Daily Deranged

From cpa1's diary:
With regards to unemployment being an economic indicator, you have to realize from where it is coming. I don’t think for a second that our unemployment rate is 4.5%. I’d believe those figures as much as I believed there were weapons of mass destruction, we will be greeted in the streets of Baghdad with flowers and Dick Cheney has integrity and a conscience. With Bush, Cheney and Rove, there is nothing you can believe.
My italics. Let me be of assistance. Here's how unemployment is actually calculated (from the :
...[T]he Government conducts a monthly sample survey called the Current Population Survey (CPS) to measure the extent of unemployment in the country. The CPS has been conducted in the United States every month since 1940 when it began as a Work Projects Administration project. It has been expanded and modified several times since then. As explained later, the CPS estimates, beginning in 1994, reflect the results of a major redesign of the survey.

There are about 60,000 households in the sample for this survey. The sample is selected so as to be representative of the entire population of the United States. In order to select the sample, first, the 3,141 counties and county-equivalent cities in the country are grouped into 1,973 geographic areas. The Bureau of the Census then designs and selects a sample consisting of 754 of these geographic areas to represent each State and the District of Columbia. The sample is a State-based design and reflects urban and rural areas, different types of industrial and farming areas, and the major geographic divisions of each State.

Each of the 754 areas in the sample is subdivided into enumeration districts of about 300 households. The enumeration districts, in turn, are divided into smaller clusters of about four dwelling units each, through the use of address lists, detailed maps, and other sources. Then, the clusters to be surveyed are chosen statistically, and the households in these clusters are interviewed.

Every month, one-fourth of the households in the sample are changed, so that no household is interviewed more than 4 consecutive months. This practice avoids placing too heavy a burden on the households selected for the sample. After a household is interviewed for 4 consecutive months, it leaves the sample for 8 months and then is again interviewed for the same 4 calendar months a year later, before leaving the sample for good. This procedure results in approximately 75 percent of the sample remaining the same from month to month and 50 percent from year to year.

Each month, 1,500 highly trained and experienced Census Bureau employees interview persons in the 60,000 sample households for information on the labor force activities (jobholding and jobseeking) or non-labor force status of the members of these households during the week that includes the 12th of the month (the reference week). This information, relating to all household members 16 years of age and over, is entered by the interviewers into laptop computers; at the end of each day's interviewing, the data collected are transmitted to the Census Bureau's central computer in Washington, D.C. In addition, a portion of the sample is interviewed by phone through two central data collection facilities. (Prior to 1994, the interviews were conducted using a paper questionnaire which had to be mailed in by the interviewers each month.)

I wonder where in this process cpa1 thinks Bush, Cheney, and Rove cooked the books (and got away with it). Maybe he will clarify this for me.
