Ontario Data Documentation, Extraction Service and Infrastructure Initiative (<odesi>)

Established in 2007, <odesi> (Ontario Data Documentation, Extraction Service and Infrastructure) is a digital repository for social science data, including polling data. It is a web-based data exploration, extraction and analysis tool that uses the Data Documentation Initiative (DDI) social science data standard.

<odesi> provides researchers the ability to search for survey questions (variables) across hundreds of datasets. The data is in different formats, such as microdata, Excel and B2020 files.

New data in ODESI contains over 5,600 datasets for the social sciences, with more than 22,700 additional dataset descriptions available for searching.
