Best platform to publicaly share data I'm in the final stage of my PhD, and want to make my datasets publicly available. This is so that my examiners can re-run my regressions, if they wish; but moreover, I want other scholars to be able to use the datasets I compiled for their own purposes. I spent years putting these together, and see no purpose in keeping it to myself "just because". The information is not sensitive, and is already in the public domain (e.g, government statistical sites), albeit mostly in unprocessed form.

Is there a best practice in this regard - a "GitHub" equivalent for datasets?
I'm biased, as a long-time IEEE member, but I recommend IEEE Dataport as a good place to store large data sets that are likely to be of interest to others.
As their About page says:

IEEE DataPort™ is a universally accessible web-based portal that serves four primary purposes:

Enable individuals and institutions to indefinitely store and make datasets easily accessible to a broad set of researchers, engineers and industry;
Enable researchers, engineers and industry to gain access to datasets that can be analyzed to advance technology;
Facilitate data analysis by enabling access to data in the AWS Cloud and by enabling the downloading of datasets
Supports reproducible research.
