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 money supply changes.

Leading indicators include the index of consumer expectations, building permits, and the money supply. 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 Average weekly hours (manufacturing) — Adjustments to the working hours of existing employees are usually made in advance of new hires or layoffs, which is why the measure of average weekly hours is a leading indicator for changes in unemployment. Average weekly initial jobless claims for unemployment insurance — The CB reverses the value of this component from positive to negative because a positive reading indicates a loss in jobs. The initial jobless-claims data is more sensitive to business conditions than other measures of unemployment, and as such leads the monthly unemployment data released by the U.S. Department of Labor. Manufacturers' new orders for consumer goods/materials — This component is considered a leading indicator because increases in new orders for consumer goods and materials usually mean positive changes in actual production. The new orders decrease inventory and contribute to unfilled orders, a precursor to
