WaPo Feb 26, 2021 8:40 PM ET Data on a subset of businesses ― those registered as corporations ― show that some sectors are faring much worse than others, with restaurants, retailers, entertainment companies, real estate firms and oil and gas ventures filing for protection in far greater numbers than in previous years, according to New Generation Research. Bankruptcies filed by entertainment companies in 2020 nearly quadrupled, and filings nearly tripled for oil and gas companies, doubled for computer and software companies and were up 50 percent or more for restaurant owners, real estate companies and retailers, compared with 2019, data from the research firm show. There were 5,236 Chapter 11 filings in 2019, but 6,917 last year, a tally at least 30 percent higher than any of the previous four years.
