The word is composed of 'Durchschnitt' (average) and 'Alter' (age). The 's' in the middle is a linking element that connects the two words. Literally, then, it is the 'age on average.'
Man kann das Durchschnittsalter einer Gruppe leicht berechnen.

To state the value, fixed formulations are used, such as 'Das Durchschnittsalter liegt bei … Jahren' (The average age is around/at … years) or 'Das Durchschnittsalter beträgt … Jahre' (The average age is … years).
Das Durchschnittsalter der Teilnehmer beträgt 35 Jahre.

The group that the average age refers to is usually indicated with the genitive or with the preposition 'von' (of/from).

life expectancy
'die Lebenserwartung' and 'das Durchschnittsalter' both have to do with age and statistics, but they mean different things. 'Lebenserwartung' says how long a person or group is expected to continue living, or how long they can live in total. 'Durchschnittsalter' says how old the people in a group are on average right now. The words are easy to confuse because both often appear in texts about population, health, or countries. The important point is the direction in time: 'Lebenserwartung' looks forward to the expected length of life. 'Durchschnittsalter' describes the current age of a group.
