This CSV file provides data, at LSOA level, for Cambridgeshire, West Suffolk and Peterbrough, grouping homes into four categories of date when they were built:
•Built before 1929
•Built 1930 to 1939
•Built 1945 to 2015
•Unknown built date

It is based on data released by VOA, using Council Tax records. When trying to identify homes with solid walls, data of construction is very useful as homes built before 1930 tend to all have soild walls, from 1930 to after the second workld war they then to be mixed, and since 1945 cavity wall construcitno was the most common.

Local naming has been added to clarify the geographies covered by each LSOA. Further detail will be posted on how these local geographies have been identified shortly.

This csv file was amended in May 2016 to remove some minor coding errors. The data remains exactly the same as in previous versions.
