Replication data for: Estimating Constituency Preferences from Sparse Survey Data Using Auxiliary Geographic Information

Yet, such measures are often difficult to obtain. Previous survey-based estimates frequently lack precision and coverage due to small samples, rely on questionable assumptions, or require detailed auxiliary information about the constituencies' population characteristics.

We propose an alternative Bayesian hierarchical approach that exploits minimal geographic information readily available from digitalized constituency maps. If at hand, social background data is easily integrated. To validate the method, we use national polls and district-level results from the 2009 German Bundestag election, an empirical case for which detailed structural information is missing.
