(Polish title: Budowa modeli eksploracji danych (data mining) na potrzeby analiz cech charakteryzujacych osoby bezrobotne i przewidywania pozostania osoba bezrobotna). The article discusses data mining models that can be useful in the analysis of attributes influencing individual unemployment and can help to estimate the probability with which persons with certain characteristics (age, education, gender, family background, family status, family size etc.) are more likely to be unemployed or to lose their job. Three models were constructed, and verified, to accomplish this task: logistic regression, multilayered neural network and decision tree. The study was based on Polish official statistical data. SAS Enterprise Miner software from SAS Institute Inc. was applied for model construction and data analysis.
