Residential independence and incorporation into the labour market are two fundamental aspects of the transition of young people to adulthood, and gender differences have been observed in both. This study aims to determine the reasons behind the gender gap seen in young adults leaving their parental home and in finding paid employment. We analyse both the decisions of residential independence and employment jointly, for the sample of men and that of women. We separate the influence of observed factors from the influence of unobserved factors or preferences on the gender gap using decomposition techniques. The analysis is carried out for two points in time; this temporal comparison can help demonstrate whether the recent social changes experienced have modified the behaviour patterns of young people. Our findings indicate that, in accordance with the trend observed in recent decades in Europe, there is a convergence between men and women in the residential independence of young adults in Spain. However, in the labour market, there is still much to be done to reduce the gender gap. One recommendation arising from our study would be to promote policies which further improve the conciliation of family and work life, since this could reduce female labour abandonment associated with starting a family or motherhood.
