In Country Group 2 (“Polarised female labour market behaviour”), where mothers work either full-time or not at all, the probability of working full- rather than part-time increases only when the youngest child is aged between 6 and 10 years old. And in countries where mothers often work part-time (“Women in long-term part-time work”, Country Group 1), the probability of working full-time increases only when the youngest child is 11 to 15 years old, as is also the case in countries with a relatively narrow gender gap in working hours (e.g. France and the Nordics, Country Group 4). In Eastern European countries (Country' Group 3), the number of children in a household does not appear to have a significant impact on the likelihood of an employed mother working full- rather than part-time.
