Neurotree growth.
This chart shows the number of people added to Neurotree each quarter since it was created in January 2005. The more general academictree.org effort to build similar genealogies for other fields provides the exciting opportunity to develop a single graph of mentorship networks across all of academia. Is your field missing? Let us know, and we can create a tree for your field!

Note, this graph excludes data imported from the ProQuest dissertation database, which produced a large spike of data starting June 2015. Instead, all the data pictured here was added by users like you. Thanks!

Node vs. connection growth
It's also interesting to compare the rate of growth of nodes vs. connections. So far, they've grown at a similar pace, but as the tree is getting larger, the number of new connections seems to be gradually outpacing the number of new nodes.
