Economics is often called the science of decision making. The decisions that economists analyze range from personal decisions such as how big a pizza to order or whether to buy or lease a new car to the decisions the federal government makes about things like the size of our military. Economists use information about these, and other decisions, to develop indicators that can be used to determine the health of our economy. Just as a physician relies on indicators such as temperature, blood pressure and heart rate to determine the health of a patient, economists use indicators like gross domestic product growth, the unemployment rate and the rate of inflation to predict our nation's economic health.
