Problem of weights in the analysis of demographic phenomena in territorial arrangement.

The author attempts to eliminate the influence of the size of a territorial unit on the results of demographic analysis, using data for Poland as an illustration. She concludes that "the inclusion of weights in statistical analysis allows us to eliminate the impact of the sizes of studied units on the values of counted parameters as well as on the measures of correlation and regression. The existence of a close connection between the results obtained and the sizes of the studied groups within the same population should be always taken into account."
