🆕Known limitations

There are some agreed and known challenges with capturing and publishing data for Building Age, Construction Material and Basement Presence.

• There is no single, definitive measurement or information available for any of these attributes at a national scale.

• There are limited and sometimes conflicting sources of information from which to derive values.

• The real world can be very difficult to represent in data. For example, new builds can be made to look like older buildings.
