The very nature of social policy is that it poses to be very simplistic if one aspect is considered but proves to be very complex if it is looked as a whole. To understand the complex concept of social policy, we have very limited sources. Here lies the relevance of this textbook.. As the name "understanding theories and concepts in social policy" suggests, this book explains the concept of social policy as a whole. Humans are constantly in pursuit of improving and developing their lives. This is clearly evident as man constantly reforms the areas of education, health care, labor, criminal justice, and social care among many others. This textbook outlines the broad scope of social policy as an area of study and introduces the reader to major theories and concepts within the discipline of social policy. It critically examines theoretical approaches such as Liberalism, Marxism, Social Democracy, neo-liberalism, post-modernism etc. as well as approaches from the perspective of social movements, especially feminism. In addition to that, the book also discusses sensitive topics, which are important part of social policy, like community and citizenship, equality and social justice, needs, liberty and freedom, and challenges and future directions. The central theme of this book is to develop an understanding of the links between social policy theory, ideology, policy, and politics and practice so that readers can see the relevance to their own lives. It also explores different perspectives and visions on social policy and their implications for understanding and addressing major social problems in society. Central to the current study of social policy is the recognition that society is divided by differences such as age, gender, income, ethnicity and so forth.
