Work with Data Commons, a platform providing programmatic access to public statistical data from global sources. Use this skill when working with demographic data, economic indicators, health statistics, environmental data, or any public datasets available through Data Commons. Applicable for querying population statistics, GDP figures, unemployment rates, disease prevalence, geographic entity resolution, and exploring relationships between statistical entities.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Data Commons Client ## Overview Provides comprehensive access to the Data Commons Python API v2 for querying statistical observations, exploring the knowledge graph, and resolving entity identifiers. Data Commons aggregates data from census bureaus, health organisations, environmental agencies, and other authoritative sources into a unified knowledge graph. ## Installation Install the Data Commons Python client with Pandas support: ```bash uv pip install "datacommons-client[Pandas]" ``` For basic usage without Pandas: ```bash uv pip install datacommons-client ``` ## Core Capabilities The Data Commons API consists of three main endpoints, each detailed in dedicated reference files: ### 1. Observation Endpoint - Statistical Data Queries Query time-series statistical data for entities. See `references/observation.md` for comprehensive documentation. **Primary use cases:** - Retrieve population, economic, health, or environmental statistics - Access historical time-series data for trend analysis - Query data for hierarchies (all counties in a state, all countries in a region) - Compare statistics across multiple entities - Filter by data source for consistency …

How to install
mdr add marielynneblock/arcanum-artifex/datacommons-client@sha256:67eb7cd669879e61The line at the top of this page pins the label git:20260710.0115f49, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
