These data show' that OECD countries differ considerably not only in terms of inter-regional disparities in average incomes, but also in terms of spatial concentration of income inequalities. Equality of opportunity requires that socio-economic prospects of each individual are not affected by factors beyond their control, such as their place of birth (Roemer, 1997). People-centred policies should thus reflect the interplay of locational and individual level determinants of well-being. Data on income inequality within regions might capture better than national data the effects of perceived distribution inequities on subjective well-being and on human capital investments. Individuals may in fact assign different importance to the income inequalities they experience in their local living context when assessing their own w'ell-being and forming expectations about returns of education and skills.
