Shadow Government® uses T21-USA as an engine for its simulations. Threshold 21 (T21) is a dynamic simulation tool designed to support comprehensive, integrated long‐term country planning. The model has been developed by the Millennium Institute and is the result of more than 20 years of extensive research and application carried out in consultation with the World Bank, UN agencies, developing country governments, and nongovernmental organizations.

T21 integrates economic, social, and environmental factors in its analysis, thereby providing insight into the potential impact of development policies across a wide range of sectors. It reveals how different strategies interact to achieve desired goals and objectives.
