Currently, Statscan provides annual data based on three different measures of low income – the LICO AT, the LIM AT and the MBM. (See CANSIM Table 206-0041 for detailed data on poverty using these measures.) LICO estimates are also presented on a pre tax basis but these are seldom used. While the three measures in use today are not described as poverty lines, they are generally used as such, and they all allow for assessment of levels and trends in a disaggregated fashion.

The key point is that the conceptual and measurement differences between LIM and the MBM result in significant differences in rates of low income for important sub populations. It is important to have both measures to account for this complexity.

… the LIM and the MBM are conceptually different measures, both of which provide useful and important information for analysts and policy makers. We need both to get a handle on overall low incomes and trends in different populations.
