A contributing factor in the period of increase may have been the introduction of automated teller machines due to the impact of induced demand: ATMs allow a branch to operate with fewer tellers, making it more economical for banks to open more branches, necessitating more tellers to staff those additional branches.
In the later 2010s and the 2020s, automation and online banking (as anticipated[3]) reversed this trend, leading to only 364,100 in 2022.
