We report the correlation analysis of various
redshift surveys which shows that the available data are consistent
with each other and manifest fractal correlations (with dimension 
) up to the present observational limits (
)
without any tendency towards homogenization. This result points to a
new interpretation of the number counts that represents the main
subject of this letter. We show that an analysis of the small-scale
fluctuations allows us to reconcile the correlation analysis and the
number counts in a new perspective which has a number of important
implications.
