Survey contact rates differ across countries. However, to date the reasons for these cross-country differences have not been identified. Differences can be due to differences in survey characteristics, differences in population characteristics and differences in processes, i.e. in the association between the first and second reasons and contact propensity. The paper investigates correlates of contact by decomposing cross-country differences in predicted mean contact propensities into these three components. The findings explain which fieldwork strategies and population characteristics are related to cross-country differences in contact rates. The analyses distinguish factors explaining within-country contact propensity from factors explaining cross-country differences. We demonstrate the suitability of decomposition methods for analysing group differences in survey outcomes.
