The API Weekly Statistical Bulletin is usually published each Tuesday and covers the previous week's activity. A separate Monthly Statistical Report, which is published two to three weeks following the end of the report month, analyzes and comments on the significance of trends reflected in the weekly data. Prior years' data are available at a reduced price.
Customized reports are also available for specific weekly series at a negotiable cost.
