Average age of the population in Germany
Average age of the population in Germany stood at 45 years in 2025, according to Federal Statistical Office of Germany (Destatis). It is one of the indicators in the Population and demographic structure table (Value · Annual), with a complete series running from 1990 to 2025.

Understanding average age of the population in Germany
Central tendency of the country's demographic distribution is summarized by this indicator, which computes the arithmetic mean age across all registered inhabitants at year-end. Unlike tables that group the population into predefined age bands, this single metric aggregates every individual resident from newborn infants to the oldest centenarians into an unweighted arithmetic average. It incorporates every person registered with primary domestic residence, reflecting the combined structural impact of historical births, longevity improvements, and cross-border migration patterns.
Because this metric is an arithmetic mean, it responds to shifts across every cohort rather than dividing the population in half like a median. Expanding senior cohorts pull the average upward, whereas newborn arrivals and inflows of young adult migrants exert downward pressure. A common error when reading this figure is assuming that an upward movement implies uniform aging across all regions or subgroups; localized age profiles vary considerably, and large influxes of working-age adults can temporarily stabilize the national average. When benchmark censuses recalibrate population registers, minor revisions to cohort tallies can adjust the calculated mean without reflecting genuine biological shifts.
Frequently asked questions
- How does the average age differ from the median age of the population?
- The average age is the arithmetic mean across all inhabitants, whereas the median marks the middle point where half the population is younger and half is older.
- Are centenarians and very old individuals excluded from this calculation?
- No, every resident is included up to the highest recorded ages, with their full completed years factored into the mathematical mean.
- How does international migration affect the population's average age?
- When cross-border arrivals are concentrated among young adults and children, their presence exerts a downward mathematical pull on the national average age.
