CENSUS BUREAU REPORTS ON RESIDENTIAL VACANCIES AND HOMEOWNERSHIP
National vacancy rates in the fourth quarter 2007 were 9.6 (+ 0.4) percent for rental housing and
2.8 (+ 0.1) percent for homeowner housing, the Department of Commerce’s Census Bureau announced today. The Census Bureau said the rental vacancy rate was not statistically different from the fourth quarter rate last year, or the rate last quarter (9.8 percent each). For homeowner vacancies, the current rate was not statistically different from the fourth quarter 2006 rate or the rate last quarter (2.7 percent each). The homeownership rate at 67.8 (+ 0.5) percent for the current quarter was lower than the fourth quarter 2006 rate (68.9 percent) and also lower than the rate last quarter (68.2 percent).

NOTE: The estimates in this report are based on responses from a sample of the population and may differ from actual values because of
sampling variability or other factors. As a result, apparent differences between the estimates for two or more groups may not be statistically significant. All comparative statements have undergone statistical testing, and when significant, they are significant at the 90-percent confidence level unless otherwise noted. The data in this report are from the monthly samples of the Housing Vacancy Survey, which is a supplement
to the Current Population Survey. The populations represented (the population universe) are all housing units (vacancy rates) and the civilian noninstitutional population of the United States (homeownership rate). For an explanation of how the rates are calculated, please see pages
10-11.
For rental housing by area, the fourth quarter 2007 vacancy rates inside principal cities (9.6 percent), in the
suburbs (9.7 percent), and outside Metropolitan Statistical Areas (MSA’s), 9.5 percent, were not statistically different
from each other. When compared to a year ago, the rental vacancy rates by area were also not statistically different
from their corresponding rates.
The homeowner vacancy rate in principal cities (3.7 percent) was higher than in the suburbs (2.4 percent) and outside MSA’s (2.6 percent), although the rates in the suburbs and outside MSA’s were not statistically different from each other. When compared to a year ago, the homeowner vacancy rates by area were not statistically different from their corresponding rates.
Among regions, the rental vacancy rates for the current quarter were highest in the South (12.3 percent) and the Midwest (11.1 percent), although the 12.3 percent and 11.1 percent were not statistically different from each other. The
rates were lowest in the Northeast (6.6 percent) and the West (6.8 percent), although the 6.6 percent and 6.8 percent were
not statistically different from each other. The rental vacancy rates by region were not statistically different from their respective rates a year ago.
Regional homeowner vacancy rates for fourth quarter 2007 were lowest in the Northeast (2.2 percent). The rate in the Midwest (3.2 percent) was higher than the rate in the West (2.7 percent), but not different than the rate in the South (2.9 percent). Homeowner vacancy rates in the South and the West were not statistically different from each other. The homeowner vacancy rates by region were not statistically different from their respective rates a year ago.

aA 90-percent confidence interval is a measure of an estimate’s reliability. The larger the confidence interval is, in relation to the size of the estimate, the less reliable the estimate. For more information, see page 10.
NOTE: Metropolitan Statistical Area data for 2005 and later are not comparable to earlier data. Beginning in first quarter 2005, the Current Population Survey/Housing Vacancy Survey is using the new metropolitan and micropolitan statistical definitions that were announced by the Office of Management and Budget (OMB) in June 2003, and were based on the application of the 2000 standards to Census 2000 data. The OMB announced updates as of December 2003, based on application of the 2000 standards to more recent Census Bureau estimates. In this report, outside Metropolitan Statistical Areas includes micropolitan and non-metropolitan statistical areas. The December 2003 definitions are available at: http://www.census.gov/population/www/estimates/metrodef.html and
http://www.census.gov/population/www/estimates/aboutmetro.html.
There were an estimated 128.6 million housing units in the United States in the fourth quarter 2007. Approximately 110.9 million housing units were occupied: 75.2 million by owners and 35.7 million by
renters. The number of owner-occupied housing units was lower than a year ago, while the number of renter-occupied units was higher than the fourth quarter 2006 estimate. Of the 2.0 million increase in total housing units, 0.9 million was for occupied units and 1.1 million was for vacant units. Of the 1.1 million additional vacant units from last year, only 13 percent were for rent or for sale. The number of total vacant housing units, 17.8 million, was higher than the estimated number in fourth quarter 2006. Of these vacant housing units, 13.3 million were for year-round use and 4.4 million were seasonal. Approximately 3.8 million of the year-round vacant units were for rent, 2.2 million were for sale only, and the remaining 7.3 million units were vacant for a variety of other reasons.

aA 90-percent confidence interval is a measure of an estimate’s reliability. The larger the confidence interval is, in relation to the
size of the estimate, the less reliable the estimate. For more information, see page 10.
(X) Not Applicable. Since the number of housing units is set equal to an independent national measure, there is no sampling
error, and hence no confidence interval.
NOTE: Since first quarter 2003, the Current Population Survey/Housing Vacancy Survey (CPS/HVS) estimates have been controlled to
independent housing unit counts. Doing so should make the CPS/HVS estimates of housing units more comparable to other
Census Bureau housing surveys. Please see page 10 for additional information.
The homeownership rate (67.8 percent) for the current quarter was lower than the fourth quarter
2006 rate (68.9 percent), and also lower than the rate last quarter (68.2 percent).

The homeownership rates by age of householder for fourth quarter 2007 were highest for those age 55 to
64 (80.4 percent), and those age 65 years and over (80.3 percent), although they were not different from each other. Second highest were those in the age category 45 to 54 years (75.1 percent). Homeowners age 35 to 44 years (67.2 percent) were third, while the lowest rate was for the under 35 years of age (41.0 percent) group. The rates for the under 35 age group, the 35 to 44 age group, the 45 to 54 age group, and the 65 and over age group were lower than their respective rates a year ago, while the rate for the 55 to 64 age group was not statistically different from the rate in fourth quarter 2006.

aStandard errors for quarterly homeownership rates by race and ethnicity of householder generally are 0.3 percent for non-Hispanic White
(single race) householders, 0.6 percent for Black (single race) householders, 0.8 percent for All Other Races householders, and 0.6 percent for
Hispanic householders.
bThe homeownership rate for fourth quarter 2007 for householders who reported Black whether or not they reported any other race was 47.7 percent.
c Includes people who reported Asian, Native Hawaiian or Other Pacific Islander, or American Indian or Alaska Native regardless of whether
they reported any other race, as well as all other combinations of two or more races.
NOTE: Beginning in 2003, the question on race on the CPS was modified to comply with the revised standards for federal statistical agencies.
Respondents may now report more than one race, but small sample sizes preclude showing all race categories. The question on Hispanic
origin is asked separately, and is asked before the question on race. For further information on each major race group and the Two
or More Races populations, see reports from the Census 2000 Brief series (C2KBR/01), available on the Census 2000 Web site at
http://www.census.gov/population/www/cen2000/briefs.html.
In fourth quarter 2007 the homeownership rate for households with family incomes greater than or
equal to the median family income (83.0 percent) and the rate for those with family incomes less than the
median family income (50.9 percent) were lower than their corresponding rates a year ago.

aStandard errors for quarterly homeownership rates by family income generally are 0.3 percent.
bBased on families or primary individuals reporting income.
cRevised in 2002 to incorporate information collected in Census 2000.
Note: This press release, along with more detailed data, is available on the Internet. Our Internet address is: |
The estimates in this release are based on a sample survey and therefore are subject to both sampling
and non-sampling error. Sampling error is a result of not surveying the entire population. Non-sampling error occurs because accurate information cannot always be obtained.
The sample estimate and its standard error enable one to construct a confidence interval. A confidence
interval is a measure of an estimate’s reliability. The larger a confidence interval is in relation to the size of
the estimate, the less reliable the estimate. For example, the standard error on the estimated rental vacancy
rate of 9.6 percent is 0.255 percentage points. Then the 90-percent confidence interval is calculated as
9.6 + (1.645 x 0.255) percent, or 9.6 + 0.4195 percent, or from 9.2 percent to 10.0 percent. If all possible
samples were surveyed under essentially the same general conditions and the same sample design, and an
estimate calculated from each sample, then 90 percent of the estimates would fall within the 90 percent
confidence interval, in this case, from 9.2 percent to 10.0 percent.
Beginning with first quarter 2003, population controls that reflect the results of Census 2000 are
used in the CPS/HVS estimation process. As a final additional step in the process, the estimates are
controlled to independent housing counts used for the first time in order to produce a more accurate estimate of
housing units. This new procedure should make the CPS/HVS estimates of housing units more consistent with
other Census Bureau housing surveys. The new housing controls affect the estimate of vacant units in the
sense that the estimates of total occupied and vacant units sum to the new control total. Vacancy rates and
homeownership rates are not affected by this change.
The CPS/HVS also began computing first-stage factors (used for weighting purposes) based on
year-round and seasonal counts of housing units from Census 2000 for the first quarter 2003. From 1980 to
2002, the CPS/HVS first-stage factors were based on year-round estimates only. The effect on the data is
slight and the change should improve the counts of year-round and seasonal units. For more information on the
effects of these changes, please see Source and Accuracy Statement at www.census.gov/hhes/www/hvs.html.
The question on race on the CPS was modified beginning in the first quarter 2003 to comply with
new standards for federal statistical agencies. Respondents are now asked to report one or more
races. The question on Hispanic origin is asked separately, and is asked before the question on race.
First stage factors for year-round vacant units have been corrected as of the second quarter 2004.
Research has shown that this correction had no significant effect on the vacancy rates or homeownership rates.
The rental vacancy rate is the proportion of the rental inventory that is vacant for rent. In tables 1 and 2
the rates are computed using the following formula.
The homeowner vacancy rate is the proportion of the homeowner inventory that is vacant for sale. In
tables 1 and 2 the rates are computed using the following formula.
The homeownership rate is the proportion of households that is owner-occupied. It is computed by
dividing the number of households that are occupied by owners by the total number of occupied households
(tables 4, 4SA, and 5).
For the homeownership rate for a specific characteristic (tables 6-8), use the owner and total number
of units for that characteristic. For example, for the West region,
