The structure of the universe as viewed from the distribution of galaxies at scales ranging from 1/h Mpc up to about 20/H Mpc is discussed on the basis of recent Southern Sky Redshift Survey data. In addition to the two-body correlation function, the J3 integral and galaxy counts in clustered regimes that describe the clustering especially in the dense parts, attention is given to the statistical indicators that best describe the underdense regions: statistics of voids and counts in cells. The typical size of voids and its dependence on the galaxy density are determined. Samples of various depths are used to examine the variations of these statistical indicators. The density decrease for the deeper samples is found to be solely due to the variations of the galaxy diameter limit; all indicators, when corrected for their obvious density dependence, show only quite small variations. A density-dependent but depth-independent limit is found for the size of the voids that for a sample with 0.01/h cu Mpc galaxies have a diameter smaller than 20/h Mpc at the 99-percent confidence limit.
