From 1975 until 2004, the weighted votes didn't change at all, because presumably it was decided that not much had changed in Hudson's population numbers so it wasn't necessary to recalculate the weighted vote.
After the 2000 census, the weighted vote was recalculated, with some significant changes. The big losers were the First Ward and the Fourth Ward, with the votes of their aldermen dropping from 188 to 94 and 184 to 94 respectively. The winners were the Second Ward, whose aldermen gained 24 votes each, and the Third Ward, whose representatives gained 46 votes each.
Now, after the 2010 census, there are two significant changes in the weighted vote. The big loser is the Third Ward, whose aldermen now have 86 fewer votes each. The big winner is the Fifth Ward, whose aldermen have gained 86 votes each.
