Tracking biases : an update to the validity and reliability of alcohol retail sales data for estimating population consumption in Scotland
MetadataShow full item record
Aims: To highlight the importance of monitoring biases when using retail sales data to estimate population alcohol consumption. Methods: Previously, we identified and where possible quantified sources of bias that may lead to under- or overestimation of alcohol consumption in Scotland. Here, we update findings by using more recent data and by quantifying emergent biases. Results: Underestimation resulting from the net effect of biases on population consumption in Scotland increased from -4% in 2010 to -7% in 2013. Conclusion: Biases that might impact on the validity and reliability of sales data when estimating population consumption should be routinely monitored and updated.
