Variations exist in the targeted age groups, the governance of centres, the funding of services, the type of delivery (full-day versus part-day attendance), as well as the location of provision, either in centres/schools or at home (OECD, 2017(4]). The distinction between these two categories is explicitly shown in Figure B2.1 and in Table B2.4. Informal care services (generally unregulated care arranged by the child’s parent either in the child’s home or elsewhere, provided by relatives, friends, neighbours, babysitters or nannies) are not covered in this indicator (see Definitions section at the end of this indicator for more details). This average hides great differences across countries. The length of parental leave also influences the age at which children enrol in ECEC services.
