Figure 2

Lorenz curves for caries distribution in two 3-year-old groups, illustrating deviation in caries skewness. Footnote: Each point on these Lorenz curves denotes the proportion of the population (y-axis) responsible for the proportion of the total burden of caries lesions (x-axis). The arrows indicate that 6% of a western native (WN) of 3 year-olds and 23% of an immigrant group (IM) of non-western origin, 3 year-olds, carry about 75% of the total caries burden. This graph is adjusted from an article based on this survey [48] .
