Community size

Community Size metrics show the current size of your community, as well as loss and growth trends over time. Use community size metrics to plan upcoming recruitments and identify any anomalies in the number of members lost that need be investigated.

Note: This report represents member data only and does not include nonmember data.

To access the Community Size page, click the App Drawer and select Health Metrics > Community Size.

By default, Community Size metrics show the current size of your community, plus trends from the previous six months. Use the Time Range selector to change the period and see the total number of members gained, lost and the net change over the selected time period (3, 6, 12, or 18 months).

If you have multiple communities, the size metrics show the combined number of members and loss/gain statistics for all communities. To view the metrics for one community at a time, use the community variable to filter your data. For more information, see Filter community metrics.

Community size metrics

The Community Size chart shows the number of members joining and leaving the community over time. As you hover over a trend line, a dialog shows the number of members Lost and Gained, as well as the Total Size for the specific month.

The following table describes the trend lines in the Community Size metrics:

Trend line	Description
Total Size	The count of distinct members where the member status is Active by the end of the given month, or the current month.
Gained	The count of distinct members where the member status is Active by the end of the given month, or the current month and the member status did not exist or was not Active at the end of the previous month.
Lost	The count of distinct members where the member status is Undeliverable, Unsubscribed or Purged at the end of the given month or the current month and the member status was Active at the end of the previous month.

Loss Analysis chart

The Loss Analysis chart shows trends of member loss over time. As you hover over a data point on the trend line, a tooltip shows the count for each Purged, Undelivered, or Unsubscribed status for the specific month.

The following table describes the trend lines in the chart:

Trend line	Description
Purged	The number of times members were removed from the community.
Undelivered	The number of times members did not receive invitations because email delivery failed or because a spam complaint was made.
Unsubscribed	The number of times members who no longer want to receive emails from the community requested removal from the community.

Note: A member who is lost multiple times will be counted multiple times if the member's latest status is active and not nonmember. If a member becomes a nonmember, the following loss statuses such as purged, undelivered, and unsubscribed will not be counted. They will only count in the Loss Analysis chart if the member's latest status is active.

Example

The following are examples of how changing a member's status can affect whether the loss is counted in the Loss Analysis chart.

Member Status	Description
Active	If John is active, unsubscribed, and purged in a given month, that will be counted as 1 Purged and 1 Unsubscribed loss.
Nonmember	If John is active, becomes a nonmember, and is purged and unsubscribed in a given month, none of the losses will be counted since John became a nonmember before getting purged and unsubscribed.
Active, nonmember, and then reactivated	If John is active, and then becomes a nonmember, is purged, reactivated and then undeliverable, only the 1 Undeliverable loss will be counted since John has to be active before it can count.

Why Members Are Unsubscribing

The Why Members Are Unsubscribing chart shows the reasons selected in the unsubscribe study by active members or participants who unsubscribe from the confirmation email. Selecting a reason is not mandatory when members unsubscribe.

To view the text answers with the Other/Specify option, click Responses for Other/Specify. You can also use the Find field to search for keywords and phrases in Other/Specify answers.

Note: The Why Members Are Unsubscribing chart applies to new customers only. Upgraded customers will export data from the Unsubscribe Study.

Note: You may see discrepancies in your Why Members Are Unsubscribing chart. For more information, see Discrepancies in Community Metrics.

At the right side of the page, the Community Size value shows the total number of members marked with status of Active currently in the community. An Active member is a community member who can be invited to participate in activities.

Time Range

By default, Community Size metrics show the current size of your community, plus trends from the previous six months. Use the time range selector to change the period and see the total number of members gained, lost and the net change over the selected time period.

The following table describes the counts in the Time Range area of the metrics:

Metric	Description
Gained	The total number of members gained for the specified time period, regardless of whether a new member subsequently unsubscribes, becomes undeliverable, or is purged from your community.
Lost	The total number of members that unsubscribed, became undeliverable, or were purged from your community for the specified time period.
Total	The net change in the community size for the specified time period (total Members Gained minus total Members Lost). An up arrow indicates there has been an overall net gain of X number of members for the specified time period. A down arrow indicates there has been an overall net loss of X number of members for the specified time period.

To set the time range, click the selector to expand the list, and select a time period.

To create a custom time range:

Click the time range selector, and select Custom.
In the Set Custom Time Range dialog that appears:
1. Set the start Month and Year.
