You asked

Please could you provide shapefiles (or other form of boundary data) for electoral wards in England and Wales for the years 1970, 1980, 1990, 2000, and 2010 (or intermediate years should these years not be available).

We said

Thank you for your enquiry.

We only support administrative boundaries in use since 2011. You can download Ward boundaries for all years back to 2011 from our Open Data Portal.

Ward boundaries for the Census years 1971, 1981, 1991, 2001 and 2011 can be downloaded in a variety of formats from the UK Data Service.

(Note that older boundaries (including 1971) are available by using the Boundary Data Selector tab.)
