# Department workforce trends

## Description

A **Department trend** event tracks when a company increases or decreases staffing within a specific department. This data helps monitor employment trends, workforce restructuring, and organizational growth or downsizing.

**Important:** The **Department Trend** event tracks **only recent workforce distribution changes**. If no changes occurred within the last quarter (`timestamp_from` should be set to the past 3 months), no data will be returned.

**For a historical workforce analysis,** use the **Workforce Trends Enrichment API**.

## Use cases:

* **Labor Market Analysis**: Identify hiring or downsizing trends within industries.
* **Competitive Intelligence**: Track workforce changes in competitor organizations.
* **Economic Indicators**: Assess how staffing changes affect regional and industry employment.
* **Business Strategy**: Understand how companies adjust their workforce for growth or cost-cutting measures.

## Data Schema

**Event Name: "increase\_in\_\<department>" or "decrease\_in\_\<department>" (Use these values in the event\_types parameter when querying workforce change events per department. Replace \<department> with the actual department name.)**

  "https://api.explorium.ai/v1/businesses/events" \
  -H "API_KEY: your_api_key_here" \

## Best Practices

* **Filter by department (`department`)** to track workforce changes in specific fields.
* **Monitor change type (`change_type`)** to distinguish between hiring and downsizing trends.
* **Use timestamps (`event_time`)** to analyze trends over time.
