BLS = Bureau of Labor Statistics 

There are three kinds of lies: lies, damned lies, and statistics. – Benjamin Disraeli via Mark Twain

The BLS gets that data [employment data] by contacting a representative sample of the population and then weights those results to reflect the broader population. The trouble is…that sample is at risk of getting smaller. And one key reason for that… is how much money the BLS has to conduct those surveys. – Bloomberg
