In general, the term demographic change refers to an increasingly established departure from demographic models which had been common earlier. The change in German demographic structure is also noticeable because of the prevalence of older age groups. As the 21st century proceeds into full-fledged adulthood after its 21st birthday, forecasts predict population numbers in Germany will continue to fall in the following decades.
A common example is the growing number of one person households in Germany, and the same can be said for two person households. Meanwhile, larger household numbers have been decreasing. Though it doesn't necessarily follow that every household with more than two members included children, this is still a pattern that can also be connected to changes in family planning among the population.
Most German families with children had one child. Compared to other European countries, Germany actually still recorded some of the highest number of marriages in 2019. On average, people tended to get married in their early to mid-thirties.
The birth rate in Germany has generally been falling for a long time, though occasional increases have also been recorded. As of 2020, there were 773,166 births. Based on the most recent data, approximately 1.54 children were born per woman. More deaths than births occurred in the country annually since 2000.
