NEW RESIDENTIAL CONSTRUCTION IN JANUARY 2011
The U.S. Census Bureau and the Department of Housing and Urban Development jointly announced the following new residential
construction statistics for January 2011:

10.4 percent (±1.8%) below the revised December rate of 627,000 and is 10.7 percent (±1.2%) below the January 2010 estimate of
629,000.
Single-family authorizations in January were at a rate of 421,000; this is 4.8 percent (±2.3%) below the revised December figure of
442,000. Authorizations of units in buildings with five units or more were at a rate of 125,000 in January.
HOUSING STARTS

15.7%) the revised December estimate of 520,000, but is 2.6 percent (±9.8%)* below the January 2010 rate of 612,000.
Single-family housing starts in January were at a rate of 413,000; this is 1.0 percent (±8.6%)* below the revised December figure of
417,000. The January rate for units in buildings with five units or more was 171,000.
HOUSING COMPLETIONS
Privately-owned housing completions in January were at a seasonally adjusted annual rate of 512,000. This is 9.5 percent (±6.3%)
below the revised December estimate of 566,000 and is 22.7 percent (±8.3%) below the January 2010 rate of 662,000.
Single-family housing completions in January were at a rate of 428,000; this is 7.0 percent (±7.0%)* below the revised December rate

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, 3 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 two percent or less. 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.
