ESRC NCRMEvaluating and improving small area estimation methods

This network, funded by the ESRC's National Centre for Research Methods (NCRM) Programme, brings together experts in small area estimation (SAE) techniques from the academic and policy (eg Office for National Statistics, Teasgasc) communities in the UK and internationally in order to seek innovative ways to advance knowledge and understanding in SAE methodologies.

Context to the network

SAE methodologies have become a widely used method across various disciplines as a result of growing demand by policy makers and researchers for spatially detailed information alongside advances in small area data availability and computing power (Clarke, 1996). Various small area estimation methods have emerged and these can broadly be disaggregated into statistical regression-based approaches and spatial microsimulation approaches. Although less widely used in this context, agent-based modeling may also hold benefits for SAE.

Currently, despite the potential of these approaches and the growing demands placed upon them, there is little agreement within the academic and policy community as to which method(s) work best, whether different approaches are best suited to different local contexts, how best methods can be implemented and how best results can be validated. Experts from across each of these methodological strands and across a range of academic disciplines are included in the network so as to enable not only improvements in each separate approach but also overall methodological progress through the cross-pollination of ideas and skills.

The network has five core aims:

  1. To evaluate the performance of alternative methods across different small area contexts and to define general rules of guidance as to when specific methods seem to work most effectively and why
  2. To enhance the performance of the separate methodologies themselves
  3. To explore whether general rules of validation can be described
  4. To explore methods to ‘roll forwards’ small area covariate (eg census) data in light of anticipated changes to the UK census after 2011
  5. To disseminate findings and methodological skills widely
