For example, among European countries, the proportion of mothers in fulltime work varies from 8% in the Netherlands to 77% in Slovenia. In addition to country-specific factors, such as public child care support (Box 4.3), there are also individual and family-specific reasons why women choose to work full- or part-time. Changes in labour markets have been powerful factors in growing female labour force participation in OECD countries, particularly the development of the services sector and the expansion of part-time work, which have enabled a greater proportion of women to work and keep working after they start to have children.
