With regard to household expenditures (see Chart IV), households in the lowest income quintile spent 24 % of their income on food, whereas those in the highest quintile spent 12 %. For housing and electricity the lowest and highest quintiles spent 26 % and 12 % respectively, and for healthcare they spent 18 % and 8 %.
再觀察 5 等分家庭的消費支出情形（表四），可以看到 2006 年最低與最高所得家庭的可支配所得中，食品費所佔比例分別是 24％與 12％，房地租與水電費是 26％與 12％，醫療和保健費是 18％與 8％，差距皆達一倍以上。
