^[1] As discussed in the main text, our revised classification or DFLP modifies that originally developed by Jonathan I. Dingel and Brent Neiman (“How many jobs can be done at home?” Journal of Public Economics, vol. 189, no. 2, September 2020). ^[2] In the Dingel and Neiman method, an occupation begins in the “suitable for telework” category. If any of the preceding variables listed exceed the cutoff, the occupation moves into the “not suitable for telework” category. If no cutoff is listed, the method does not use the variable. ^[3] For DFLP, the variable must exceed the cutoff value to be moved into the “not able to telework” category. ^[4] For DFLP, the variable must exceed the cutoff value to remain in the “suitable for telework” category. Similarly, electronic mail must exceed the cutoff value in the Dingel and Neiman rules to remain in the “suitable for telework” category. Note: Cutoff values represent a range, with 1 as “Not important at all” and 5 as “Very important.” A dash indicates that the variable is not used in ascertaining whether an occupation is suitable for telework. DFLP = Dey, Frazis, Loewenstein, and Piccone; O*NET = Occupational Information Network. Source: U.S Bureau of Labor Statistics.
