For the full network, Natore became progressively more disconnected, while Zhaishang grew more disconnected from 1975 through 1991-2005, then improved and Perinthalmanna became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Natore had a more connected network than Zhaishang in 1975 but the two have since reversed their relative ranking.
