Review Census measure references when a research schema changes
A changed research schema can trigger a definition check for Census measures affected by the update.
Trigger
Data Source Schema Updated
Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
Action
Get Variable Details
Tool to retrieve metadata for a specific variable in a census dataset for a given year. use when you need the label, concept, data type, attribute codes, and valid-value constraints.
Why this helps
Renamed or removed research fields can quietly break shared understanding of the measures a team tracks.
- Prompts a definition review when research structure changes.
- Helps keep measures understandable as a database evolves.
- Makes structural updates easier to follow up on.
Setup
Build it in a few focused steps.
- 1Connect Notion and Census bureau to Notis once.
- 2Create the automation in the portal or ask Notis to set it up conversationally.
- 3In one instruction, ask Notis to retrieve variable details for Census measures clearly implicated by relevant schema changes, with dataset and year context.
- 4Choose Data Source Schema Updated, select a reporting channel, and test by making a real schema change tied to a Census measure.
Questions about this workflow
What kinds of schema changes trigger it?
The event fires when a data source schema is updated, such as a column being added, removed, or renamed.
Why scope the prompt carefully?
A schema change may be unrelated to Census data. The instruction should request a lookup only when the changed field maps clearly to a measure.

Supported Triggers and Actions
Notis builds workflows that link Notion to Census bureau. A trigger fires from one place; an action lands in another.
Notion triggers
Census bureau actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Get ACS 1-Year Estimates
Tool to retrieve 1-year american community survey (acs) estimates for a specified geography. use when you need the most recent annual acs data for a given area.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Get ACS 5-Year Estimates
Tool to retrieve 5-year american community survey estimates for a specified year. use when detailed acs data by geography and variables is required.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Get American Business Survey
Tool to retrieve annual business survey (abs) data for a specified year and endpoint.
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
Get Community Resilience Estimates
Tool to retrieve community resilience estimates for a specified year. use after selecting variables and geography to get cre data for analysis.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Get County Business Patterns
Tool to retrieve county business patterns (cbp) data for a specified year. use when you need county-level business establishment and employment statistics filtered by industry and geography.
Database Created
Triggers when a new Notion database (the container) is created. A database is the post-2025-09-03 container that holds one or more data sources. This trigger fires for the container's creation event (`database.created`), distinct from `NOTION_DATASOURCE_CREATED` which fires when a new data source is added to an existing database. Most customers calling Notion's `POST /v1/databases` (the legacy API) or creating a database via the Notion UI will see this event. Adding a new data source to an existing database fires `data_source.created` instead — use `NOTION_DATASOURCE_CREATED` for that. Notion's payload puts `entity.type: "block"` (the container is a `child_database` block in the content tree) and `entity.id` is the database id.
Get Decennial Census Data
Tool to retrieve decennial census data for a specified vintage and dataset. use when you need census variables for a given geography.
Data Source Created
Triggers when a new Notion data source is created. Fires workspace-wide. The payload's `data.parent` carries the data source's tree parent (typically the teamspace) for downstream filtering. A single template-based database creation can fire multiple `data_source.created` events at once — one per data source the template instantiates.
Get Population Estimates
Tool to retrieve population estimates program (pep) data for a specified vintage and dataset. use when you need population or demographic estimates for specific geographies.
Data Source Schema Updated
Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
Get Variable Details
Tool to retrieve metadata for a specific variable in a census dataset for a given year. use when you need the label, concept, data type, attribute codes, and valid-value constraints.
