 # SynthPops
 
-SynthPops is a module designed to generate synthetic populations that are used for COVID-19 (SARS-CoV-2) epidemic analyses. SynthPops can create generic populations with different network characteristics, as well as synthetic populations that interact in different layers of a multilayer contact network. **Note**: SynthPops is currently under active development and most features are fully tested and documented, but not all. We are in the process of expanding to include data and validation on additional regions beyond the original scope of the Seattle-King County region of Washington, USA. At the moment we have data for the following locations (in the synthpops/data folder) :
