German Birth Rate Continues to Climb（dw-world）
Von der Leyen said the reason behind the continuing rise in birth rates was a change in mentality.
"Young people have the feeling that the society will not simply leave them behind as parents," she said.
Von der Leyen, herself a mother of seven, introduced a parental leave reform in 2007 which included new benefits for German fathers allowing them to stay at home for a time with their children. The minister said her goal had been to lower the hurdles couples felt about having children.
According to surveys, 56 percent of stay-at-home mothers would like to work.
"But not at any price," said von der Leyen. "They want good child care and part-time work. We have to meet these mothers halfway."
２００７年に上昇に転じたが、その傾向が続いている。
理由は、子供を育てやすい環境の整備にあるらしい。
２００７年に父親にも産休を認めた、という。
