I understand why it's important to track some things seasonally (profit/loss for a ski resort, beach resort.. etc), but unemployment adjusted seasonally seems to be a way to make the numbers look better than they are - it certainly doesn't keep those people paying their mortgage.
If you lose your job because it's winter (landscaper, beach bartender) or summer (ski lift operator, hockey ref) I see no reason to not count that in the same way as a loss because of other circumstances.
Another issue I have with their 9.7% (or 10%, whatever it's supposedly at right now) is that it doesn't include people who have given up looking. This is essentially the government 'giving up' on these people, removing them from their statistics so they don't make them look as bad.
Why not just release the real numbers more openly including seasonal layoffs, people who have had their benefits run out, and those who were previously employed but can no longer find work?
