Introduction

In contemporary economies, the labour market functions not only as a key mechanism for matching workers with jobs but also as a crucial factor in ensuring macroeconomic stability and individual well-being. Its strategic role derives from its integration with other market systems, including finance, goods, and services. Employers rely on human capital to foster innovation and productivity, while individuals depend on employment to secure economic stability and personal fulfilment. The dynamic character of the labour market reflects ongoing changes in educational attainment, technological advancement, and the evolving expectations of both employers and jobseekers.

Research hypothesis: the changes that have occurred on the labour market in recent years are reducing demand from businesses for employees with higher education.

Intensity of labour demand – visualisation

The charts below illustrate selected trends in the intensity of labour demand (ILD3) between 2010 and 2023, with particular focus on education levels and occupational structures based on the ISCED and ISCO-08 classifications. All figures have been independently developed by the authors using original data processed with the ILD3 indicator methodology.

The following tables present linear trends in labour demand intensity (ILD3) across major occupational groups (ISCO-08) in selected EU countries, classified by education level based on the ISCED framework. The data cover the period from 2010 to 2023. A plus sign (“+”) indicates a rising trend in labour demand within a given occupational group, a minus sign (“−”) represents a declining trend. This structure allows for a comparative overview of how qualification levels relate to labour demand dynamics across the European labour market.

ISCO-08 groups: 1 – Managers, 2 – Professionals, 3 – Technicians and associate professionals, 4 – Clerical support workers, 5 – Service and sales workers, 6 – Skilled agricultural, forestry and fishery workers, 7 – Craft and related trades workers, 8 – Plant and machine operators and assemblers, 9 – Elementary occupations.

Research methodology

The methodology of this study is based on the construction of a composite indicator designed to measure the intensity of labour demand (ILD) in EU countries between 2010 and 2023. The approach relies on Eurostat data related to employment levels, total hours worked, and average working hours, combined with adjustments for absenteeism and educational structure.

The initial formula for measuring ILD was based on total working hours and is expressed as:

ILD = P × H × D

where:
P – number of people employed in the economy,
H – average number of hours worked per day,
D – number of working days in a year.

In the next phase, the indicator was refined by incorporating average absence rates (A) among workers, resulting in a new formula:

ILD2 = P × H × D × (1 − A)

where:
A – average percentage rate of absence from work in a given year.

To capture the educational and occupational structure of the workforce, the final indicator (ILD3) uses disaggregated data by ISCED education levels and ISCO-08 occupational categories. The adjusted formula is:

ILD3 = PEC × H × D × (1 − A)

where:
PEC – number of people employed by education level (ISCED) and occupation (ISCO-08),
H – average number of hours worked per day,
D – number of working days in a year,
A – average absence rate.

To analyse relative change over time, ILD3 was expressed as a fixed-base index with 2010 as the base year (y₁), using the formula:

ILD3t / ILD32010

All ILD3 values were calculated for 24 EU countries (excluding Luxembourg, Slovakia, and Greece) using ISCO-08's 9 major occupational groups and ISCED education levels. Armed Forces Occupations were excluded due to data unavailability.

Conclusions

The conducted analysis confirmed that labour markets in EU countries between 2010 and 2023 exhibited clear trends in the intensity of labour demand (ILD3), differentiated by level of education and occupational structure. The indicator made it possible to assess long-term shifts in demand across ISCO-08 occupational groups and ISCED education levels. Its application to data from 24 EU countries revealed a strong upward trend in demand for workers with higher education, observable across nearly all occupational groups regardless of ISCO-08 classification.

Interestingly, even in occupational groups traditionally not requiring high-level qualifications—such as Elementary Occupations (ISCO 9)—there was an increase in labour demand for individuals with higher education. This suggests that employers increasingly value broader competencies, adaptability, and the potential for internal mobility that higher education brings, regardless of the job's formal skill level. In contrast, individuals with secondary education (ISCED 3–4) were more frequently subject to declining trends. Negative or indeterminate labour demand trajectories affected approximately 27% of the observations in this group, while only 4% of observations for higher education graduates indicated a declining trend.

These results offer clear evidence in support of a structural shift in labour market preferences towards more highly educated workers. Acquired skills, greater adaptability, and the ability to work in technologically advanced environments strengthen the labour market position of this group. Consequently, the research findings contradict the initial hypothesis that the changes that have occurred on the labour market in recent years are reducing demand from businesses for employees with higher education. On the contrary, the results indicate a steady and widespread increase in demand for this category of workers across all major occupational areas.
