360° Customer Profiles
Your stack is composed of 10+ tools. Each one has data about your customers; none have the full picture. With Census, unify that siloed data into a bespoke 360° customer profile that stays in sync across all tools, so your team doesn't have to go to 5 different places to understand their customers.
Custom Properties
Create granular segments or audiences based on any data so you can send personalized emails and messages, show ads to inactive users to reengage them, promote new features to users who will benefit the most, and many more use cases.
Synthetic Events
Are there holes in your tracking implementation? Need to capture an event after the fact? Census can send events based on interactions that are out of reach of your application and backfill event streams with historical data.

Where can Census sync to in Amplitude?
Device ID
Use the Identify API to set the User ID for a particular Device ID or update user properties of a particular user without sending an event.
User Profile API
The User Profile API serves Amplitude user profiles, which include user properties, computed user properties, a list of cohort IDs of cohorts that the user is in, and recommendations.
Group Identify API
Use the Group Identify API to set or update properties of particular groups. The Amplitude Accounts add-on makes analytical functionality available at the group level. A group is an object that a set of users might belong to, like a company of customers, team of users, or a playlist with listeners. Groups can help you understand how accounts interact with your product, instead of how individual users interact.
