Securing a position as an assistant professor at a reputable university is challenging, with only about 25% of institutions offering tenure-track openings in a given year, translating to approximately 15 jobs annually at top 60 universities. The difficulty of obtaining these positions varies by field; for example, candidates with Ph.D.s in finance or math education may find it easier compared to those in physics, where job prospects have been declining since the 1970s due to structural issues. Resources like the American Institute of Physics (AIP) provide relevant statistics that highlight these trends in academia.
