Today, the Joint Center for Housing Studies posted its
latest household projections. These new projections
incorporate several updates to data that were made since our last projections
in 2010. The 2013 projections use the
Census Bureau 2012 Population Projections (released in late 2012 and early
2013), and also use more recent data to
derive headship rates (ratios of households per person), specifically using
data from the 2011-2013 Current Population Estimates and Current Population
Survey March Supplements.
Aside from the new data, the JCHS projection methodology
remains largely unchanged from that used to create the 2010 series. The most
notable change is that unlike in 2010 we do not make any adjustment to the
Census Bureau’s population projections, as our concerns about what seemed to be
overly high estimates of future immigration levels have now been addressed in
the latest projections from Census. Since we are using the 2012 Census
population projections as published, the 2013 JCHS household projections now contain
high, middle, and low series, whereas the 2010 projections only had a high and
a low series. The projections are also
carried out an additional ten years, and so now extend to 2035.
The 2013 JCHS household projections are consistent with
those from 2010. In the near term
(2015-2025), they call for annual household growth rates ranging from 1.16
million in the low series to 1.32 million in the high series, not far from the
span of 1.15–1.36 million per year in our 2010 projections. Differences between the 2013 and 2010 series largely
follow differences in the underlying population projections (Figure 1).
Some difference is also due to updated headship rates, which are calculated
for every 5-year age group by race and averaged across the years 2011, 2012,
and 2013. These are now slightly lower overall than those from 2007, 2008, and 2009
used in the 2010 projections (Figure 2). (Click to enlarge.)

Tenure Scenarios
Presented as Well
The report also includes a simple homeowner and renter projection scenario. Under a steady-state scenario of constant
homeownership rates by age, race, and household type, this analysis offers one
look at how demographic changes in the composition of households may influence future
homeownership rates. In this scenario, changing demographics are
expected to be a positive influence on the overall homeownership rate through
about 2025 (Figure 4). After that time, the upward influence of the
aging of the population gives way to greater downward pressure from young adult
and minority household growth. Figure 4
shows how downward pressure on homeownership rates is steepest in the high
projections which, unlike the middle- and low-projections, expects no demographically
driven growth in homeownership rates through 2025.

Users of these estimates are cautioned that that they should
be considered baseline projections and not a growth forecast. Actual household
growth could deviate dramatically over short
periods of time, as the projections reflect long-run, demographically driven
trends and do not allow for any adjustments either upward or downward in
response to changing economic conditions or cyclical factors. Indeed, favorable economic conditions could
increase headship rates above levels assumed in the projection and increase
household growth, while a variety of factors could weigh down economic
opportunities and result in lower household formation rates that depress future
household growth.
