Social sciences involve the systematic study of human society and relationships between members of society. It includes disciplines like sociology, psychology, anthropology, economics, and political science.
Applied social science is the application of theories, concepts, and findings from social sciences to address real-world problems and issues. It aims to help groups of people improve their lives by applying knowledge from social science disciplines.
The key difference is that social sciences focus on developing concepts and understanding society, while applied social sciences integrate this knowledge to analyze and solve issues in the actual world.
