Private companies in the United States shed around 20.2 million jobs in April as the COVID-19 fallout continues to ripple through the country, US payroll data company Automatic Data Processing (ADP) reported on Wednesday.

Payrolls in service-providing industries declined by 16,007,000 and goods producers cut 4,229,000 jobs, according to the report.

Large firms shed 8,963,000 workers, medium companies 5,269,000 and small businesses 6,005,000 employees, the report showed.

"Job losses of this scale are unprecedented. The total number of job losses for the month of April alone was more than double the total jobs lost during the Great Recession," Ahu Yildirmaz, co-head of the ADP Research Institute, said in a statement.

"Additionally, it is important to note that the 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," he said, noting the report does not reflect the full impact of COVID-19 on overall employment.

Economists at the Federal Reserve Bank of Chicago said Tuesday that the true unemployment rate could rise to between 25.1 percent and 34.6 percent in April, citing a new measure of labor market underutilization that is tailored to the COVID-19 crisis.

Federal Reserve Vice Chairman Richard Clarida also said on Tuesday that the unemployment rate could surge to the worst level since the 1940s as the economy is on track for a sharp contraction in the second quarter caused by the pandemic.

"We're living through the most severe contraction in activity and surge in unemployment that we've seen in our lifetimes," Clarida said in an interview with US television network CNBC.
