The Office for National Statistics (ONS) has used a register based on Ordnance Survey’s AddressBase Premium product to ensure every household in England and Wales received instructions to access the questionnaire for the National Census.

It will also be used by census officers to visit and help households that have not completed the questionnaire.

This follows a three-year work programme by Ordnance Survey, GeoPlace and local authorities to ensure AddressBase Premium is as up to date as possible, particularly on the data associated with communal establishments, tertiary level residential classifications and student hall accommodation. This reflects the fact that the census also applies to managed accommodation.

GeoPlace said that over the three years there has been a 29% improvement in residential records being classified to a tertiary level to just over 97%.

Due to their statutory roles around planning and street naming and numbering, local authorities are the originators of addresses and property change intelligence. GeoPlace manages a central national hub, taking feeds from every local authority in England and Wales to develop a consistent national dataset.
