Abstract

<h4>Background</h4>Aggregation of spatial data is intended to protect privacy, but some effects of aggregation on spatial methods have not yet been quantified.<h4>Methods</h4>We generated 3,000 spatial data sets and evaluated power of detection at 12 different levels of aggregation using the spatial scan statistic implemented in SaTScan v6.0.<h4>Results</h4>Power to detect clusters decreased from nearly 100% when using exact locations to roughly 40% at the coarsest level of spatial resolution.<h4>Conclusion</h4>Aggregation has the potential for obfuscation.
