A study of the luminosity and spatial distributions of a deep, complete sample of emission-line galaxies (ELGs) is presented. The luminosity function (LF) is found to be flatter than that of normal galaxies at low luminosities, and the integrated LFs show that ELGs contribute 6.7 + or - 2.0 percent to the overall galaxy LF. Space densities of the various types of ELGs found in the survey are also derived. The ELGs are found to follow for the most part the structures defined by the luminous galaxies in the Catalog of Galaxies and Clusters of Galaxies. However, the ELGs strongly avoid regions of very high galactic density and a number of low-luminosity ELGs reside in regions otherwise devoid of normal galaxies. The overall density environments within which the ELGs are found are significantly lower than those of the normal galaxies. 82 refs.
