The lagging indicators index is comprised of economic statistics that reflect economic activity after it has occurred. The seven lagging indicators are unemployment, unit labor costs for manufacturing, the average prime rate charged by banks, the ratio of manufacturing and trade inventories to sales, commercial and industrial loans, the ratio of consumer installment credit to personal income rate, and the consumer price index for services. Traders and analysts pay attention to the indices to determine whether the U.S. economy is doing well or is slowing down. See also leading indicators.
