Reddit is a discussion forum with topics covering a wide range of subjects, each known as subreddits.

Shown on the website are numbers of submissions to general and health subreddits.

We collect the data at an interval of 15 to 30 minutes. There is a balance between being up to date with new submissions, and having a list of submissions which the subreddit moderators have reviewed. Submissions can be deleted on the Reddit site by the original poster.

The Reddit API allows us to retrieve the past 1000 entries. Depending on how popular the subreddit is, the period for which data is available varies. Some subreddits can have more than 1000 entries every few hours, while for other subreddits this can represent a year's worth of contributions. Collection started in March 2024.
