Aggregated mobility and density data for the Netmob 2024 Data Challenge

This includes data from Spectus, a data clean room for human mobility analysis, which has been aggregated at the Geohash 3 and Geohash 5 level for four countries, Colombia, Mexico, Indonesia and India. Two types of datasets are included, one that has density (number of unique devices within a geohash 3/5 area), and one that has origin-destination matrices with data on number of trips between geohash 3/5 areas. Spectus data is collected with the informed consent of anonymous users who have opted-in to anonymized data collection for research purposes. In order to further preserve the privacy of users, no individual-level data has been shared for this challenge. Spectus data has been aggregated to Geohash 3 and Geohash 5 level, with a minimum threshold of 10 unique anonymous devices per spatiotemporal unit.
