In January of each year, the Federal Reserve Bank of Philadelphia revises historical data for the Business Outlook Survey after calculating new seasonal adjustment factors. Because survey responses exhibit seasonal patterns, new seasonal factors are calculated each year based on the addition of a complete year of data. While this year's revisions affected levels of the indexes for certain months, the pattern of change in most series was not significantly affected.
Revised historical data for all series can be retrieved from the historical data page: http://www.philadelphiafed.org/econ/bos/boshistory.html
The data are also available upon request by calling (215) 574-4119 or by e-mailing Katherine.Woodbury@phil.frb.org.
The next scheduled release for the Business Outlook Survey is Thursday, January 17, 2002.
