, or longer lasting if career paths are constrained. It can reduce the expected payoff from education and weaken the link between schooling and occupational advancement.

2.2.2 Occupational mismatch

Occupational mismatch occurs when a worker is employed in a field that does not align closely with their training or prior experience. The mismatch may involve a different industry, a different occupation, or a lower level of responsibility. Such misalignment can limit productivity because the worker’s specialized knowledge is not being used effectively.

Income-related underemployment focuses on earnings that are inadequate relative to a worker’s skills, effort, or need for stable income. This category may be caused by low wages, too few hours, or a combination of both. It is especially relevant in analyses of working poverty.

2.3.1 Low earnings relative to skill level

A worker may earn less than would be expected given their education or experience. This can happen when the job market offers limited bargaining power, when the occupation is low paid, or when the worker accepts a lower-paying position after displacement. The issue is not simply the wage level in isolation, but the gap between earnings and productive potential.

2.3.2 Inadequate hours and pay

Some workers receive both low hourly wages and too few hours to produce sufficient income. Even if the wage rate is not unusually low, the combination of short schedules and limited opportunity for overtime can result in financial strain. This pattern is common in service-sector jobs with variable scheduling.

3 Causes of underemployment

Underemployment has multiple causes, and they often interact. Economic cycles, structural change, and institutional factors can each contribute to labor being used inefficiently. A single cause is rarely sufficient to explain all cases.

3.1 Business cycle conditions

During recessions or slow recoveries, firms may reduce hiring, cut hours, or reassign workers to lower-productivity tasks. Workers who cannot find their preferred full-time positions may accept part-time or lower-skill employment. Underemployment therefore tends to rise when aggregate demand is weak.

3.2 Technological change and restructuring

Technological shifts can alter the demand for particular skills and occupations. Automation, digitalization, and organizational restructuring may reduce the need for some tasks while increasing demand for others. Workers whose abilities no longer align with available jobs may become underemployed even when they remain employed.

3.3 Educational mismatch

Educational systems may produce more graduates in certain fields than the economy can absorb at matching skill levels. When qualifications expand faster than high-skill job creation, some workers accept positions that do not require their training. This mismatch can occur after rapid growth in higher education or when local labor markets are narrow.

3.4 Geographic labor market mismatch

Jobs and workers are not always located in the same places. A region may have available employment in one sector while workers with suitable skills live elsewhere. Housing costs, family ties, and commuting barriers can prevent efficient relocation, leaving people in jobs below their potential or limiting their access to more suitable work.

3.5 Sectoral shifts and seasonal demand

Some industries have strong seasonal patterns or experience long-term decline. Agriculture, tourism, retail, and construction can all produce variable demand for labor across the year. Workers in these sectors may face reduced hours during off-peak periods or move into temporary lower-quality jobs between seasons.

4 Measurement and statistics

Measuring underemployment is more complex than measuring unemployment because it involves both objective employment conditions and subjective preferences. Statistical definitions vary by country and institution, which makes comparison difficult. Still, underemployment indicators are widely used to supplement labor market analysis.

4.1 Survey definitions and indicators

Many surveys identify underemployment by asking whether respondents want to work more hours, are available to do so, or work in jobs that do not match their qualifications. Indicators may focus on part-time workers seeking additional hours or on workers whose education exceeds job requirements. The choice of definition strongly affects the resulting estimates.

4.2 Labor force surveys

Labor force surveys are the main source of underemployment data in many countries. These surveys collect information on hours worked, willingness to work more, occupation, education, and job search behavior. Because the data are self-reported, they can reveal labor market conditions that are not visible in payroll records alone.

4.3 Official underemployment rates

Some statistical agencies publish underemployment rates or related measures alongside unemployment rates. These figures may include time-related underemployment, broader labor underutilization indices, or both. Official rates help policymakers assess whether the labor market is improving in a meaningful way or merely reducing open unemployment while leaving many workers underused.

4.4 Limitations of measurement

Underemployment is harder to measure than unemployment because it is partly subjective and because different forms are not directly comparable. A person may accept a job below their skill level for a short period, while another may prefer fewer hours for personal reasons. Such differences complicate classification and interpretation.

4.4.1 Hidden underemployment

Hidden underemployment refers to situations that surveys may miss, such as workers who do not actively state a desire for more hours, or people who have withdrawn expectations after repeated job search failures. It can also include workers whose abilities are underused in ways not captured by standard questionnaire items. This makes true underemployment likely larger than official estimates suggest.

4.4.2 Cross-country comparability issues

Countries differ in labor laws, survey methods, part-time norms, and occupational structures. As a result, one country’s underemployment rate may not be directly comparable with another’s. Definitions of “available work,” “preferred hours,” and “adequate qualification” can also vary, affecting international statistics.

5 Economic and social effects

Underemployment affects not only individual workers but also firms, households, and the broader economy. Its consequences often extend beyond immediate earnings losses. Persistent underemployment can weaken long-term labor market outcomes and reduce the efficient use of human capital.

5.1 Effects on wages and earnings

Workers who are underemployed usually earn less than they would in a fully utilized job. Reduced hours lower total income, and skill-related underemployment may limit wage growth over time. Lower earnings can constrain consumption, saving, and access to credit.

5.2 Effects on productivity

When workers are employed below their skill level, the economy does not fully benefit from their training and experience. Firms may also face lower output if staff are available only part time or are assigned tasks that do not match their strengths. This misallocation can reduce overall productivity.

5.3 Effects on career development

Underemployment can interrupt career progression by limiting experience in relevant roles. Workers may have fewer opportunities to build professional networks, demonstrate competence, or move into higher-responsibility positions. Extended periods of underemployment can make future advancement more difficult.

5.4 Effects on household welfare

Households affected by underemployment may face unstable income, budget stress, and difficulty planning major expenses. The impact can be particularly strong when a family depends on a single earner or when reduced hours coincide with high living costs. Emotional stress may also increase when workers feel they are not using their abilities fully.

5.5 Effects on labor market participation

Repeated underemployment can discourage workers from remaining active in the labor market. Some may reduce job search effort, accept informal work, or leave the labor force temporarily. Others may stay employed but continue looking for a better match, indicating that underemployment can coexist with high participation but poor job quality.

6 Policy responses

Policy responses to underemployment typically aim to raise labor demand, improve matching, and help workers adapt to changing conditions. Effective measures vary by cause and by labor market structure. No single policy can address all forms of underemployment.

6.1 Macroeconomic stabilization

When underemployment stems from weak demand, macroeconomic stabilization can support fuller labor use. Policies that sustain aggregate spending may help firms restore hours and hiring. Such measures are most relevant in downturns, when many workers are involuntarily working less than they would prefer.

6.2 Job creation and demand-side policies

Targeted job creation can reduce slack in sectors or regions with persistent labor underuse. Demand-side policies may include public investment, incentives for hiring, or support for expanding industries. These measures are intended to create openings that better match available labor capacity.

6.3 Training and reskilling programs

Training initiatives can address skill mismatches by helping workers move into occupations with stronger demand. Reskilling may be especially useful where technology has altered job requirements. Programs are generally most effective when they are closely linked to employer needs and actual vacancy patterns.

6.4 Workforce matching and placement services

Job matching services, career counseling, and placement assistance can improve the fit between workers and available jobs. Better information about vacancies, required skills, and local opportunities can reduce frictional underemployment. Public employment services and private recruiters both play a role in this process.

6.5 Hours flexibility and job-sharing measures

Flexible scheduling, voluntary reduced hours, and job-sharing arrangements can help workers combine employment with preferred availability while reducing involuntary underemployment. These measures may also allow employers to distribute work more evenly. When designed well, they can preserve attachment to the labor force during periods of limited demand.

7 Underemployment by group

Underemployment does not affect all workers equally. Age, education, occupation, and work arrangement influence the likelihood of being underemployed. Certain groups are especially exposed to time-related or skill-related mismatch.

7.1 Youth underemployment

Young workers often face a high risk of underemployment because they have limited experience and are still entering the labor market. They may accept temporary, part-time, or low-skill positions while seeking longer-term opportunities. Early underemployment can shape later earnings and career trajectories.

7.2 Graduate underemployment

Graduates may experience underemployment when the number of jobs requiring advanced qualifications does not keep pace with educational attainment. They may work in positions that do not use their specialization or that offer limited advancement. This pattern is frequently discussed in relation to the return on higher education.

7.3 Seasonal and part-time workers

Workers in seasonal or part-time positions are particularly vulnerable to reduced hours. Some choose such arrangements, but others accept them because full-time work is unavailable. Their labor utilization may fluctuate significantly across the year, making income less stable than in standard full-time employment.

7.4 Older workers and displaced workers

Older workers who lose long-held jobs may encounter difficulty finding positions that match their previous pay or responsibilities. Displaced workers can similarly face a period of underemployment while transitioning to new occupations. Age-related skill depreciation, employer preferences, and industry decline can all contribute to this pattern.

Underemployment is closely connected to several other labor market ideas. These related concepts help distinguish different forms of labor slack, job quality, and employment arrangement. Together, they provide a fuller picture of labor market performance.

8.1 Unemployment and disguised unemployment

Unemployment measures people without work who are actively seeking jobs. Disguised unemployment refers to labor that appears employed but contributes little productive output, often because too many workers are assigned to a task. Both concepts differ from underemployment, which usually focuses on employed workers whose skills or hours are not fully used.

8.2 Labor underutilization measures

Labor underutilization measures combine unemployment with underemployment and other indicators of unused labor supply. These measures are designed to capture broader slack than the headline unemployment rate. They are useful for assessing how completely an economy is using available labor resources.

8.3 Informal employment

Informal employment refers to work that is outside formal regulatory, tax, or social protection systems. It can overlap with underemployment when informal jobs are low paid, irregular, or below the worker’s skill level. However, informal employment is defined by job formality rather than by the degree of labor utilization alone.

8.4 Job quality and precarious work

Job quality includes pay, stability, hours, safety, and opportunities for advancement. Precarious work is characterized by insecurity, limited benefits, and weak bargaining power. Underemployment is one dimension of poor job quality, especially when it involves inadequate hours or jobs that fail to use a worker’s capabilities.
