The share of children under the age of 3 enrolled in ECEC is on the rise in most countries and has increased on average from 25% to 31% between 2010 and 2016 (Table B2.1b). This is particularly marked in many European countries, as a result of further stimulus by the 2010 objectives set by the European Union (EU) at its Barcelona meeting (to supply subsidised full-day places for one-third of children under the age of 3 by 2010) (OECD, 2017(4]). More globally, the rise in ECEC provision over the last decades has greatly contributed to the increase in women’s participation in the labour force, particularly for mothers with children under age 3. Countries with higher enrolment rates of children under age 3 in 2016 tend to be those in which the employment rates of mothers are highest ([OECD, 2018,1]] [OECD, 2018(7]], Figure B2.1). In countries such as Norway, for instance, not only do more than half of the children below age 3 attend ECEC services, but they also attend programmes integrated within the education system from below age 1 until the beginning of primary school.
