In the United States the clearance rates 2018 for motor-vehicle theft and burglary were less than 15 percent. For theft and property crime, the clearance rates were less than 20 percent. For robbery, the clearance rate was just over 30 percent and for arson, the clearance rate was less than 25 percent.

In 2010 in Canada the clearance rates for theft over $5000 and theft of a motor vehicle were less than 15 percent. For Arson and breaking and entering, the clearance rates were less than 20 percent. For theft under $5000 the clearance rate was about 21 percent.
