Rock County residents appear to be taking the census seriously. Regional coordinator Jerry Huffman says Rock County is well ahead of the national average of 62% of respondents filling out the census on-line. He says Rock County is approaching 74 %. Huffman urges residents to fill out the census on-line because each completed form represents $1500 in federal aid for the area. He also says those who don’t fill out their form, will get a knock on the door from a census taker starting early next month.
