Economic variables include: gross domestic product, consumer price index, producer price index, employment indicators, retail sales and consumer confidence. These variables, also referred to as indicators, provide quantitative data about the state of an economy.
Gross domestic product is often considered the leading indicator of an economy and is a measure of the entirety of goods produced within a nation. The figures for gross domestic product are released quarterly and annually. The consumer price index is one indicator of inflation and measures the rate of increase in the cost of goods and services. Similarly, the producer price index measures the price of wholesale goods.
