In the US, roughly 1500 PhDs are granted in Physics every year. The goal of this thread is to ascertain, by your best estimates, how many of those 1500 will be able to achieve some sort of advancement in the field. Of the 1500, how many will be accepted to a postdoctoral position (Whether it be at a university, national lab, or private lab)? Of those who are granted a postdoc, how many will be able to secure a research position (once again, whether it be at a university, national lab, or private lab)? Of those granted a research position, how many will be granted tenure and a permanent position? Thank you in advance for your input.
