The indicator is defined as the ratio between male and female population aged 25 to 39. Due to lack of data, the average ratio in time period 2007-2011 has been calculated.
Ideally, there should be a balance between male and female population in a region; great imbalances hint at social problems, and are obstacles for further social, demographic and economic developments.
The map depicts regional gender imbalance in the age bracket of 25-34 years where the total national population of any country is usually close to the gender balance, but at the same time people are very mobile. In BSR as a whole, there is a trend that young women are more than men biased to migrate to urban centres or abroad. In every country, regions with deficit of women largely prevail. The higher levels of overrepresentation of women can be observed in the Baltic States, Germany and Denmark. In Germany and Denmark women favour the cities of Copenhagen, Hamburg and Bremen or their adjacent areas. In the Baltic States, the metropolitan areas of Riga, Vilnius, Kaunas and Tartu are most attractive for them. The worst deficit of women can be met in East Germany, northern Finland and Sweden.
