Here's the process:
On January 15th, collection for the Employment Situation started. Census sent out interviewers to over 15,000 households across the country and made telephone calls to about 45,000 more (who all had previously been interviewed in person). This was for the Current Population Survey (Labor Force Data) and it took all week with all questions being about the week of Jan 8-14.
At the same time, BLS employees recieved reports or initiated interviews with around 486,000 individual worksites asking about the pay period that included Jan 8-14. This was the Current Employment Statistics Survey (non-farm payroll...jobs gained/lost).
Initial processing, collation, follow-ups etc happened during the week of Jan 22-28.
January 30, the Office of Employment and Unemployment Statistics went into lockdown with no one outside the office could not enter the offices without escort (this includes cleaning and maintenance staff) as the final report was put together (
Employment Situation) 42 pages. On Thursday, February 2nd, the report was given to the Commissioner to sign off, and the report was sent to GPO for publishing. The Chief of the Council of Economic Advisors was given an advance copy.
At 8:00am on February 3rd, the Secretary of Labor was given a copy and the press were put into a tiny room and their computers, tablets, and phones were confiscated. Then they were given the release and could write their notes with pen and paper.
At exactly 8:30 am by the Naval Observatory, the report was issued.
So riddle me this Batman....At what point would it have been possible to review and make changes? Keep in mind the number of tables and the huge amount of data for both reports. You change one data cell, you can change the numbers by thousands. You want to change the number of unemployed, you have to specify age, race, veteran status, disability, duration of unemployment, reason for unemploymnent, occupation, native or immigrant and probably a whole lot of things I'm forgetting.
So how do you think it could be manipulated?
