“Net of the Concurrent Seasonal Factor Bias and net of distortions built into the reporting by the Birth-Death Model, the June jobs loss likely exceeded 700,000.
“John Williams (Shadow Government Statistics) on the goofy B/D Model: ‘The system was not designed to accommodate recessions, but the benchmark revisions tended to show a pattern of fairly consistent overstatement with the annual revisions, regardless of the business cycle. During the reporting cycle covering the 1990 to 1991 recession, a particularly large downward benchmark revision in previously reported payrolls levels was blamed partially on the BLS assuming that companies that had stopped reporting during the recession still were in business, with proportionate payroll employment attributed to them by the BLS. The problem was that much of the non-reporting reflected companies going out of business. The bulk of that modeling was based on periods of economic growth.
“‘The unadjusted annual decline in June payrolls was the deepest since a similar decline at the trough of the 1958 recession, but still shy of the 4.9% trough seen in the 1949 downturn. When the 1949 annual low growth is broken, possibly next month, the annual percentage contraction in payrolls will be the most severe since the production shutdown following World War II.’”
