Build charts in Amplitude: Add user segments

Events are only half of the equation. You also need to specify the users whose behavior you want to analyze.

Amplitude's Segmentation Module lets you create groups of users to analyze. These groups are called segments, and they can be as broad as your entire user base, or narrowly tailored to match a highly specific set of user properties.

Also, refer to the advanced features available through the Segmentation Module.

Create a user segment

First, decide which category of users your segment draws from: any users, active users, or new users.

If you select Any Users, your analysis includes all users who triggered the events you want to analyze. This is the broadest choice.

To narrow the focus, select Active Users. Amplitude defines an active user as one who logged at least one event during a specified time range. When you choose this option, Amplitude looks at events that any user triggered during the days, weeks, or months your analysis covers.

The New User option is more specific. Amplitude defines a new user as a user who logs an event in Amplitude for the first time. When you choose this option, Amplitude looks at events these users triggered during the interval (days, weeks, or months) in which the user was new.

For example, if a user was new on July 17, and you set your analysis interval to Daily, only the events that triggered on that same day, July 17, appear on the chart, regardless of whether that user also triggered events the next day.

You can use Accounts to select any custom groups you have instrumented in place of Users.

After you decide how to measure your users, use Filter by and Performed clauses to define your user segments.

You have now created your first user segment.

Filters

To learn how to use filters to refine your user segments into more precise analytical tools, refer to Modify a user segment.

Add more segments

Amplitude doesn't limit your analysis to a single segment. To add more segments, click + Add Segment. Here, there are two segments to compare: one that includes users in the United States, and one that includes users in Brazil.

Group by user property

The Segmentation Module also includes a Group Segment by function.

If you have only one event in your analysis, it doesn't matter if you use group by in the Events Module or Group Segment by in the Segmentation Module. But if your analysis includes more than one event, adding a Group Segment by condition in the Segmentation Module applies that condition to all the events in your analysis. If you don't want that, apply a group-by condition in the Events Module on an event-by-event basis.

Your chart displays the top five segments by the selected measurement. You can add or remove segments from the chart in the data table below it. In the example below, the analysis groups by device family. The graph shows the number of daily active users in the last 30 days, grouped by the device family they used.

You can also add more than one group by condition.

Save a user segment

After you create a user segment, you can save it for reuse in another analysis. Saved user segments are globally available to other team members.

To save a user segment, click Saved. Next, click Save Segment and follow the prompts.

You can also search for previously saved segments in the Saved dropdown. Select the one you need from the list to load it.

To make a segment your default segment (the one Amplitude automatically loads when you create a new chart), click Set as default next to the segment's name.
