Note: There is a lot of overlapping between the concepts of Societal Resilience, Social Resilience and Community Resilience.
The IMPROVER project  gives the following definition:
The ability of a community or society exposed to hazards to resist, absorb, accommodate to and recover from the effects of a hazard in a timely and efficient manner, including through the preservation and restoration of essential basic structures and functions. (Adapted by UNISDR
Note: This definition refers to CI-related organisations. The IMPROVER recognises also two other dimensions which are relevant for CI, namely Technological Resilience and Organisational Resilience.
Ability of human groups or communities to cope with external stresses and disturbances as a result of social, political and environmental change. 
The way in which individuals, communities and societies adapt, transform, and potentially become stronger when faced with environmental, social, economic or political changes. 
[Resilience refers to] the adaptive and learning capacity of individuals, groups and institutions to self-organise in a way that maintains system function in the face of some change or in response to any disturbance. 
Social resilience is comprised of three dimensions : (i) coping capacities - the ability of social actors to cope with and overcome all kinds of adversities; (ii) adaptive capacities - their ability to learn from past experiences and adjust themselves to future challenges in their everyday lives; (iii) transformative capacities - their ability to craft sets of institutions that foster individual welfare and sustainable societal robustness towards future crises.
