These statistics should also be interpreted with caution, as expenditure is also influenced by the extent to which these indicators cover private settings and private expenditure, by the decision of some countries to consider some ECEC programmes outside the scope of the ISCED 2011 classification, or by the impossibility of providing reliable statistics to international organisations. For example, the absence of data on private expenditure and private institutions in Brazil and Switzerland is likely to understate the true level of expenditure and enrolment in early childhood education programmes (ISCED 0), and may affect the comparability of the data with other countries. Inferences on access to and quality of ECEC should therefore be made with caution. Consequently, early childhood educational development programmes (ISCED 01) are not reported in some OECD countries, namely Belgium (French Community), the Czech Republic, France, Ireland, Italy, Japan, Luxembourg, the Netherlands, Poland, Portugal, the Slovak Republic, and Switzerland, or data are missing in some countries, such as the Flemish community of Belgium and the United States.
