From a Post by Alice Meadows at ORCiD:
Every year in October – to coincide with the anniversary of the ORCID Registry launch – we take a snapshot of publicly shared information in the ORCID Registry – ORCID iDs for all registrants, plus name and information about employment and education affiliations, grants and awards, publications and other outputs, and more, where record-holders have chosen to make that data public.
The number of ORCID records has grown substantially in the last year – from ~1.6 million in the 2015 file to ~2.6 million in the 2016 file. Almost 40% of the records have at least one associated work, affiliation, or person identifier. And the number of associated unique DOIs has increased by 60% over 2015, to 7 million.
