I don't believe this answers your question directly, however late last 
year I performed some analysis[0] that showed that 64.17% of the Alexa 
Top 1 million domains I had queried for www records returned CNAME 
records that pointed to apex A records. If it is of use for this work I 
could re-run this and give you up-to-date information that answers this 
fully.
