The Institute for Social and Economic Research (ISER) at the University of Essex is home to a world-class team of survey and research experts who specialise in the production and analysis of longitudinal data – evidence which tracks changes in the lives of the same people over time.

ISER enjoys an international profile for its cutting-edge socio-economic research, which is used by academics and researchers, policy makers, other influential bodies, charitable organisations and journalists involved in ongoing debates about society. It is also one of the leading centres in the world for research into how surveys are carried out.

The ISER podcast series showcases some of ISER's research in easy-to-listen-to 5-6 minute interviews, in which researchers talk about the background to their work, how they got their information, their key findings and what they mean.
