The indicator measures the share of people aged 25 to 64 who stated that they received formal or non-formal education and training in the four weeks preceding the survey (numerator). The denominator consists of the total population of the same age group, excluding those who did not answer the question 'participation in education and training'. Adult learning covers job-related and non-job-related formal and non-formal learning activities. It usually refers to learning activities after the end of initial education. Data stem from the EU Labour Force Survey (EU-LFS).

The gender gap in part-time employment is defined as the difference between the share of part-time employment in total employment of women and men aged 20-64. The indicator is based on the EU Labour Force Survey.

The indicator measures the difference between average gross hourly earnings of male paid employees and of female paid employees as a percentage of average gross hourly earnings of male paid employees. The indicator has been defined as unadjusted, because it gives an overall picture of gender inequalities in terms of pay and measures a concept which is broader than the concept of equal pay for equal work. All employees working in firms with ten or more employees, without restrictions for age and hours worked, are included.
