From the AJC “Missed by the census? More forms on the way”:
Officials with the tiny DeKalb County city of Pine Lake said last week that none of the community’s residents had received a form. Those residents receive mail at post office boxes because there is no residential mail delivery. The census bureau recently decided to send forms to post office boxes after April 12.
