Since the 2025 administration change, disappearing federal datasets have sparked widespread concern – and confusion.
Today, dataindex.us published the Federal Data Terminations Tracker – the most policy-relevant, verified source of federal datasets terminated since January 2025. Having evolved from the crowdsourced Dearly Departed Datasets published in October 2025, the tracker combines community reporting with expert identification and review to provide a regularly updated record of terminations.
The team identified dozens of federal datasets and hundreds of data elements that have been terminated – significantly fewer than other reports, but more tailored to informing effective public engagement and future data policies needed to run a modern society.
