    Abstract: Monitoring crime rate with statistical tools and modern scientific and technological methods
determine the safety index or otherwise of a geographical area. This study explores the use of GIS classifications
and mean and range charts for monitoring crime rates in a geographical area. The standard charts were
constructed using the crime rates of the median levels of crimes from GIS classification of Katsina state crime
data. The historical mean can be use to monitor the levels of the crimes in the future period.
