The indicator tries to compares the distribution of care responsibilities of mothers and fathers. A lower employment rate of mothers as compared to fathers indicates that mothers more frequently stop work due to family responsibilities and may potentially face disadvantages regarding different aspects of quality of employment (e.g., income, career prospects). The comparison of mothers and fathers to women and men without children under compulsory school age gives an impression of the share of mothers and fathers who resign from employment for a certain time in order to take care of their family, which will potentially be accompanied by disadvantages.
