ISC runs a monthly survey of DNS statistics: https://ftp.isc.org/www/survey/reports/current/fpdns.txt (this is from January 2017). Information about the survey is here: https://ftp.isc.org/www/survey/reports/current/survey.html Not sure how useful their data is, but they have been doing it for a long time, so they have great trending analysis.
Do note, however, that fingerprinting DNS servers has gotten much harder over time, so take the results with a very large grain of salt. For example, the software that runs that survey seems to think that there are no versions of BIND 9 since 9.4.0a0.
