By investigating how locally available early childhood education and care quality relates to maternal employment choices, this study extended the literature which has mostly focused on the importance of day-care availability or costs. We provided differentiated analyses by the youngest child's age and for West and East Germany to examine moderating influences of varying day-care supply and work-care cultures. The empirical analysis linked the Socio-Economic Panel and the 'Families in Germany'-Study for 2010 and 2011 (N=3,301 mothers) with regional structural quality data. We used regression models of employment status and work hours changes, respectively. In East Germany, mothers with a child aged under three years who lived in districts with smaller day-care groups were more likely to be employed and to extend their work hours. In West Germany, the negative association of child-teacher-ratios with maternal employment was marginally significant. For mothers with older children, day-care quality was unrelated to employment.
