A strong end to the season on the 2021 NWSL attendance front, with good crowds for Portland Thorns, NJ/NY Gotham and Kansas City matches.
These 2021 NWSL attendance numbers are not complete. We have based this ranking on numbers officially posted to the NWSL website. Several teams have not released attendance for all their games or began the season playing before a limited capacity, so there is a natural dip from the 2019 numbers. The total attendance for NWSL this season is likely higher than our total, but the average is likely lower.
