The distribution of young stellar objects (YSOs) toward the Cygnus X region obtained from the Infrared Astronomical Satellite (IRAS) is combined with a recent (C-12)O (J = 2-1) survey. The most luminous YSOs are examined for membership in the Local arm and the Perseus arm. The far-infrared, radio, and molecular emission is also analyzed from a global perspective. Seventy YSOs have been identified, corresponding to stars earlier than about B7 ZAMS, primarily associated with molecular clouds in the Local arm. The (C-12)O (J = 2-1) emission associated with these YSOs reveals 23 instances of broad-line wings including 10 with spatially complex, extended high-velocity molecular emission. We have identified a new Perseus arm star-forming region, IRAS 20144+3726, and have also identified 20264+4042 and 20321+4112 near the H II regions DR 7 and 18P61 as broad-wing outflow sources also located in the Perseus arm. We conclude that no more than three YSOs earlier than approximately B0 ZAMS currently exist in the Perseus arm region located behind Cygnus X.
