Income inequality among Saskatchewan families has increased rapidly since 2000. As the Saskatchewan economy has became more prosperous, upper income families have benefited most from economic expansion. The share of aftertax income received by the twenty per cent of families with the highest incomes was over forty per cent in 2006, the largest share in thirty years. In contrast, the share of after-tax income for the twenty per cent of families with the least income declined to just over six per cent (6.2%), their smallest share in thirty years.
