Limits. These are the figures as the Bureau of Labor Statistics published them and FRED carries them today; later revisions can change them. The brief makes no forecast and does not compare the release with economists' expectations.
Method and source. Octans Research reads the series from FRED on release day. Published levels and rates are used as they are; changes are computed from the published levels, and "highest since" compares the latest reading with the full history of the series. The text is generated by a fixed template; no model wrote it.
