NEW RESIDENTIAL CONSTRUCTION IN JULY 2007
The U.S. Census Bureau and the Department of Housing and Urban Development jointly announced the following new residential construction statistics for July 2007:

BUILDING PERMITS
Privately-owned housing units authorized by building permits in July were at a seasonally adjusted annual rate of 1,373,000. This is 2.8 percent (±1.3%) below the revised June rate of 1,413,000 and is 22.6 percent (±1.3%) below the revised July 2006 estimate of 1,774,000. Single-family authorizations in July were at a rate of 1,003,000; this is 1.6 percent (±1.2%) below the June figure of 1,019,000. Authorizations of units in buildings with five units or more were at a rate of 314,000 in July.

HOUSING STARTS
Privately-owned housing starts in July were at a seasonally adjusted annual rate of 1,381,000. This is 6.1 percent (±7.0%)* below the revised June estimate of 1,470,000 and is 20.9 percent (±6.1%) below the revised July 2006 rate of 1,746,000. Single-family housing starts in July were at a rate of 1,070,000; this is 7.3 percent (±6.7%) below the June figure of 1,154,000. The July rate for units in buildings with five units or more was 275,000.

HOUSING COMPLETIONS
Privately-owned housing completions in July were at a seasonally adjusted annual rate of 1,512,000. This is 0.1 percent (±9.5%)* below the revised June estimate of 1,513,000 and is 22.2 percent (±7.6%) below the revised July 2006 rate of 1,944,000. Single-family housing completions in July were at a rate of 1,203,000; this is 4.0 percent (±9.3%)* below the June figure of 1,253,000. The July rate for units in buildings with five units or more was 280,000. New Residential Construction data for August 2007 will be released on Wedneday, September 19, 2007, at 8:30 A.M. EDT. 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 6 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.
