Several countries are currently experiencing increasing income inequality, which has, among other things, important implications for the insurance sector, as the group of vulnerable individuals who cannot afford insurance is growing. The society expects solutions from insurance companies in terms of risk management even for the population from the lowest income classes. The question is, however, what are the possibilities for the development of a niche product intended for the socially deprived? To answer this question, it is crucial to evaluate the extent and the factors of non-insurance. An analytical assessment of the insurance gap will enable insurance companies to develop new niche products aimed at the socially weaker and thus enlarge their client pool. Moreover, by more actively addressing the insurance gap, insurance companies will take an important step forward in the fields of sustainability and social responsibility, which are becoming an increasingly important competitive advantage in the insurance industry all around the globe.
