along with a projection for employment not
accorded dominant or subdominant industry status.
2. The 1990 population of the Region was about
1,810,400, an increase of about 569,800, or 46 per-
cent, over the 1950 population of about 1,240,600.
The population of the Region increased significantly
during the 1950s and 1960s, with increases of
27 percent and 12 percent, respectively, occurring
during those decades. During the 1970s and 1980s,
however, the population of the Region increased
by only 3 percent. Over the entire period from 1950
to 1990, the population of the Region increased
by about 46 percent, compared to 42 percent for
Wisconsin and 65 percent for the United States.
The greatest rates of population growth over the
period from 1950 to 1990 occurred in Ozaukee,
Washington, and Waukesha Counties, with popula-
tion increases of 212 percent, 181 percent, and
255 percent, respectively.
Varying rates of population growth have resulted
in significant shifts in population among the seven
counties. Most notably, the Milwaukee County
share of the regional population decreased from
about 70 percent in 1950 to about 53 percent in
1990, and the Waukesha County share increased
from about 7 percent in 1950 to about 17 percent
in 1990.
The urban-rural composition of the Region's popu-
lation, like that of most metropolitan regions in the
United States, has become increasingly urban-as
measured in terms of urban and rural place-of-
residence data enumerated in the U. S. Censuses of
Population. The population of the Region was
approximately 76 percent rural and 24 percent urban
in 1850. By 1910, this relationship had reversed to
24 percent rural and 76 percent urban. In 1990, the
population of the Region was 87 percent urban and
13 percent rural.
3. Under a high-growth scenario, the resident
population of the Region would increase by about
556,600 persons, or about 31 percent, from
1,810,400 persons in 1990 to 2,367,000 persons
by the year 2020. Under an intermediate-growth
scenario, the resident population of the Region
would increase by about 267,500 persons, or about
15 percent, to 2,077,900 persons by the year 2020.
Under a low-growth scenario, the resident popula-
tion of the Region would increase by about 114,600
persons, or about 6 percent, to 1,925,000 persons

by the year 2020. Under the high-growth projec-
tion, Milwaukee County would experience the
largest absolute increase in population; under the
intermediate- and low-growth projections, Wauke-
sha County would experience the largest absolute
increases in population.
4. The number of households in the Region in 1990
was about 676,100, an increase of about 321,600, or
91 percent, over the 1950 level of about 354,500.
The number of households in the Region increased
significantly during the 1950s, 1960s, and 1970s,
with increases of 31 percent, 15 percent, and 17 per-
cent, respectively, occurring during those decades.
During the 1980s, however, that rate of growth
slowed to about 8 percent. Over the entire period
from 1950 to 1990, the number of households in
the Region increased by about 91 percent, compared
to 88 percent for the State and 117 percent for the
Nation. The greatest rates of growth in the number
of households over the period from 1950 to 1990
occurred in Ozaukee, Washington, and Waukesha
Counties, with increases in households of 290 per-
cent, 251 percent, and 349 percent, respectively.
Varying rates of growth have resulted in significant
changes in the proportional distribution of total
households in the Region among the seven counties.
Most notably, the Milwaukee County share of
regional households decreased from about 70 per-
cent in 1950 to about 55 percent in 1990, and the
Waukesha County share increased from about
7 percent in 1950 to about 16 percent in 1990.
The number of households in the Region, State, and
Nation increased at a rate nearly double that of the
population between 1950 and 1990. Between 1950
and 1990, the average household size in the Region
decreased from 3.36 to 2.62 persons, or by
22 percent. In 1990, all of the counties in the Region
exhibited average household sizes of less than 3.00
persons per household.
5. Under a high-growth scenario, the number of
households in the Region would increase by about
229,000, or about 34 percent, from 676,100 house-
holds in 1990 to 905,100 households by the year
2020. Under an intermediate-growth scenario, the
number of households in the Region would increase
by about 151,000, or about 22 percent, to 827,100
by the year 2020. Under a low-growth scenario,
the number of households in the Region would
