The figures collectively constitute the largest and fastest string of job losses in records dating to 1948. They paint a picture of a job market that is quickly unraveling as businesses have shut down across the country because of the coronavirus outbreak. More than 20 million American may lose jobs this month.

The viral outbreak is believed to have erased nearly one-third of the economy’s output in the current quarter. Forty-eight states have closed non-essential businesses. Restaurants, hotels, department stores and small businesses have laid off millions as they struggle to pay bills at a time when their revenue has vanished.

All told, in the past three weeks, 16.6 million Americans have filed for unemployment aid. The surge of jobless claims has overwhelmed state unemployment offices around the country. And still more job cuts are expected. The unemployment rate could hit 15% when the April employment report is released in early May.
