According to surveillance principles of Zhejiang Province, Ningbo city were stratified into 3 strata： one urban and rural areas I and ]I. Results A total of 503 incidence cases and 123 death ones were reported in Ningbo, 2013.

With age increasing, the age-specific incidence was shaped like the reversed letter ＂U＂ and the groups with high incidence aged between 30 and 69 years. The mortality of cervical cancer increased with age （Trend x^2 = 87.13,P〈0.01）. The incidence and mortality of cervical cancer were higher in type II rural area than that in urban and type I rural area.
