3. Résumé

«We find, first, that there is considerable inequality of family income among Canadian children - a child at the 90th percentile has a material standard of living that is, on average, about five times that of a child at the 10th percentile. Second, we find persistence of income position as children grow up. […] A concern about inequality suggests that it is intrinsically unfair if one child is very affluent while another is very poor, particularly when inequality is persistent. Evidence of full socio-economic gradients in children’s health and educational outcomes suggests that persistent inequality during childhood is likely to translate into inequality during the adult years. Perhaps paradoxically, while we find evidence of persistence of position in the income distribution for some children, we also find more exposure to both low and high income than is indicated in cross-sectional data. […] We find that 25 percent of all observed inequality among all the children in our sample is attributable to year-toyear variations in family income experienced by any given child; 75 percent results from inequality of longrun average income across children.» (p. 122-123) Ce rapport fournit des comparaisons interprovinciales et contient donc plusieurs données pour la situation québécoise.
