The Business Cycle Indicators - U.S. Indicators database provides economic indicators that have proven to be most useful in determining current conditions and predicting the future direction of the United States economy. A common spreadsheet-type format is used, allowing the BCI series to be easily imported into numerous software programs (including EXCEL, LOTUS-123, FREELANCE, EVIEWS, TSP, and SAS). More than 250 economic series are in the U.S. BCI dataset, with many series beginning in 1945.
