A sequence (an)n≥0 is k-automatic if there is a finite automaton that, on input n expressed in base k, reaches a state with output an. In this paper I will survey some recent advances concerning enumeration of various aspects of these sequences, such as the recurrence function, and the subword complexity (which counts the number of distinct blocks of length n).
