If you lot larn to the recent liberate from the BLS, you lot tin detect these 2 sentences a few paragraphs apart:
Total job rose yesteryear 873,000 inwards September.
Total nonfarm payroll job increased yesteryear 114,000 inwards September.
To a layman, this may appear confusing. The get-go contention suggests a robust project market, the bit a to a greater extent than lackluster one. What is going on?
The lawsuit is that at that topographic point are 2 surveys. The get-go gauge of employment comes from the survey of households; the bit is from the survey of establishments. I idea readers powerfulness similar to ask heed what my favorite intermediate macro textbook says almost this issue. Here is an excerpt:
-----
More of import than the specifics of these surveys or this item episode when they diverged is the broader lesson: all economical statistics are imperfect. Although they comprise valuable information almost what is happening inwards the economy, each i should hold upwardly interpreted with a salubrious dose of caution as well as a chip of skepticism.

Because the BLS conducts 2 surveys of labor-market conditions, it produces 2 measures of full employment. From the household survey, it obtains an gauge of the number of people who order they are working. From the institution survey, it obtains an gauge of the number of workers firms possess got on their payrolls.
One powerfulness human face these 2 measures of job to hold upwardly identical, only that is non the case. Although they are positively correlated, the 2 measures tin diverge, especially over brusk periods of time. Influenza A virus subtype H5N1 specially large departure occurred inwards the early on 2000s, every bit the economic scheme recovered from the recession of 2001. From Nov 2001 to August 2003, the institution survey showed a refuse inwards job of 1.0 million, land the household survey showed an increment of 1.4 million. Some commentators said the economic scheme was experiencing a “jobless recovery,” only this description applied exclusively to the institution data, non to the household data.
Why powerfulness these 2 measures of job diverge? Part of the explanation is that the surveys mensurate dissimilar things. For example, a somebody who runs his or her ain occupation concern is self-employed. The household survey counts that somebody every bit working, whereas the institution survey does non because that somebody does non exhibit upwardly on whatever firm’s payroll. As to a greater extent than or less other example, a somebody who holds 2 jobs is counted every bit i employed somebody inwards the household survey only is counted twice inwards the institution survey because that somebody would exhibit upwardly on the payroll of 2 firms.
Another purpose of the explanation for the departure is that surveys are imperfect. For example, when novel firms start up, it may accept to a greater extent than or less fourth dimension earlier those firms are included inwards the institution survey. The BLS tries to gauge job at start-ups, only the model it uses to create these estimates is i possible origin of error. Influenza A virus subtype H5N1 dissimilar job arises from how the household survey extrapolates job with the surveyed households to the entire population. If the BLS uses wrong estimates of the size of the population, these errors volition hold upwardly reflected inwards its estimates of household employment. One possible origin of wrong population estimates is changes inwards the charge per unit of measurement of immigration, both legal as well as illegal.
In the end, the departure betwixt the household as well as institution surveys from 2001 to 2003 remains a mystery. Some economists believe that the institution survey is the to a greater extent than accurate i because it has a larger sample. Yet i recent report suggests that the best mensurate of job is an average of the 2 surveys.
