Investigation of the Causes of Rising Crime Rates in Port Harcourt City

Port Harcourt has among the highest violent crime rates of any Nigerian city, and understanding the confluence of factors driving this elevated criminality is essential for both law enforcement planning and social crime prevention investment. This study investigated the primary causes of rising crime rates in Port Harcourt City, Rivers State, South South Nigeria. A descriptive survey design was employed with questionnaires administered to 280 residents from Port Harcourt Municipal and Obio-Akpor Local Government Areas, stratified by age, gender, and residential location. The survey assessed perceived crime drivers, personal victimisation experience, community social capital, and satisfaction with security service delivery. Ordered logistic regression was applied to rank and analyse crime drivers. Results identified unemployment and youth idleness as the highest-rated crime driver (mean score 4.3 out of 5), followed by drug and substance abuse (4.1), breakdown of family values (3.9), poor governance and endemic corruption (3.8), and inadequate street lighting and environmental design (3.4). Personal victimisation in the preceding 12 months was reported by 48.9 percent. Police response time was rated as poor by 79.3 percent. Community neighbourhood watch participation was reported by only 22.1 percent. The study recommends an integrated Port Harcourt crime reduction strategy addressing both situational prevention (environment design, surveillance) and social prevention (employment, youth programming, family support).
