The average age for women to become mothers no longer increases. In 2006, women were on average 31.1 years old when their child was born. First-time mothers averaged 29.4 years in age, the same as in 2004 and 2005.
In 1970, first-time mothers were on average somewhat over the age of 24. Until the mid-1990s, the average age increased rapidly, because many women postponed motherhood. Women attended school longer, their participation in higher education increased and more women entered employment. In the past decade, the age of first-time mothers continued to increase. The postponement process appears to have ended two years ago.
