The BU ratio is a common comparison of two data points. The B stands for beneficiaries and the U stands for unemployed. As I was explaining earlier, they're different things, so the number of people who are on EI is not the same as the count of people who are unemployed. There are perceptions otherwise, but they are different things. The unemployed count is bigger than that of the number of employment insurance beneficiaries, and it always has been. For various reasons, not all unemployed people qualify for EI. The BU ratio is sometimes used to evaluate the success of the EI program. It's not our business at Statistics Canada to be doing that or assessing that program.
The beneficiary-to-unemployed count is a simple measure. One of the reasons I understand that HRSDC contracts us to run the Employment Insurance Coverage Survey is that they want to know more than just what's in the BU ratio. So the numbers I was giving your about potential eligibility and the reasons eligibility differs from men to women come from that survey, and it's that survey that provides you with a more in-depth understanding of why people don't qualify.
So I would turn to that survey to get an understanding of why there are differences in EI receipt among men and women, and I would try to stay away from the simple BU ratios.
