This divergence in our 2015 report was driven by the settings of current policy both at the federal and subnational levels. Much of the pressure from population aging is limited at the federal level to its elderly benefits, whereas at the provincial level there's a broader impact from population aging on, let's say, health care spending, which is a significantly larger share of the economy than elderly benefits. Population aging combined with what we call excess cost growth—the growth in health spending that we can't explain by fundamental drivers, such as economic growth, population aging, or inflation—are the two factors contributing to the pressures on subnational governments.
