The size distribution of land plots is a result of land allocation
processes in the past. In the absence of regulation this is a
Markov process leading an equilibrium described by a probabilistic
equation used commonly in the insurance and financial mathematics.
We support this claim by analyzing the distribution of two plot
types, garden and build-up areas, in the Czech Land Registry
pointing out the coincidence with the distribution of prime number
factors described by Dickman function in the first case.
