The analysis refers to the author earlier publication and shows regional differences between the population size by the census 2002 and estimated on current registration, subjected to both overestimation and underestimation. Here these differences are related to missing responses. In certain 'gminy' (communes) the share of missing answer comes over 20 per cent (average in Poland - about 2 per cent). A non-response is analysed with respect to the place of residence, education and source of maintenance of a respondent. Results confirm the previous conclusions that the regional differences between the census population size and the population estimated on current registration result from unregistered emigration, especially oscillatory one.
