We examine top LinkedIn groups in Analytics, Big Data, Data Mining, and Data Science from the Big Bang era of group creation to present, and identify the largest groups, the fastest growing groups, and 2 main clusters.
DW/BD/H: Data Warehouse / Big Data / Hadoop / Predictive Analytics, 32994 members, 19% growth
We note the remarkable growth of Adv BADM group, which overtook BI Pros for the title of the largest LinkedIn group in this area.
Here are the 10 groups with the fastest growth from Q1 2014 to Q1 2015.
Data Science & Machine Learning (DS & ML), 165% growth, created 10-Dec-11
RDataMining: R and Data Mining (RDM), 142%, created 30-Aug-11
Big Data, Analytics, Hadoop, NoSQL & Cloud Computing (BDAHN), 112%, created 6-Jul-11

Data Mining, Statistics, Big Data, and Data Visualization (DMSBD), 62%, created 25-Jul-08.
Not surprisingly, most of these fast growing groups are newer, founded in 2011/2012.
The chart below shows group growth vs month created. Color corresponds to growth rate in 2014 vs 2013 - redder is faster, bluer is slower. Group name abbreviations are in the table below.

We again note two clusters of groups - "old" groups, created in the first "burst" of activity in 2008-9, and newer groups, launched in 2011-12.
Finally, looking at the growth vs size chart below,
we note a cluster of smaller and mostly older groups near the origin,
and a bunch of groups on the "frontier" of the chart that stand out,
either by their large size or their fast growth. Those are the groups in the 2 lists above.

Next, is the table with all the group membership and growth data.
