How do I look up specific variables like median income?

The skill can query the variables.json endpoint or use built-in reference lists to find specific codes like B19013_001E for median household income.

What is the difference between ACS 1-year and 5-year data?

ACS 1-year data is best for recent trends in large areas (pop 65k+), while ACS 5-year data is more reliable for smaller geographies like census tracts and block groups.

Do I need an API key to use this skill?

While the Census API allows limited testing without a key, you should register for a free key at api.census.gov to avoid rate limits and enable production-level data requests.

Can this skill help me find specific FIPS codes?

Yes, the skill provides guidance on geography predicates and hierarchy, helping you correctly identify and filter by state, county, and tract FIPS codes.

Ciencia de Datos y ML

Streamlines the retrieval of demographic, economic, and housing data from the US Census Bureau API.

Acerca de

The US Census Data skill enables developers and researchers to programmatically access official US demographic and economic statistics. It simplifies the complex Census API ecosystem by helping users select the appropriate datasets—including the American Community Survey (ACS) and the Decennial Census—while assisting with variable lookups and geographic FIPS code filtering. From fetching state-level population estimates to granular block-group housing data, this skill manages the entire workflow from API key configuration to query construction and error handling.

Características Principales

Support for complex geographic nesting and FIPS code filtering.
Integrated guidance on Margins of Error (MOE) and data reliability.
Environment variable management for CENSUS_API_KEY security.
Intelligent variable lookup for demographic, income, and housing metrics.
Automated API query construction for ACS, Decennial, and Population Estimates.
1 GitHub stars

Casos de Uso

Integrating official US population statistics into local government or non-profit applications.
Building demographic dashboards for market research and urban planning.
Automating the collection of socio-economic data for data science projects.
