1985 and 2010, Milwaukee County's share of the
regional population would decrease from about
54 percent to about 49 percent under the low-
growth decentralized plan, to about 48 percent
under the high-growth centralized plan, to about
44 percent under the intermediate-growth decen-
tralized plan, and to about 40 percent under the
high-growth decentralized plan. Under the
recommended land use plan, Milwaukee County
would account for about 49 percent of the
regional population in 2010. Conversely, Wauke-
sha County's share of the regional population
would increase from about 16 percent in 1985 to
about 20 percent under the low-growth decentral-
ized and high-growth centralized plans, to about
22 percent under the intermediate-growth decen-
tralized plan, and to about 23 percent under the
high-growth decentralized plan. Under the
recommended plan, Waukesha County would
account for about 19 percent of the regional
population in 2010.
Similar information regarding the number and
distribution of households in the Region antici-
pated under the alternative futures plans and
the recommended land use plan is presented in
Table 161 and Figure 82. As indicated in
Table 161, between 1985 and 2010 the number of
households in the Region would increase by
about 202,600, or about 32 percent, to about
846,400 under the high-growth decentralized
plan; by about 212,500 households, or about
33 percent, to about 856,300 under the high-
growth centralized plan; by about 109,000, or
about 17 percent, to about 752,800 under the
intermediate-growth decentralized plan; and by
32,300, or about 5 percent, to 676,100 under the
low-growth decentralized plan.' Under the
1 The number of households anticipated under
the high-growth centralized plan differs from
that anticipated under the high-growth decen-
tralized plan even though the plans are based on
the same design year regional population level.
This situation is due to the differences in the
anticipated distribution of population under the
respective plans combined with anticipated
differences in household size within the Region.
The high-growth decentralized plan envisions
fewer households than the high-growth central-
ized plan because it envisions higher population
levels in outlying areas, where household sizes
are typically larger, and lower population levels
in older urban areas, where household sizes are
typically smaller.

recommended plan, the number of households in
the Region would increase by 130,500, or
20 percent, to about 774,300 in the year 2010.
Differences in relative rates of growth in popu-
lation and households, particularly evident for
the intermediate-growth decentralized plan, low-
growth decentralized plan, and recommended
plan, are attributable, for the most part, to
anticipated changes in household types and
related changes in household sizes, including a
continued increase in the relative proportion of
single-parent and single-person households.
The change in the relative distribution of
households among the seven counties envisioned
under the alternative futures plans and the
recommended plan is indicated in Table 162.
These changes generally parallel the anticipated
changes in the relative distribution of the
population described above, with Milwaukee and
Waukesha Counties being the most affected.
The population density of the developed urban
area of the Region would continue to decline
under each of the alternative futures plans as
well as under the recommended plan. As indi-
cated in Table 163, between 1985 and 2010 the
urban population density would decrease from
about 3,600 persons per square mile to about
3,100 persons per square mile under the high-
growth centralized plan, to about 2,900 persons
per square mile under the high-growth decentral-
ized plan, and to about 2,600 persons per square
mile under the intermediate-growth decentral-
ized and low-growth decentralized plans. Under
the recommended year 2010 regional land use
plan, the urban population density would be
about 2,800 persons per square mile in the
year 2010.
Employment Distribution
Employment levels anticipated under the alter-
native futures plans and the recommended land
use plan are presented by county in Table 164
and Figure 83. Under both the high-growth
decentralized and high-growth centralized plans,
total employment in the Region would increase
by 380,000 jobs, or about 44 percent, from about
872,000 jobs in 1985 to about 1,252,000 jobs by
the year 2010. Under the high-growth decentral-
ized plan, Waukesha County would experience
the largest absolute increase in employment,
about 116,000 jobs, with the other six counties in
the Region experiencing increases ranging from
27,000 jobs in Walworth County to 95,000 jobs in
Milwaukee County. Under the high-growth
