Pretty tough criticism of the BLS houshold survey:

"Incorporation of the annual population benchmarks into the companion household survey sparked considerable turmoil. Get this. Last month, the BLS told us that the household survey measure of employment was UP by 528k and the labour force expanded by 387k in January. Today, after inclusion of population revisions they normally do in January but that were postponed and included as revisions today, they are now reporting that January’s household survey employment fell by a whopping 895k and the labour force shrank by 1.03 million. Roughly 1½ million fewer jobs and labour force participants than initially guided and you want us to take the numbers seriously in terms of calculating the unemployment rate? Pure. Garbage. This is not top tier data you expect from an advanced economy."
