Beginning in March, Pinellas County residents will receive their 2010 Census forms in the mail. The census data are important because they are used in determining congressional and legislative districts as well as determining funding for schools, housing, roads, and more. The form is shorter this year than in 2000, and is comprised of only 10 questions. Residents are asked to fill out the form and return it by U.S. mail. If forms are not received by April 1, 2010, census workers will begin visiting those households that did not return their forms. These visits will occur from April through July, 2010. Federal law mandates that individual responses are confidential.
