Social order is always a major concern of any region. It can be broken by war or natural disasters but mostly it is broken by behavior that violates legal regulations in the region. As a result，the government needs to establish mechanisms like police and corrections to maintain social order. From 1999 to 2007，the number of the criminal cases and the population in Macao both increased，but the growth rate was different for many years. For example，the increase of the crime rate in 2007 was almost four times that of the increase in the population. Property crime constituted more than half of the criminal cases for many years. On the other hand，the personnel in law enforcement agencies have also increased. But the increase was mainly in the areas of corrections rather than policing and judicial officials，which places more pressure on maintaining social order in general. In the future，more studies have to be done in crimes related to gaming.
