Social class in the United Kingdom traditionally divides society into three main categories: the upper class, middle class, and working class. The upper class often includes aristocrats and wealthy individuals, while the middle class consists of professionals and skilled workers. The working class typically comprises those in manual labor or low-paying jobs. These classes can influence various aspects of life, including education, employment opportunities, and social networks. Factors such as income, occupation, and family background play significant roles in determining one's social class. The National Health Service and education system are examples of institutions that reflect and sometimes challenge these class distinctions.
