The mantle has now been passed to the HTTP Archive, whose Web Almanac includes a section on the popularity of HTML elements:

HTTP Archive has similar data, but from the web crawler, so page views don't matter.

But it shouldn't be to hard finding each of these individually.
Here are some links I could find:
