Current status and trends in the choice of software for teaching econometrics
In 2008 the American Economic Association (AEA) created a reproducible research requirement about posting the code and the data for their papers. According to analysis done by the AEA Data Editor Vilhuber, Turrito, and Welch (2020), Stata and Matlab were by far the most dominant software used in these submissions (see figure below, the raw data are here). Given the elite status of this family of journals in the profession, I think this is a reasonable proxy for the software used by elite economists and therefore in elite economics PhD training programs. For what it is worth, Stata and Matlab (and in that order) were also the software I was trained to use in my PhD econometrics classes and my work for my economics PhD, about ten years ago, at an R1 school in the USA. The only exception was my Bayesian econometrics class which I believe used R. As an undergraduate (also at a R1 school in the USA), I used Eviews in my econometrics classes and R in my probability and statistics classes.
