A filtered dataset is a subset of submitted data that satisfies certain conditions set by the user. Filtered datasets are helpful when you need to share a dataset with other users, yet want to keep certain fields or records private that are repetitive, irrelevant or sensitive.
Suppose you carried out a baseline survey on households in several drought-stricken states, and you would like to have local analysts access data that’s only from their individual state. In this case, you could create multiple filtered datasets (one from each state) that segment data from each state — no external tools needed.
If the data is sensitive, the filtered datasets can go into unique projects that are selectively shared with specific users. If the data is not sensitive and you just wanted to make the data easier to understand, all of the filtered datasets can go into the same project.
