The middle class is a key factor of stability for any country. Aristotle pointed out that the bigger the middle class – or social group between rich and poor – the more stable the society is. The veracity of this statement is especially clear in modern society, where the middle-class acts as an engine of economic growth and social progress. Due to the aforementioned, it is difficult to overestimate the importance of a study of the quantitative dimension of the middle class and its developmental tendencies, especially in countries with transitional economies – like Georgia – that have acquired sovereignty and undertaken the path for development of the market economy relatively recently.
