 internal sources of change. So in this session, we are going to highlight various sources of change that play important and critical role at internal level, like the shifting of population. Shifting of population means that when population tends greatly affects social structure and social organization, the increase in population size, the migration of masses, then it can cause the towards the social change. Population in any place is considered very important in any area. When the population is growing much and much, then definitely the growing population, the traditional trends of society, almost every society, they are under change. Because as the population increases, new trends, new demands are born in the society. Now to adjust the new population, new numbers are made, new populations are made, new people migrate from one place to another. To settle those people, when new colonies migrate to new cities, then social change is the component part of this whole development. Then technological innovation. Now along with time, the more technological innovation comes, now it is not necessary that the duty will meet each other, then we will meet. Now through technological advancement, through technological innovation, the link that is connected to each other, which is communication, changes are taking place in it, then the impact of that is definitely coming over social change. We have seen a very clear example of this, that when the world had to face COVID, then under this pandemic situation, the method of getting education, the traditional method, the virtual learning was focused on it. And because of this virtual learning, the world was getting in contact with each other. When Sir Hadeh was formed, TravelBand was formed, and other resources of the movement were formed, transportation was formed, so people were getting in contact with each other and learning was also going on. Then new ideas and cultural values, definitely the cultural values with the help of the new ideas, it is an important source of change. We all know that in the developed world, they are trying to introduce their cultural supremacy to the developing world, the cultural supremacy in the name of their brands, in the name of their clothing, even in the food items. Now, it is not that there is one thing in the world, and the developed countries, if they have economic resources, then they are not in their excess. The influence of culture is spreading so rapidly that you can order everything online and you can order everything online. Another source of change is Diffusion. Diffusion refers to the process by which change comes about as culture spreads from one society to another through direct or indirect. Now, the concept of Diffusion is directly linked with the cultural exchange. Now, cultural exchange happens through planning, and Diffusion is indirectly affecting our minds, and what affects our minds definitely brings the change. For example, we go to buy things in the market. Now, from many days, we are looking at its advertisement on the media. Otherwise, our relationship with it would not be established. Now, the advertisement campaign is repeatedly on the media. After watching it, our mind necessarily forces our hands to pick up these things. So, what is this indirect cultural diffusion that the developed countries, in terms of planning, the countries that are not very advanced yet, are convincing people to create their own market there, and people are becoming a part of them, including their culture, their market, and their economy.
