Overview

HDX Signals monitors key datasets and generates automated emails when significant, negative changes are detected. Signals are identified for given datasets and locations.

Over 200 locations are monitored, with coverage varying depending on the dataset. The following table details the number of locations covered by each dataset:

Datasets	Number of locations
Agricultural hotspots	81
Conflict events	188
Food insecurity	53
Internal conflict-driven displacements	82
Internal disaster-driven displacements	199
Market monitoring	80

We use a thresholds approach to identify when a signal should be created in a given dataset. The specific methodology for each dataset is detailed in the "Datasets" section of this site. We only send a signal if it has been detected in the past sixty days and if no identical signal was detected in the past six months.
