Abstract
The distributions of the numbers of Lyα systems with respect to redshift, HI column density and Doppler parameter are examined. While a number of the suggested features may be due to selection effects, it is likely that there is some redshift dependence in the distributions of the other two parameters. At high redshifts there may be a population of relatively shortlived clouds, while those seen at lower redshifts could be a longer-lived component which is often associated with galaxies. The prospects for testing models using line profiles are discussed.
