Everyone should remember that due to graduations, June has far more entrants into the civilian labor force, than your typical month.
BLS doesn't kick anyone out of the civilian labor force...the categories are self reported. If someone reports that they are not working and haven't looked in more than 4 weeks they (and proportionately the number they represent in the sample) are counted as Not in the Labor Force. It's all based on the survey reponse, not some arbitrary categorizing as you seem to imply.
And as a matter of fact, the Labor Force has increased every month this year.
Where to begin?
First, the Bureau of Labor Statistics used TWO different surveys with respect to employment.
One is the “Household” and the other the “Establishment” (employer).
Second, the “Household” survey is available in both “Not seasonally adjusted,” and “Seasonally adjusted “ formats. Both are “official.” In fact, the annual data is only available in the Not seasonally adjusted format.
Third, BLS (the adjustment bureau) does make adjustments in the data other than pure seasonal adjustments. One of the most significant is their presumptions as to new businesses (and jobs) created.
Let me provide one recent example of adjustments by the BLS:
According the BLS, the Civilian noninstitutional population amounted to approximately 238,889,000 in December of 2010, but 238,707,000 in January of 2011. Now, this decrease of approximately 182,000 is NOT the result of a real decrease in the population of the United States of persons 16 years and over, but rather the result in “changes in populations controls” made by the BLS.
Now, the BLS presumed a really huge drop in the Seasonally adjusted Civilian Labor Force during the same period, with December of 2010 having approximately 153,690,000 and January of 2011 having approximately 153,186,000 (that’s a drop of approximately 504,000)!
In conclusion, be wary of BLS data.
