In addition to building demographic models and parameterizing them with field data, I am a member of the Science Committee for the twin databases of matrix population models, COMPADRE and COMADRE. Our goal is to enable comparative demographic studies by assembling a comprehensive database of demographic models and their associated metadata, then making it publicly available along with tools to work with the data.
See our blog for highlights of recent papers that have resulted from this effort, or download the latest versions of each dataset here.
