get_observations
Fetches observations for a statistical variable from Data Commons. **CRITICAL: Always validate variable-place combinations first** - You **MUST** call `search_indicators` first to verify that the variable exists for the specified place - Only use DCIDs returned by `search_indicators` - never guess or assume variable-place combinations - This ensures data availability and prevents errors from invalid combinations This tool can operate in two primary modes: 1. **Single Place Mode**: Get data for one specific place (e.g., "Population of California"). 2. **Child Places Mode**: Get data for all…
search_indicators
**Purpose:** Search for topics and variables (collectively called "indicators") available in the Data Commons Knowledge Graph. **Core Concept: Results are Candidates** This tool returns *candidate* indicators that match your query. You must always filter and rank these results based on the user's context to find the most relevant one. **Background: Data Commons Structure** Data Commons organizes data in two main hierarchies: 1. **Topics:** A hierarchy of categories (e.g., `Health` -> `Clinical Data` -> `Medical Conditions`). Topics contain sub-topics and member variables. 2. **Places:** A …
validate_child_place_types
Checks which of the child place types are valid for the parent place. Use this tool to validate the child place types before calling get_observations for those places. Example: - For counties in Kenya, you can check for both "County" and "AdministrativeArea1" to determine which is valid. i.e. "validate_child_place_types("Kenya", ["County", "AdministrativeArea1"])" The full list of valid child place types are the following: - AdministrativeArea1 - AdministrativeArea2 - AdministrativeArea3 - AdministrativeArea4 - AdministrativeArea5 - Continent - Country - State - County - City - CensusZipC…
