The proportion of private kindergartens reporting 5% or more children with PBEs increased from 9% (2000–2001) to 34% (2013–2014), followed by a small decrease in 2014–2015 (31%). Overall, 93.7% (565/605) of kindergartens sampled in 2014–2015 had data available. Very high PBE levels (>20%) were seen among secular and non-Catholic, Christian kindergartens but not Roman Catholic, Jewish or Islamic kindergartens. However, the majority of schools at all tuition levels had fewer than 5% of children with a PBE. Kindergartens with an annual tuition of $10,000 or more were over twice as likely to have 20% or more children with PBEs than kindergartens with a lower tuition (p < .01). Additionally, the conditional admission proportions for kindergartens with tuitions of $10,000 or more were 39% compared to 22% for less expensive kindergartens (p < .01). Only about half of all private kindergartens had 95% coverage of the MMR (49%) and pertussis-containing vaccines (51%).
