They may study the way of life, archaeological remains, language, or physical characteristics of people in various parts of the world. Some compare the customs, values, and social patterns of different cultures. Anthropologists generally concentrate in sociocultural anthropology, archaeology, linguistics, or biological-physical anthropology. Sociocultural anthropologists study the customs, cultures, and social lives of groups in settings that vary from nonindustrialized societies to modern urban centers. Archaeologists recover and examine material evidence, such as tools and pottery remaining from past human cultures, in order to determine the history, customs, and living habits of earlier civilizations.
Linguistic anthropologists study the role of language in various cultures.
Biological-physical anthropologists study the evolution of the human body, look for the earliest evidences of human life, and analyze how culture and biology influence one another. Most anthropologists specialize in one particular region of the world. Economists study the production, distribution, and consumption of goods and services. Most economists are concerned with the practical applications of economic policy in a particular area, such as finance, labor, agriculture, transportation, energy, or health. Others develop theories to explain economic phenomena such as unemployment or inflation.
