Data Sources

RDS Explorer

Explore the Data

Use the RDS Explorer to browse the data, consult the codebook, create custom extracts by filtering records and selecting variables, or produce personalized open data packages for download.

The tool can also be used by developers and data scientists to generate API calls or source code for instantly reading the data into analytical tools, creating visualizations, and for other purposes.


Aggregate the Data

Use the RDS Tabulation Engine to aggregate data across various dimensions to rapidly create analytical tables. Start from scratch, or select from the following examples:

Donald Trump approval of job as president by race
Trump's chance of winning North Carolina by date
Comparison of 2016 voters and who they will vote for in 2020
RDS Tabulation Engine

The tool can also be used by developers and data scientists to generate API calls or source code for instantly reading the data into analytical tools, creating visualizations, and for other purposes.


Use RDS Web Services / API

RDS was designed for data scientists and developers. Making data and metadata available as a service is essential for enabling access by applications and is a fundamental benefit of our platform. To get started, consult our Public Data Center Postman Documentation or the RDS API technical specifications. And you can leverage our open source GitHub hosted libraries for JavaScript, Python, and R, to rapidly integrate data and metadata in web portals, create storytelling visualizations, machine learning, linking, or any other analytical purposes.

For technical assistance, visit our RDS Helpdesk, join our RDS Slack workspace, or contact us directly.

About Project

Through this Public Data Center, we hope to both make highly sought-after data available, and demonstrate the benefits of combining modern technologies and metadata to empower informations system. Our Rich Data Services platform is the result of years of R&D, experience working with data, and collaboration with agencies and users worldwide. We believe that making data available as a service (API) is fundamental to meeting the needs of developers and data scientists, and delivering self-service tools to traditional researchers or casual users.
