Economic and Human Consequences
The fundamental metrics for consequence assessment in NISAC analyses
are population and economic impact. NISAC uses a mixture of proprietary
commercial software and in-house modeling and simulation capability
to provide first-in-class estimates of these impacts.
- Social Vulnerability Analysis
A key aspect of a community's resilience in the face of a disaster is
its inherent social vulnerability. Social vulnerability
is defined in terms of the demographic characteristics that are known
to increase the likelihood of negative outcomes following a disaster.
These factors include workforce participation, race and ethnicity, age
of population, poverty, household characteristics, and percentage of
population in rural and urban locations. NISAC estimates socioeconomic vulnerability
using the Social Vulnerability Index (SoVI) methodology.
- Economic Analysis
During emergency events, DHS and other agencies need rapid turnaround
analyses of the potential economic impacts from a disaster and other
events that can affect infrastructure systems. NISAC's FastEcon geospatial
tool measures economic impacts incurred in any area of the United States.
FastECON can quickly analyze threats to our nation’s economy and identify
economically vulnerable locations.
- Population Analysis
NISAC uses a suite of agent-based modeling tools to assess the
potential affects of disasters, pandemics,and transportation disruptions
(among others) on the Nation's population. NISAC's suite of tools includes
the Agent Framework Simulation model, ActivitySim, EpiSimS, and HURT.
