Massive job revisions by the Bureau of Labor Statistics leave experts puzzled, as nearly 90% of gains for May and June were wiped out. Delving into the data collection methods reveals significant challenges, especially with a 560,000 business survey that often lacks timely responses. Inconsistencies arise when comparing BLS data with ADP's payroll insights.

Episode notes
How BLS Jobs Data Is Compiled
- The BLS jobs report relies on payroll data from 560,000 work sites, with only 60-73% responding by the initial release date.
- The rest are estimated by statistical models based on historical patterns, which can cause large errors during rapid economic shifts.
Why Job Report Revisions Are Massive
- The BLS' use of past data models fails when economic conditions change rapidly, causing major job report revisions.
- This is similar to 2009, when the Great Recession also challenged predictive accuracy and caused major revisions.
ADP Data Validates BLS Revisions
- Private payroll processor ADP's monthly job reports provide an independent data source covering 460,000 companies.
- Comparing ADP data to BLS revisions boosts confidence in revised job numbers and reveals the magnitude of initial errors.
