Madison’s population will still be less than half that of Milwaukee in 2040, according to official population projections by the University of Wisconsin-Madison from 2013. The 2040 projections estimated a Madison population of 281,150, compared with 627,400 for Milwaukee.
A regional study from 2022 projected larger growth figures for Madison, with estimates of 306,521 for 2035 and 345,675 for 2050. That’s still much smaller than the state’s largest city.
