Population Forecast
It is unlikely that the county will be able to continue the rate
of growth in population of the last two decades—an average
of 8.6% per decade. Growth in recent years following 2010
has slowed from the Great Recession and in the current
decade, 2010-2020, the county’s population is expected to
grow by approximately 3%, or 23,690 people, which is only
half of what was gained in the previous decade.
Over the longer term, it is anticipated that the growth rate
will prove itself to be cyclic and gain at a higher rate
between 2020 and 2030. While undeveloped land will still
be limited, the redevelopment of underused sites and other
infill projects will offer growth opportunities. This trend has
already been in effect. Since 2004, the planning commission
has tracked the location of new residential development each
year according to its Growth and Preservation Plan
categories. In 2004, 32% of new residential units were built
in existing developed areas. By 2011, the rate had gone up
to 50% of all newly constructed units.
The 2040 long range forecast for the county was formulated
by the Delaware Valley Regional Planning Commission with
input and modifications contributed by county staff. The
forecast calls for the population of Montgomery County to
reach 894,486 by 2040, an increase of 94,612 persons or
11.8% overall.
