What could be the source for this "information" in the map? Original research? There is no constitution or law of any country as far as I know that says the "country" "believes in astrology" of any variant. A number of countries' constitutions do speak of an "official religion", most of which religions prohibit belief in astrology.
For example, astrology is prohibited in Saudi Arabia because it officially has Islam for an official religion, so what do you mean by the "country believes in astrology"? Til Eulenspiegel (talk) 14:24, 30 ጁላይ 2016 (UTC)
