This is data as reported from the sources below, with minimal re-coding. The total claims across industries will not necessarily match what the US DOL reports as the total claims for a given state.
This data takes the above and removes unclassified sectors and then scales totals across industries to match the totals that states report weekly to the US DOL. The scaling preserves the classified industry distribution of claims within a state-week.
For example: if, after removing the unclassified sectors, the food services sector in a state-week equals 10% of the remaining total claims for that state-week, then the total claims for food services will be equal to 10% of the state-week claims that the state reports to the DOL.

For most states the data are from state employment offices.
Michigan’s data is from the W.E. Upjohn Institute, which collected data from that state’s employment office.
California’s data is from reports of the California Policy Lab, which analyzed UI claims data.
