| Abstract: | The minimum cost of an adequate diet, following food preferences, is estimated for families in ten South American cities in five countries, allowing for household composition by age and sex. The ratio of actual expenditure on food and beverages to this normative expenditure is then used to rank families in six classes, of which the bottom two correspond to absolute poverty, or to actual expenditure less than the estimated minimum. Three questions can then be explored: which families appear to be poor, on this measure? how do such families allocate their spending toward other items such as housing? and, does this indicator of poverty classify families in much the same way as other proposed measures? The results suggest some under-reporting of food spending in the poorest class, but otherwise the ratio of reported to normative spending gives good results, free from the errors in other parts of the budget and the arbitrariness of indicators which depend on socially-defined rather than physiological “needs.” Poor families tend to be large, with many children; to have many dependents per income recipient; to have male working members other than the head; to suffer unemployment of members other than the head; to have relatively low levels of schooling; and to show high density in housing. Even quite poor households spend appreciable amounts on housing and on education, while not satisfying all food needs; both kinds of spending increase rapidly as food requirements are met. There are no consistent relations between poverty and type of employment or the share of income attributed to the head. The data refer to 1966–69 and are highly comparable; all monetary estimates are in dollars of equal purchasing power. |
