Economists study the production, distribution, and consumption of commodities and services. They may conduct surveys and analyze data to determine public preferences for these 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. Geographers study the distribution of both physical and cultural phenomena on local, regional, continental, and global scales.
Geographers specialize, as a rule.
Economic geographers study the regional distribution of resources and economic activities. Political geographers are concerned with the relationship of geography to political phenomena local, national, and international. Physical geographers study the distribution of climates, vegetation, soil, and land forms. Urban and transportation geographers study cities and metropolitan areas, while regional geographers study the physical, climatic, economic, political, and cultural characteristics of regions, ranging in size from a congressional district, to a State, country, continent, or the entire world. Medical geographers study health care delivery systems, epidemiology, and the effect of the environment on health.
