Principles for Updating Data and Sources of Information
- The data included in the system is taken from reports of
county (powiats)heads (starostas) and presidents of
cities/towns classified as separate counties and our own
calculations based on the Central Statistical Office data
repositories
- The data refers to half-years periods, starting from 2
half of 2005, and is updated twice a year.
