Editing Economic indicator (section)

=== 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.<ref>Smith, Charles Emrys, "Economic Indicators", in Wankel, C. (ed.)
