 social class, ethnicity, gender, age, we are going to highlight these topics in this session. What is social class? Social class refers to deviance in society based on economic and social status. People in the same class typically share a similar level of wealth, educational achievements, type of job and income. Now what is social class? Social class reflects the deviance of people in society where their income or social status is almost the same. Especially if based on education, money, or achievements or the nature of the job, if they are at the level of wealth, then they represent a particular type of social class. In the social class, because this is a larger group and people have similar positions, so there are different dimensions of social classes. So in every society in the world, whether the political system of any kind, society actually represents various social classes and normally the categories, the basic factors behind are commonly known as I have already told you that what type of and which amount of income and how much wealth you are having, then what is your position? What is your status? What is your profession? What is your education? What is your ethnic identity? Because ethnicity is a concept referring to a shared culture and a way of life. This can be reflected in language, religion, material culture such as clothing and cuisine and cultural products such as music and art. Ethnicity is often a major source of social cohesion as well as social conflict. What is the importance of ethnicity? It is reflected in the last line that ethnic groups which are especially related to each other, can also be social cohesion because of these groups, i.e. in the society there can be a lot of anxiety. But along with that, some social conflicts are also born because of ethnicity. Why do they take birth? When an ethnic group thinks that it is dangerous somewhere or is trying to dominate another group, then there are social issues born and then the situation of social conflict is created. Same we can discuss about gender. Gender refers to the characteristics of women, men, girls and boys that all are socially constructed. These include norms, behaviors and roles associated with being a woman, man, girl or boy as well as relationship with each other. As a social construct, gender varies from society to society and can change over time. When we talk about gender, all the representatives are included in this. Those who have a special gender are also a part of this. We are not just talking about men or women. We are talking about all the people who are reflecting on their identity in the society. What is the relationship between all of them? Everyone is important in the construction of the society. Social construction is only possible if there is such an interaction between all of them that the society can take it smoothly. Another important thing is the age stratification. Age stratification is a new concept in this context. There are a lot of states that call themselves welfare states where after reaching a certain age, when a person becomes less or his income is less, they look after those states but there are a lot of systems where you have to manage your life so age stratification is also an important factor where you have to talk about the outside world and this debate needs to be raised in a better way.
