"Police and researchers have long focused on crime at the neighborhood and precinct levels. More recently, law enforcement agencies have been finding that identifying and focusing on 'hot spots' is a fruitful approach to crime prevention. A new study shows that it may be even more effective to take such approaches down to the level of individual city blocks. Researchers studied block-by-block crime incidents in Seattle from 1989 to 2004. They identified 24,023 'street segments' (the streets at both sides of an intersection) and 1,697,212 crime reports. They found that crime rates declined in Seattle as a whole during the study period (as they did in many American cities) but that at the micro-level of city blocks, crime trends could vary from city wide and even neighborhood trends."
