Several communities in the Phoenix area are currently conducting a Special Census. My understanding is that the Census Bureau has made some changes to this process, all Special Census' are conducted door-to-door rather than using a mailing. When we first started looking into it there were very few communities who had gone through this process, mostly very small communities. Because the Census is door-to-door, it is costly compared to years past. I'd be happy to share what we have with you. You can e-mail me at firstname.lastname@example.org.
