Common sources of data include household and living standard surveys, sectoral statistics, labour force reviews and so on. Experience to date, however, has shown that data collection processes often differ and there is a lack of alignment between global monitoring needs and national reporting capacities (Paris21, 2013). The approach used by the UK for the 2012 national assessment of flood risk was to score datasets against a number of criteria to determine their statistical quality and relative strengths and weaknesses (see Box 2.1). However, such scorecard assessments can be difficult to do in practice if there is no central data repository or if there is limited co-ordination between data producers and users.
