This is a collaborative programme of research work on big data and data science with ONS. A cross faculty work between ECS and S3RI researchers to work with ONS statisticians. Our role is to bring in state of the art big data technologies and fundamental concept of data science for adding value to ONS survey data. These are put in context of specific applications that will enhance surveys methods. Extraction of knowledge from big data gives an edge over traditional methods of surveying by bringing added value and efficiency to operations in surveys.
