evidence: The federal government responded to the challenges of the COVID-19 pandemic by transforming the UI program. [...] Administrative UI data from the Department of Labor show the magnitude of disruption and changes to the UI program triggered by the pandemic. In the second quarter of 2019, before the pandemic hit the United States, 2.6 million UI claims were filed. In the second quarter of 2020, 33.7 million claims were filed. [...] The living situation of UI recipients has also changed during the pandemic. The SIPP data from 2018 show that 15.6% of UI recipients lived alone. By June 2021, the HPS shows that only 7.0% of households that reported receiving UI that year were single-person households.
