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 ( r _ { p } ) , to investigate the spatial distribution of the 591 galaxies with secure redshifts between 0 \leq z \leq 1.3 in the five CFRS fields .
The slope of the two-point correlation function for the sample as a whole is \gamma = 1.64 \pm 0.05 , very similar to the local slope , and \gamma is therefore not strongly evolving with redshift .
However , the amplitude of the correlation function decreases strongly with increasing redshift , so that at z \approx 0.6 it is a factor of 10 lower ( for q _ { 0 } = 0.5 ) than for a similarly-selected local galaxy population , on scales 0.1 < r < 2 h ^ { -1 } Mpc ( q _ { 0 } = 0.5 ) .
As a whole , the CFRS data is adequately represented by r _ { 0 } ( z = 0.53 ) = 1.33 \pm 0.09 h ^ { -1 } Mpc for q _ { 0 } = 0.5 , and r _ { 0 } ( z = 0.53 ) = 1.57 \pm 0.09 h ^ { -1 } Mpc for q _ { 0 } = 0 .

Unless the galaxy population at high redshift is quite different from any population seen locally , an unlikely possibility , then this implies growth of clustering as described by the evolutionary parameter \epsilon to be between 0 < \epsilon < +2 .

No difference in the clustering of red and blue galaxies is seen at z \geq 0.5 , although at lower redshifts , 0.2 \leq z \leq 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 auto-correlation 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 .
