Where Are The Headcount Numbers?

     I'm used to posting data on a quarterly basis from the Office of Personnel Management (OPM) on the number of employees at Social Security. I think the headcount is an important number that helps explain the level of service the agency provides. I haven't posted this number in about a year because OPM hasn't released any new numbers in about a year. I know that the Trump administration is threatening major change at OPM, which I don't understand, but why would they shut down this function? Is Social Security's headcount available through any other public source?
