We have conducted a high resolution infrared survey of a large sample of Class I protostars to determine their binary frequency distribution from 60 AU to 5000 AU. Our goal was to address the question: "Do stars form in isolation?". To do this, we compiled a new sample of 267 nearby candidate Class I objects from across the whole sky, and observed those visible from Mauna Kea at H, K, and L' with a median resolution of 0.34" at L'. Our survey found 90 companions to 207 targets. In addition to being consistent with previous studies showing a strong binary excess over the solar-type main-sequence population, we have also observed a binary excess at wider and closer separations than previous studies. Our research is the first to have observational evidence for dynamical evolution through changes in the binary frequency distribution within the Class I lifetime, as well as differences in the protostellar binary statistics between star forming regions. This research was funded by the NASA IRTF.
