The natural expectation is that ATMs would make human bank tellers obsolete, or at least strongly reduce demand for bank teller jobs. And indeed the number of bank tellers per branch declined significantly: from 21 tellers per branch to about 13 per branch once ATMs had hit saturation. But this decline in teller intensity corresponded with an increase in aggregate teller employment. The number of ATMs per capita grew dramatically after 1975; but the number of bank tellers increased along with it. Bank tellers did become a smaller share of total employment, since the increase in bank teller employment was smaller than the increase in other occupations; but at no point in the period between 1970 and 2010 did the number of bank tellers actually enter a prolonged decline.
