Is Ningbo an immigrant city or a rural area?

Born in Shanghai, a native of Ningbo, a native of Ningbo, is a native of Shanghai. Shanghai is an immigrant city, and most of the Shanghai people over three generations are immigrants. Take me for example. My father is from Jiangyin, Wuxi, Jiangsu, and my mother is from Zhenhai, Ningbo, Zhejiang. I was born in Shanghai, so I am a native of Shanghai.
