In April 2017, these numbers were 543 and 364K. [IEDF 2017]
Not unique individuals: many are members of multiple groups.
The groups are not equally popular.
Just 36 groups contain more than a third of all members.
Three groups stand out in the domains of AI and IoT.
60% of all groups have < 500 members.
75% of all groups have < 1000 members.
Only 2-3% of groups (exactly 17 groups) have > 5000 members.
21% of all groups have < 100 members: (0.19+0.17)*59% = 21%
34 groups meet at least twice a month. Only 5 of these are big groups.
Some big numbers are misleading: group is configured to auto-schedule meetups.
Big groups who don't meet often (small circles) suggest scope for new groups on similar topics.
Incredibly, 24% of groups have not met even once.
Only 12% are meeting at least once a month.
Any correlation between the group's age or number of events and its membership strength?
ML/AI and analytics are the most popular topics.
