Pros
There is a good rate of pay and an opportunity to work within communities representing the federal government. You are part of a very important effort correctly count the population so that local areas can receive the correct allocation of federal grant funding and appropriately proportion representation in the House of Representatives.
Cons
The worst thing about the Census is its very nature: temporal. There is little knowledge among mid-level management about the Bureau's plans on a specific item until the day the project is set to begin -- or days after that. Employees are constantly being told conflicting bits of information. Even after the interview process, there is little knowledge of when an assignment will be completed and hourly employment will end. Change in this organization is abrupt and wholly destructive.
