Definition, coverage & attribution
CPI-U, U.S. city average, monthly regular publication, not seasonally adjusted. SA0 identifies all items; SA0L1E excludes food and energy. The index base is 1982-84=100. These are publisher index levels, not native YoY inflation rates. The standard BLS index history is retained as published. Changing expenditure weights and historical methods are not homogenized into a constant-method research series. Publisher monthly index reference period; individual sampling or quotation dates are not exposed by this API. Exact source reference date unknown; calendar month end is a SOTW coverage/freshness boundary. Original numbers, explicit missing rows and footnotes retained. No growth rates, payroll changes or release times are computed. Absent preliminary flags do not establish finality.
