In some regions the number of women between the ages of 20 and 30 has dropped by more than 30 percent.[1] In 2004, in the age group 18-29 (statistically important for starting families) there were only 90 women for every 100 men in the new federal states (including Berlin).[91] In parts of the state of Thuringia, there are 82 women for every 100 men.[88] The town of Königstein has the biggest demographic imbalance in Europe between young men and women.[88] This is in contrast to many areas in Europe as many cities across the continent suffer an imbalance of younger women to men.[92] This has led to the concern to local leaders, as a large imbalance of males to females is usually linked to historical social instabilities and increased crime rates.[88]
