A nationwide dataset of de-identified activity spaces derived from geotagged social media data

This repository introduces a _de-identified_ and _spatially aggregated_ user activity dataset in the United States, which contains approximately 2 million users and 1.2 billion data points collected from 2012 to 2019.

This data is stored in a series of [Parquet](https://github.com/apache/parquet-format) files, totaling 13GB, in the `data/parquet/` directory. A smaller subset with only points within the Denver timezone can be found in `data/sample/`.
