 There are few studies on the affordability of water and sewer bills in Latin America.The Pan-American Health Organization (PAHO) analyzed multi-purpose household surveys conducted between 1995 and 1999 in 10 countries to assess the share of household income spent on water supply services.These data show that the expenditures on water vary between 0.4% of total expenditures in rural Panama to 3.0% in Kingston, Jamaica.
