Figure 5.1 Twin Cities population by zone, 1860-2010.pdf

Note: A long-term chart of population growth in concentric zones of the region – the central cities, the remainder of Hennepin and Ramsey Counties, the outer five counties of the seven-county region, and the twelve contiguous “collar counties” in Minnesota and Wisconsin – shows that the central cities captures the vast majority of population growth through the 1930s. Their population declined from the 1950s through the 1980s, marginally increasing in the early 2000s. The 1940s were a point of inflection – thereafter, all population growth occurred outside the central cities in the extremities of Hennepin and Ramsey, and also in Anoka, Carver, Dakota, Scott, and Washington Counties. After the 1970s, population growth has accelerated in the Minnesota and Wisconsin collar counties as well.https://ir.lib.uwo.ca/shapingthemetropolis/1010/thumbnail.jp
