LinkedIn now has a group statistics dashboard that allows group admins to drill down into the demographics and growth of their groups.
The new dashboard displays data about each group in infographic-style displays: “Demographics”, “Growth” and “Activity”. The Group Statistics dashboard illustrates group growth, displays how many new members the group has gained in the last week and shows a graph of the group’s week-over-week growth. The “Activity” tab highlights how many discussions occurred within the group.
