Open access data is data that is available to use at no cost, freely accessible, and downloadable. SPARC has defined Open Data as "research data that is freely available on the internet permitting any user to download, copy, analyze, re-process, pass to software or use for any purpose without financial, legal, or technological barriers." However, be sure to cite where and how you accessed your data.

The list below includes links to government and other open access repositories that contain datasets with an age or aging component. Consider how adding an open access data analysis component may help you to broaden your current research program. Even something as simple as examining how often people search for aging information on the internet and how that may compare to previous years (Google Trends). You could examine how opinions of healthy aging have changed over the years in Canada (Canadian Opinion Research Archive) or the average age of refugee claimants (OpenICPSRStatistics Canada).

You may also want to share data from your own past research in an open access repository. If you are at a Canadian institution, you can deposit your data in the Federated Research Data Repository (FRDR).

  • DataCite

    DataCite is a leading global non-profit organisation that provides persistent identifiers (DOIs) for research data and other research outputs. Organizations within the research community join DataCite as members to be able to assign DOIs to all their research outputs. This way, their outputs become discoverable and associated metadata is made available to the community. DataCite then develops additional services to improve the DOI management experience, making it easier for our members to connect and share their DOIs with the broader research ecosystem and to assess the use of their DOIs within that ecosystem. DataCite is an active participant in the research community and promotes data sharing and citation through community-building efforts and outreach activities.

    The Dryad Digital Repository is a curated resource that makes research data discoverable, freely reusable, and citable. Dryad provides a general-purpose home for a wide diversity of data types. Dryad originated from an initiative among a group of leading journals and scientific societies to adopt a joint data archiving policy (JDAP) for their publications, and the recognition that open, easy-to-use, not-for-profit, community-governed data infrastructure was needed to support such a policy. These remain our guiding principles. Dryad’s vision is to promote a world where research data is openly available, integrated with the scholarly literature, and routinely re-used to create knowledge. Our mission is to provide the infrastructure for, and promote the re-use of, data underlying the scholarly literature.
