In any academic department, faculty members retire or leave for a variety of reasons, and new faculty members are hired to replace departing faculty or fill newly created positions. This report focuses on departures, retirements, recruitments, and new hires in physics and astronomy departments. In our Academic Workforce Surveys, we collect the number of faculty departures in the previous academic year, the number of retirements for the "previous" and the "current" academic year, the number of new hires in the "current" academic year, and the number of recruitments for the "following" academic year. These are the most current data the departments can report. Thus, the numbers for departures, retirements, recruitments, and new hires reflect different academic years.
