measures their magnitude for demand and understanding the process of consumer buying behaviour to formulate products and services, pricing, promotion and distribution to satisfy these needs and wants through exchange processes and building long-term relationships. Political economy is the study of production, buying and selling, and their relations with law, custom, and government. Public administration is one of the main branches of political science, and can be broadly described as the development, implementation and study of branches of government policy. The pursuit of the public good by enhancing civil society and social justice is the ultimate goal of the field. Though public administration has been historically referred to as government management, it increasingly encompasses non-governmental organizations (NGOs) that also operate with a similar, primary dedication to the betterment of humanity. Religious studies and Western esoteric studies incorporate and inform social-scientific research on phenomena broadly deemed religious. Religious studies, Western esoteric studies, and the social sciences developed in dialogue with one another. Methodology Social research The origin of the survey can be traced back at least early as the Domesday Book in 1086, while some scholars pinpoint the origin of demography to 1663 with the publication of John Graunt's Natural and Political Observations upon the Bills of Mortality. Social research began most intentionally, however, with the positivist philosophy of science in the 19th century. In contemporary usage, "social research" is a relatively autonomous term, encompassing the work of practitioners from various disciplines that share in its aims and methods. Social scientists employ a range of methods in order to analyse a vast breadth of social phenomena; from census survey data derived from millions of individuals, to the in-depth analysis of a single agent's social experiences; from monitoring what is happening on contemporary streets, to the investigation of ancient historical documents. The methods originally rooted in classical sociology and statistical mathematics have formed the basis for research in other disciplines, such as political science, media studies, and marketing and market research. Social research methods may be divided into two broad schools: Quantitative designs approach social phenomena through quantifiable evidence, and often rely on statistical analysis of many cases (or across intentionally designed treatments in an experiment) to create valid and reliable general claims. Qualitative designs emphasize understanding of social phenomena through direct observation, communication with participants, or analysis of texts, and may stress contextual and subjective accuracy over generality.
