There is no single public, exact number for how many total crew members worked on the Eras Tour, and the figure varied by city and leg of the tour.
What is known
Reports about Taylor Swift’s tour operation describe a very large traveling workforce that includes performers (band, dancers, backing vocalists) plus technical, production, logistics, security, catering, and trucking staff. For example, coverage of her end-of-tour bonuses notes that the nearly 200 million dollars in bonuses were distributed across everyone working on the tour, which implies a crew in the low thousands when spread over all roles and locations, though no outlet gives an exact headcount.
Performers vs full crew
Public sources do break out the onstage performing group: 6 core band members, 4 backing vocalists, and about 15 dancers for the main concert ensemble. However, those numbers only cover the visible performers and not the much larger offstage crew of drivers, riggers, sound and lighting techs, and other specialists that make up the full Eras Tour operation.
