An economic indicator is a statistic about an economic activity. Economic indicators allow analysis of economic performance and predictions of future performance. One application of economic indicators is the study of business cycles. Economic indicators include various indices, earnings reports, and economic summaries: for example, the unemployment rate, quits rate (quit rate in American English), housing starts, consumer price index (a measure for inflation), inverted yield curve, consumer leverage ratio, industrial production, bankruptcies, gross domestic product, broadband internet penetration, retail sales, price index, and changes in credit conditions. The leading business cycle dating committee in the United States of America is the private National Bureau of Economic Research. The Bureau of Labor Statistics is the principal fact-finding agency for the U.S. government in the field of labor economics and statistics. Other producers of economic indicators includes the United States Census Bureau and United States Bureau of Economic Analysis.

Classification by timing

Economic indicators can be classified into three categories according to their usual timing in relation to the business cycle: leading indicators, lagging indicators, and coincident indicators.

Leading indicators

Inflation data.webp is a leading indicator, CPI and PCE lag ]] Leading indicators are indicators that usually, but not always, change before the economy as a whole changes. They are therefore useful as short-term predictors of the economy. Leading indicators include the index of consumer expectations, building permits, and credit conditions. The Conference Board publishes a composite Leading Economic Index consisting of ten indicators designed to predict activity in the U. S. economy six to nine months in future. Components of the Conference Board's Leading Economic Indicators Index: Economist D.W. Mackenzie suggests that the ratio of private to public employment may also be useful as a leading economic indicator.

Lagging indicators

Lagging indicators are indicators that usually change after the economy as a whole does. Typically the lag is a few quarters of a year. The unemployment rate is a lagging indicator: employment tends to increase two or three quarters after an upturn in the general economy.. In a performance measuring system, profit earned by a business is a lagging indicator as it reflects a historical performance; similarly, improved customer satisfaction is the result of initiatives taken in the past. The Index of Lagging Indicators is published monthly by The Conference Board, a non-governmental organization, which determines the value of the index from seven components. The Index tends to follow changes in the overall economy. The components on the Conference Board's index are:

Coincident indicators

Coincident indicators change at approximately the same time as the whole economy, thereby providing information about the current state of the economy. There are many coincident economic indicators, such as Gross Domestic Product, industrial production, personal income and retail sales. A coincident index may be used to identify, after the fact, the dates of peaks and troughs in the business cycle. There are four economic statistics comprising the Index of Coincident Economic Indicators: The Philadelphia Federal Reserve produces state-level coincident indexes based on 4 state-level variables:

By direction

There are also three terms that describe an economic indicator's direction relative to the direction of the general economy:

Local indicators

Local governments often need to project future tax revenues. The city of San Francisco, for example, uses the price of a one-bedroom apartment on Craigslist, weekend subway ridership numbers, parking garage usage, and monthly reports on passenger landings at the city's airport.
