Data collation revealed that 69.2% (243) of the rural population were menstruating, while 70.1% (356) of the urban population were menstruating. Mean ages of menarche were 13.19±1.32 years and 14.22±1.47 years for urban and rural areas respectively .A statistically significant lower mean menarchial age was observed in urban area girls, compared to their rural counterparts. Girls from families of high socio-economic class has significantly lower mean menarchial age in both urban and rural area. The mean age of menarche was significantly higher in girls involved in vigorous sporting activity in rural areas compared to their non-sporting counterparts. Urban school girls attain menarche earlier than those in rural area. High socio-economic class and vigorous sporting activity can be predisposing factors to low and high age of menarche respectively. There is need for redefinition of high socio-economic class in Nigeria.
