The distances to the sources of Gamma-ray Bursts (GRBs) are not known. There have been many attempts to obtain information about the spatial distribution of GRBs from their source count data, the so-called LogN-LogS relation, and angular distribution data. As is well known, the new results from the BATSE instrument on board the Compton Observatory (GRO) have greatly magnified the difficulty with the galactic neutron star model of GRBs. It is, therefore, important that the analysis of the data is carried out properly. This task, however, is not straightforward because the selection criteria of GRBs are not simple and the triggering threshold varies with time and instrument. Consequently, the analysis of the LogN-LogS data and the interpretation of the results have had a checkered history. The past procedures will be reviewed and their shortcomings and possibilities of obtaining misleading results will be discussed. A new and statistically correct method, that takes proper account of the variable nature of the triggering threshold and is well suited for analysis of GRB data will be described. Results from application of this method to old and new GRB data will be presented. How these results differ from old results and what bearing they have on the interpretation of the GRB data will be discussed. This work is supported by NASA grant NAGW 2290.
