Abstract: The study estimates the dynamics of socio-economic determinants of crime in Nigeria from 1981-2005 using an error-correction model. The exclusive socio-economic determinants are population, literacy, unemployment, inflation and income. The study analysed the long-run causality between security or crime and discomfort applying the error-correction based, Granger causality technique and dynamic error-correction method. The results revealed that unemployment is the most important determinant of crime in Nigeria. The evidence that insecurity Granger causes discomfort is also established.
