How can Government harness new data to improve policies?

6 July 2023

The Public Administration and Constitutional Affairs Committee today launches a new inquiry into the collection and analysis of data by Government and public bodies, and opportunities for reform of the current system.

More data are available than ever before, from supermarket loyalty cards to smart watches. MPs will examine how civil servants make the most of the mass of data generated to evidence decisions and achieve policy aims. 

Last month the UK's National Statistician suggested that modern data collection could make the 10-yearly UK census obsolete. In this inquiry, MPs will investigate the Office for National Statistics’ (ONS) proposals on the future of population statistics and examine whether statisticians could make better use of emerging data sources. 

MPs are also calling for evidence on using data ethically, the processes in place to protect the privacy of UK citizens, and issues with access to official statistics. 

Chair's comment

William Wragg MP, Chair of PACAC, said: 

“The data landscape, both inside and outside government, has changed dramatically in recent years, with sources multiplying exponentially. In this data deluge, how can Governments make sense of the numbers and improve the lives of the general public? The inquiry we’re launching today will question how statisticians and analysts can draw meaningful conclusions for Government from the mass of data we generate every day.  

“There are already a range of innovative projects underway across Government, ranging from the use of shipping data to enhance evidence on trade flows, to the potential of anonymised and aggregated phone data to improve travel statistics.  

“We will explore both the opportunities and the dangers presented by new data sources, questioning how demands for evidence are changing, what it means to use data ethically, and whether existing privacy protections are sufficient.”
