This presentation and resource list is from the HSx Homeland Security Course on Major Economies Confront Shrinking Workforce. "While not exhaustive, the following resources provide a roadmap to understanding primary drivers of change in the space, both through commercialization and national security. These resources provide a baseline of understanding, but as space capabilities continue to evolve, new data will become available and resource lists will require updates." Advanced Thinking in Homeland Security (HSx) is an 18-month collaborative program from the Center for Homeland Defense and Security.
