Summary/Abstract: There are two aims in the article; firstly, to present the theoretical assumptions and the calculation techniques used in inverse projection. The method, widely known in the Anglo-Saxon literature, created in the 1970s by Ronald D. Lee and developed by members of the so-called Cambridge Group has not been yet comprehensively discussed or applied by Polish demographers. The second aim is practical and consists in carrying out simulations confirming the flexibility while choosing the initial parameters of the models of populations that are being constructed.
