Linking data allows researchers to analyse information collected by other organisations together with Understanding Society information. These organisations include government agencies, such as the NHS, DVLA or education records, other data-holders, such as the Financial Conduct Authority (FCA) or social networking sites. Data can only be linked if Understanding Society participants give their informed consent.
The information from the different organisations which can be linked to Understanding Society includes information about education, health, transport and economic circumstances. While the research potential is exciting, the processes and procedures for making linkage possible are detailed and complex, requiring carefully sought permissions from participants and the co-operation of external organisations who own the administrative datasets.
