This paper analyzes the spatial clustering of galaxies in the Canada- France Redshift Survey (CFRS). We have used the projected two-point correlation function, w (rₚ_), to investigate the spatial distribution of the 591 galaxies with secure redshifts between 0 = 0. 5, although at lower redshifts, 0. 2 <= z <= 0. 5, blue galaxies are somewhat less strongly correlated than the redder galaxies, as seen in local samples. This effect could be the equivalent for field galaxies to the Butcher-Oemler effect seen in clusters of galaxies. The cross- correlation functions between red and blue samples have comparable amplitudes to the autocorrelation functions of each. The distribution and power spectrum of pair separations does not indicate significant periodic patterns in the distribution of galaxies along the lines of sight. Finally, the densest structures in the survey are identified and characterized, including the structure at z = 0. 985 in the 1415 + 52 field, reported previously, and a new cluster of galaxies at z = 0. 78 in the 1000+25 field.
