These California communities could be the next Paradise. Is yours one of them? A lot of Californians live in places that could be quickly destroyed by wildfire. To estimate how many, McClatchy used two primary sources: The U.S. Census Bureau and Cal Fire maps showing "very high fire hazard severity zones." The analysis used block-level data from the 2010 Census. Blocks are the smallest level of census geography. McClatchy calculated the center point of each block in the state then calculated how many of those points fell within very high fire hazard severity zones. Finally, McClatchy matched up blocks in very high hazard safety zones with census files showing the boundaries of each city and unincorporated town in the state.
