A place for panel data in the 'data revolution'?

This briefing Introduce the concept of panel data and explains how it differs from other types of survey. It discusses the strengths of panel data and considerations when implementing and analysing a panel survey. And provides examples of how existing panel surveys have been able to influence and improve policy and practice. The brief recommends the implementation of nationally-representative panel data to provide a benchmark for measuring progress towards the post-2015 goals.
