My colleague Adam Summers pointed out this interesting column.
How does the BLS know that there were 274,000 new jobs? Not by counting them. It has a statistical formula which includes the likely creation of new businesses and the likely demise of old businesses. This is called the birth-death ratio.
Let me assure you, the journalists who report the employment figures do not report the following. That's because hardly anyone knows about it, and of those who do, hardly anyone understands it, and of those who do understand it, hardly anyone knows what the BLS formula is or how the samples are made. The Bureau of Labor Statistics does publish a page about the birth-death ratio.
