In the Bolivarian Republic ofVenezuela, Chile, Costa Rica, Honduras and Mexico, its importance diminished steadily during the decade under consideration, reflecting improved provision of household waste treatment methods. However, the contribution of the drinking water dimension to total child poverty was found to have increased in 11 countries. A notable case is Costa Rica, where it increased from 20.8% in 2002 to40% in 2011 (see table 11.8). In this country the drinking water dimension contributed even more to extreme poverty, rising from 42.8% in 2002 to 67.6% in 2011, as table II.7 shows. In the case of Jamaica, it shows some of the deprivations for which data are available.
