We've looked at this issue from every angle, obviously because it's a fundamental issue. The mandatory nature of the census actually ensures that there's a budget attached, not to enforce but to promote compliance and inclusion. That budget actually helps people go out and do that community engagement and get people to comply and help them understand what it's being used for. If it's just a voluntary survey, you're not necessarily going to have that budget attached to it to do that work.
