2010 Census forms started arriving in mailboxes Monday. The census count determines how congressional district lines are drawn and the amount of federal funding awarded to states. Here in New York, Sen. Kirsten Gillibrand and New York Secretary of State Lorraine Cortes-Vazquez urged all New York residents to fill out the forms, including undocumented immigrants. The officials said New York City lost millions of dollars in federal and state funding over the past decade because only 55 percent of city residents mailed in census forms ten years ago. In Texas, officials say over 370,000 Texans were uncounted in the 2000 Census resulting in the loss of about $1 billion in federal funds.
