Foster Weeks publishes a weekly mortgage report which is updated every Monday morning. How is this affecting the San Francisco real estate market? Read our weekly and monthly market reports. Here’s what Mr. Weeks says about last week’s activity:

“BOTH OPTIMISTS AND PESSIMISTS CONTRIBUTE TO OUR SOCIETY. THE OPTIMIST INVENTS THE AIRPLANE, AND THE PESSIMIST – THE PARACHUTE.” G.B. Stern. And last week’s Jobs Report had something for both optimists and pessimists, as the numbers were both good and bad…depending on which survey you looked at, and what numbers you focused on.

First, the headline numbers: The Labor Department reported that there were 20,000 jobs lost in January, which was worse than expectations of 15,000 jobs gained. However, the Unemployment Rate came in lower at 9.7%, down from last month’s read of 10.0%. But what do these numbers actually tell us?

Remember that the numbers in the Jobs Report come from two separate surveys: First, the Business Survey – also called the Establishment Survey or Current Employment Statistics Survey – which surveys about 140,000 businesses and government agencies. It uses something called the “birth/death ratio” to provide an estimate of the number of jobs gained or lost each month. This survey is used to report the headline number of jobs gained or lost. Now there is also the Household Survey, also known as the Current Population Survey, which uses actual phone calls to 50 – 60,000 households to gather its data. This survey is used to report the headline Unemployment Rate.

The Business Survey is very susceptible to inaccuracy, particularly during times when the labor market is substantially worsening or improving…and you don’t need to look much further than all the revisions to prior reports to see how inaccurate the report seems to be. December’s report was revised to 150,000 jobs lost, nearly doubling the original report of 85,000 job losses. Although November showed 60,000 additional gains – wait a minute – October’s revisions showed another 100,000 jobs lost. And if that weren’t enough, the Business Survey threw in a “Benchmark Revision”, which indicated that there were an additional 900,000 jobs lost from March 2008 – March 2009 from what was previously reported!
