This is the Index of Place Names (IPN) in Great Britain as at December 2015 (revised version, published July 2016). The IPN was first produced after the 1831 Census; this new version has been greatly expanded in content and extent. Featuring over 87,000 entries, it lists the names of localities and geography areas throughout England, Scotland and Wales. New geographies added are historic counties, lieutenancy counties, and police force areas. New features include code fields for place names, a separate indicator field to show where places are split across geographic areas, the streamlining of the previous local authority district fields into one field, and the expansion of Welsh language names. Latitude and longitude have also been added to bring the product in line with other ONS Geography products. The IPN is published annually and with an updated and informative user guide giving a full rundown and explanation of the contents (File Size 33MB).
