Interesting. The relatively high number in India compared to surrounding locations says to me that there is a strong component of culture (determines if things are recorded) and population density. On the other hand, flyover country in the US seems to get more than the coasts, despite population density, so perhaps light pollution on the coasts is skewing the results?
