the closest thing is the fellow survey.
Fellows Perspectives on Procedures and the Nephrology Job Market

Of course, this does not survey graduates. Therefore these fellows are still in the honeymoon phase and giving gushing reviews. Let's see how the marriage goes.
Gosh... that's a pitifully low salary.
While "money isn't everything," you would be hard pressed to live on this salary (after taxes) unless you are outside of a large metro area and you do not plan on becoming a homeowner and having children.
Hook.. line.. and sinker.
I work 60-70 hours a week but I pull in an obscenely higher quantity than that. I won't mention the specifics since no one will believe me anyway. But the key is to have your own in office procedures and minimize travel time so you can maximize revenue. Hence, if you love nephrology then do academics. Stay away from the career death trap of private practice nephrology.
If you plan to do private practice in any capacity, stay away from nephrology.
I would counter that every IM subspecialty and GIM has longitudinal care. This "benefit" is only valid when comparing to a surgical subspecialty in which a surgical issue is addressed and that might be the end of it. However, if you mean seeing the patient at least 4 times a month for on HD rounds, then you yes nephrology wins by a landslide lol... an poorly compensated landslide lol
