Bremen is a city-state with a very high percentage of immigrants (with low IQ), the highest degree of unemployment of a state of former West Germany and the most desolate school system of any Germany Bundesstaat (socialdemocrats are governing this state since decades). What is cause and what is consequence, is an open question. But there are reasons enough, why the scores are such low ones. Bremen is the Louisiana of Germany. Within Germany income, rate of unemployment and GDP are highly correlated with mean regional IQ. Economically, Baden-Würtemberg and Bavaria are on the top, Bremen on the bottom.
