Demographic decline refers to the reduction in the size of a population and/or a decrease in the proportion of younger age groups within that population. This phenomenon is often caused by consistently low birth rates, increased mortality rates, and emigration, leading to an aging population and a shrinking workforce. In the context of cybersecurity, demographic decline can impact the availability of skilled professionals, potentially increasing vulnerabilities due to workforce shortages. It can also affect the adoption of new technologies and the resilience of organizations to cyber threats, as fewer young people may be available to fill critical roles.
