First, classify before drawing conclusions about identity document verification; age is not the determining factor as often thought.
There are two main categories influencing this behavior: situational factors and personal behavioral factors.
An unexpected business trip, or a specific visa requirement, is a situational factor that can force anyone to act at the last minute, regardless of age.
Procrastination or travel experience are more relevant personal behavioral factors than age; for example, a seasoned senior traveler may be complacent, while an inexperienced young person will be very organized.

Two categories here: age segmentation for marketing and document management for practical security, and mixing them is a fundamental mistake.
The behavior of verifying documents depends on risk awareness and concrete experience, not broad demographic generalizations.
Someone who has missed a flight in Frankfurt due to an expired passport will develop a rigorous discipline, regardless of their age.
It is preventing concrete troubles, like delays at customs or boarding refusals, that motivates anticipation, not vague “travel stress”.
In Germany, rules are rules, and respecting administrative formalities is a matter of common sense and individual responsibility.

There are two distinct categories here: travel planning and identity document verification.
Segmentation by age is relevant for understanding travel expectations, but not for document verification behavior.
It is administrative complexity and the consequences of forgetting that determine how and when people verify their documents, regardless of their age.
For example, in Germany, the need to have a valid identity document for simple procedures encourages everyone to anticipate, not just a certain age group.

Let's classify first, then judge: there is marketing segmentation and actual behavior.
Age segmentation is a useful category for targeting offers, but it does not directly dictate whether someone verifies their documents in advance.
A young person traveling for the first time will probably be very organized, regardless of age, while an experienced business traveler may delegate or ignore until the last minute, depending on their habits.
What really matters is individual experience and personal constraints, not the abstract age group.
In Berlin, even a student can be hyper-rigorous with their documents if an international trip depends on a complex visa.

Let's strip away the media hype about age segments: the actual behavior of document verification has nothing to do with abstract demographic categories.
What matters are the practical consequences: missing a flight at Zaventem or being blocked at the French customs, that makes you move.
A Belgian who has already had a expired passport will not see their way of verifying papers change with age, but with the concrete fear of trouble.
The actual cash flow does not change with a nice age infographic; it is the administrative rules and loss of time/money that drive action.
