“It is important to note that the ADP National Employment Report is based on the total number of payroll records for employees who were active on a company’s payroll through the 12th of the month. This is the same time period the Bureau of Labor and Statistics uses for their survey,” said Ahu Yildirmaz, co-head of the ADP Research Institute. “As such, the March NER does not fully reflect the most recent impact of COVID-19 on the employment situation, including unemployment claims reported on March 26, 2020.”

This was above the consensus forecast for 154,000 private sector jobs lost in the ADP report (the job losses will be in the April report due to timing).The BLS report will be released Friday, and the consensus is for 100,000 non-farm payroll jobs lost in March.
