We have some detail on the working poor. This is an issue, because it's not just low income. The working poor tend to lack the types of services that other workers are more likely to get, such as dental plans and disability insurance. So there is a compounding effect. It's not just the income they don't have; it is also the lack of these benefits and services that support them.
In terms of what industries they're in, I'll just have to look at some material. We've done a fair amount of work in our department on the issue of the working poor. We could certainly provide you with the results of that research. It is an issue within the department.
