Why do the jobs numbers get revised?

our markets and policymakers want data NOW but employer data dribbles in over months

1st estimate is based on the 75% of employers who respond promptly

Updates occur as more data rolls in: 95% response rate by final revision 1/N

The initial estimate of job change for a month is based on the growth or loss of jobs at the businesses that have reported their data. Generally, BLS assumes that the employment situation at businesses that had reported is representative of the situation at those that had not yet reported. BLS continues to collect outstanding reports from the
businesses in the sample as it prepares a second and then a third estimate for the month. With each subsequent estimate, more businesses have provided their information. In 2012, the average collection rate at the time of the third estimate for a month was 94.6 percent. (See chart 1.)

  1. Reminds me of how my boss wants interval level data on a daily basis and I have to constantly remind him that until the data is properly correlated, anything we read into it is subject to change.

  2. I have heard that the response rate has declined in recent years, which has created more uncertainty in the initial estimate numbers.

    That may explain why the revisions this month were bigger than they normally are.

    There may be some underlying issues here.

  3. And it would make sense that firms doing above average, for them, hiring or firing, would be late in filing their reports. Hence, big swings in turbulent times.

  4. Thanks for the intelligent perspective that could be posted on TRUTH social or Fox News ! Those with intelligent brains understand adjustments to initial ideas based on further information.

  5. Trump is so ignorant, he makes the same stupid mistake with early, not yet complete statistics that he makes with elections. I was surprised to learn that I had always attached the words evil and genius before Dubya showed me I was wrong, but Trump is the epitome of evil stupidity, a record forever.

  6. BLS could wait to report jobs growth until they hit that 95% response rate months later

    But then we wouldn't have an any estimate of June jobs until August

    Tradeoff is btw faster vs more accurate estimates

    2/ N

    So why doesn't BLS wait until it has all the reports to make the estimate and avoid revisions? Users of the data are intensely interested in the earliest possible read on labor market developments, and experience suggests that the initial estimate is generally very good. For example, in 2012, the average monthly employment change using the first estimate would have been +142,000, compared with a monthly average change of +165,000 using the third estimate. (See table 1.) Nevertheless, it is true that in some months, revisions are large enough that they change the users' perspectives on the current state of the economy. In November 2012, for example, the initial estimate of over-the-month change was +146,000, while the third estimate was +247,000.

  7. plus, in boom times, the slowest reporters are probably those who are sesperately hiring to keep up. So we revise upwards. And in recession, the ones late to report just laid off people so they have no capacity for reporting. So we revised downward.

  8. Given Trump's tariff policies and his constant TACOing, businesses are having a devil of a time with head count. One month, they may be over-hiring bc they need to import more to get ahead of the tariffs. Next month, they let everyone go.

  9. I’ve been a responder to BLS reports on behalf of my 2 small businesses for years.Sometimes I get to them right away.Other times it can take weeks especially if I happen to miss an email reminder. I tend to be on top of things so I can only imagine the thousands of small business owners that are not
