For the full network, Zhong became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Copiapó fluctuated in connectivity and Yangzhong became progressively more disconnected. Zhong and Copiapó have been converging in their street-network character since 1975.
