ONS Full History of a UK Time Series (Monthly, Quarterly and Annual Figures)
ons/time-series-history
Every published figure of one Office for National Statistics time series since it began, as monthly, quarterly and annual lists, oldest first (UK CPI and CPIH inflation back to 1989, unemployment and employment rates back to 1971, GDP, public finances and more), with the series title, unit, release date and the list of its earlier releases. A series is published at one or more frequencies and the other lists are empty. Values are strings; an empty string means no figure for that period, not zero, and can fall at the start, in gaps, or at the very end of a list. For labour-market three-month averages the row date names the window's middle month and label gives the window (date 2026 JUN, label 2026 MAY-JUL). The response is the whole series, up to about 180 KB, with no date filter. Find the series' uri with ONS Time Series Finder; for just the newest figure use ONS Latest Figure for a Time Series.
