Although variability is a common property of newly formed stars, so far the full breadth of periodic and aperiodic variability in young stars has not been studied in quantitative detail. We are using the Palomar Transient Factory (PTF) to carry out a multi-season survey of the North America Nebula complex. In addition to improving the membership list for this poorly-studied star forming region, our survey will provide a systematic look at both periodic and aperiodic variability in young stars. Aperiodic variables are a relatively unexplored area of young star research compared to periodic variables, whose easily quantifiable periods make them relatively simple to analyze. By addressing both kinds of variability we will obtain a clearer picture of the diverse processes that affect stars in their early evolution. We present preliminary work toward characterizing the variables in our sample.
