ASTRONOMY-RELATED ORGANIZATIONS OVER THE WORLD

The geographical distribution of astronomy related organizations is il lustrated from comprehensive and up-to-date samples. Results for profe ssional institutions, for public observatories, for planetariums, and for associations are commented and compared to an earlier study involv ing only observational locations (observing and receiving stations). S pecific distributions of astronomy-related publishers and software pro ducers are also illustrated. There is a reinforcement of the tendencie s pointed out in the previous study with very high densities in Europe and Northeastern U.S.A. Comments are offered on specific concentratio ns and national differences. It is also clear that numerous institutio ns and associations are not involved in direct observing. The astronom y-related publishers and software producers are interestingly concentr ated in only a few places.
