In Germany, the average number of children per woman in 2007 was 1.37, following 1.33 in 2006. Hence, in 2007 it rose for the first time since 2004. Last time the average number of children per woman was higher was in 2000 (1.38). In 2007 about 685,000 children were born, which was by some 12,000 more than in 2006. In 2008 the number of births was roughly the same as in 2007, according to the results available so far.
Population projections show how the number of the population and the age structure may change under certain assumptions regarding the development of essential demographic factors – the birth rate, mortality and migration.
