Reasons for negative population growth in Germany

The birth rate is lower than the death rate. Germans prefer quiet to children. For example, when they rent a house, the landlord rarely rents it to families with children, but prefers to rent it to families without children. Nowadays, young couples in Germany enjoy it when they are young, but they can't afford it. When they are old, they have no children or daughters. More and more Germans go to other countries, such as America.
