In general, the paper deals with population forecasting. Selected extrapolation methods are used for the case of NUTS III regions in Slovakia. The main aim is to verify how reliable they can be with respect to the recent demographic and socio economic processes in Slovakia after 1989 within transformation. We have presupposed the linkages among the demographical and socio-economical changes and curves; therefore, we have attempted to verify how fluctuation, rapid changes during last decade, and reduction of these fluctuations influence the accuracy of the models. There seems to be a strong linkage between the demographic and socio-economic systems. Stability of the demographic one is higher although influenced by fluctuations of the economical ones. There is no doubt that the rapid demographic change will influence features such as retirement system in the future. It is necessary to know how populous and old will be the Slovak population and sub-national ones. The more accurate will be the results, the more suitable will be for the economists and planners.

Wittgenstein describes the process of mastering a rule (adopting a skill) as implanting mechanically a number of specific examples (steps) after which one “know how to go on”. Such a two-step concept of learning (e.g. in Cavell) can be understood as the sequence of i) propedeutics limited in time and ii) the subsequent skill to extrapolate the rule in unlimited number of cases (Chomsky’s account of rule). The relationship between the “propedeutics of examples” and the mastered skill is, however, more complex. The author will refer here to the Wittgensteinian ethics (e.g., Winch) emphasizing the individual’s repeated work (reflection) on specific examples which never ends. He will also point to the empirical evidence (Ingold, in particular) that in the processes of learning an essential role is played by memorizing and copying of given (specific) models, where attention and observation is necessary. A competence is then a physical implantation and individual mastering of such a limited technique, rather than an ability to extrapolate and innovate foremost.
