NEW RESIDENTIAL CONSTRUCTION IN SEPTEMBER 2008
The U.S. Census Bureau and the Department of Housing and Urban Development jointly announced the following new residential construction statistics for September 2008:

BUILDING PERMITS
Privately-owned housing units authorized by building permits in September were at a seasonally adjusted annual rate of 786,000. This is 8.3 percent (±1.6%) below the revised August rate of 857,000 and is 38.4 percent (±1.6%) below the revised September 2007 estimate of 1,277,000. Single-family authorizations in September were at a rate of 532,000; this is 3.8 percent (±1.6%) below the August figure of 553,000. Authorizations of units in buildings with five units or more were at a rate of 225,000 in September.

HOUSING STARTS
Privately-owned housing starts in September were at a seasonally adjusted annual rate of 817,000. This is 6.3 percent (±12.0%)* below the revised August estimate of 872,000 and is 31.1 percent (±8.3%) below the revised September 2007 rate of 1,185,000. Single-family housing starts in September were at a rate of 544,000; this is 12.0 percent (±8.3%) below the August figure of 618,000. The September rate for units in buildings with five units or more was 254,000.

HOUSING COMPLETIONS
Privately-owned housing completions in September were at a seasonally adjusted annual rate of 1,097,000. This is 11.7 percent (±14.0%)* above the revised August estimate of 982,000, but is 20.4 percent (±9.6%) below the revised September 2007 rate of 1,378,000. Single-family housing completions in September were at a rate of 806,000; this is 17.0 percent (±11.5%) above the August figure of 689,000. The September rate for units in buildings with five units or more was 260,000. New Residential Construction data for October 2008 will be released on Wednesday, November 19, 2008, at 8:30 A.M. EST. Our Internet site is: http://www.census.gov/newresconst http://www.census.gov/newresconst EXPLANATORY NOTES
In interpreting changes in the statistics in this release, note that month-to-month changes in seasonally adjusted statistics often show movements which may be irregular. It may take 3 months to establish an underlying trend for building permit authorizations, 4 months for total starts, and 5 months for total completions. The statistics in this release are estimated from sample surveys and are subject to sampling variability as well as nonsampling error including bias and variance from response, nonreporting, and undercoverage. Estimated relative standard errors of the most recent data are shown in the tables. Whenever a statement such as “2.5 percent (±3.2%) above” appears in the text, this indicates the range (-0.7 to +5.7 percent) in which the actual percent change is likely to have occurred. All ranges given for percent changes are 90-percent confidence intervals and account only for sampling variability. If a range does not contain zero, the change is statistically significant. If it does contain zero, the change is not statistically significant; that is, it is uncertain whether there was an increase or decrease. The same policies apply to the confidence intervals for percent changes shown in the tables. On average, the preliminary seasonally adjusted estimates of total building permits, housing starts and housing completions are revised about one percent. Explanations of confidence intervals and sampling variability can be found on our web site listed above.

* 90% confidence interval includes zero. The Census Bureau does not have sufficient statistical evidence to conclude that the actual change is different from zero.
