  Abstract: We consider the problem of counting the population size in the population model. In this model, we are given a distributed system of $n$ identical agents which interact in pairs with the goal to solve a common task. In each time step, the two interacting agents are selected uniformly at random. In this paper, we consider so-called uniform protocols, where the actions of two agents upon an interaction may not depend on the population size $n$. We present two population protocols to count the size of the population: protocol Approximate, which computes with high probability either $\lfloor\log n\rfloor$ or $\lceil\log n\rceil$, and protocol CountExact, which computes the exact population size in optimal $\operatorname{O}({n\log{n}})$ interactions, using $\tilde{\operatorname{O}}({n})$ states. Both protocols can also be converted to stable protocols that give a correct result with probability $1$ by using an additional multiplicative factor of $\operatorname{O}({\log{n}})$ states.
