[4] The 30th Assembly district is contained within the Wisconsin portion of the Minneapolis-Saint Paul Metropolitan Area.
[6] The 1982 court-ordered redistricting briefly moved the 30th district to eastern Waukesha County.
The 1983 redistricting act moved it back to western Wisconsin, but in a much smaller geographic space than 1972, comprising just Pierce County and part of southwest St. Croix County, including the cities of Hudson and River Falls.
As population grew in the two cities, the 1992 court-ordered plan removed more rural parts of northeast Pierce County and central St. Croix County, but maintained the core population of the district.
Act 43) also continued with Hudson and River Falls as the core of the district, but removed most of the rest of Pierce County and shifted the district north to contain more of St. Croix County.
