Age Lines: How to Define “Adults” and “Youth”

Written by Sven Bonnichsen Apr 11, 2011

Youth Liberation seeks to change how adults treat young people. But what
makes someone an “adult”? Who falls into the category of “young people”?
Where is the line between these two groups?


Before we begin trying to answer these questions, it’s valuable to take a
step back and look first at the more general concept of age. It seems to me
that there are three main models of age:

1. Age as biology
2. Age as legal status
3. Age as personal character


The “age as biology” model addresses natural phenomena: the sheer number
of years that one has been alive, growing taller, physical changes associated
with puberty, dental record, brain development, etc. Several of these a
ttributes could be equated with “adulthood”: when one has lost all their “baby
teeth”, when one stops getting taller, when secondary sex characteristics such as
menstruation, breast development, and facial hair appear. However, it’s
important to notice that discussions about “adults” and “youth” seldom have
anything to do with biology itself — focus is almost always on social differences
(law and character).

[A noteworthy variant of the “age as biology” model is the concept of
“mental age”. The “mental age” model suggests that just as the body progresses
through stages of development, so does the mind — but development of the two
are not always in sync. This idea most frequently comes up when discussing
people with “developmental disabilities” — adults with the intelligence or
emotionality “of a child”. …The popular sentiment that “you’re only as old as
you feel” also invokes the “mental age” model.]


The “age as legal status” model addresses laws that sort people into the
categories “adult” and “minor” (or simply “under age”). While attempts may be
made to associate legal age-lines with natural biological changes, they are
in themselves entirely artificial. There is no meaningful difference between
an 18-year-old on their birthday, and the 17-year-old they were the day before,
except that which is invented and imposed by legislators.


The “age as personal character” model equates “adulthood” with behavior:
you’re an adult when you “act like an adult”. …What do you have to do to
act like an adult? There are a variety of ideas about what that entails — and
some conflict with each other.

Frequently adulthood is equated with “maturity” — a set of virtues that
everyone should aspire toward: being responsible, serious, hard-working,
intelligent, patient, wise, conscientious, competent, etc. When parents say “grow
up!” or “act your age”, they seem to be saying that maturity is accomplished
by effort and will. On the other hand, when adults say things like “you’ll
understand when you’re older” and “the wisdom of age”, it sounds more like
maturity can only be achieved by living long enough in the world — but if you can
just do that, then it’s inevitable. Other variants on the theme of “acting
like an adult” focus on the culture of adults (what they wear, what music they
listen to, what kind of language they use), or being in a position to supervise
(e.g. the oldest child getting to be “the adult” while their parent is away),
or the power of command (“because I’m the adult and you’re the kid, that’s

Ultimately, the promise that you can get treated like an adult, just by
acting differently, is hollow. Even if a 16-year-old is responsible enough to
be a store manager, intelligent enough to win national science awards, and /
or conscientious enough to start a community service organization, they still
don’t earn the right to vote.


Age laws are not entirely consistent. Different laws set different ages
as the dividing line between youth and adults: 16, 18, 21, 25, etc. We need
to look past the actual numbers and see the logic behind society’s structure.

Society is set up to imitate the generations within a family. In the
family, there are children, parents, and grandparents. In society at large,
there are minors, adults, and senior citizens.

From this perspective, young people are most defined by being living in
the home of their parents, and by being financially dependent. A few
exceptions should be noted. In addition to living situations with both biological
parents, living with a single parent, adoptive parents, or foster parents also
counts. Street youth are no less youth, because people generally feel that
they’re “supposed” to be with the parents. Youth who are financially independent
or legally emancipated also count, again being lumped in with their age-peers.

Of the various age-lines established by law, 18 seems to be the most
common and most significant. Most high school systems are set up so that students
will graduate when they are about 18 years old; most youth also leave their
parents’ home at about this age. If we had to pick a single age line to define
youth, it seems that 18 would probably be the best choice.

Most people, however, don’t feel that a person is fully adult upon
reaching age 18. Some legal entitlements are still withheld, and much of the social
stigma attached to youth remains in place. I’m going to argue that people
aged 18-25 constitute a meaningful sub-group of adults. Among activists that
I’ve worked with, “tweeners” is the word being used to discuss people in this

People who have just graduated high school and are going off to college
are often referred to as “college kids” — even though they they’re now treated
as “adults” by the judicial system. Why? I believe it’s largely because
these students are usually still dependent on their parents for money. They may
be living away from home, but the other half of what would make them “youth”
is still in place.

The ultimate confirmation of one’s adulthood is to marry and become a
parent oneself. According to a recent survey from the University of Chicago, the
average American feels that people should get married at age 25.7, have
children at age 26.2, and that adulthood begins at age 26 (
…It appears that society’s emphasis on attending college has socially (if
not legally) extended adolescence.

Perhaps the strongest case for seeing 18-25 as a meaningful grouping is
that this age group is required to register for the draft (selective service).
Whereas one must be 18 to vote (lowered from 21 in 1971), you must be a
minimum of 25 years old to become a state representative, 30 to become a senator,
and 35 to be become president. With the exception of these last two cases, 25
is the highest age-line that I am aware of. [You have to be 25 to rent a car
— a fact that once stranded me overnight in Pennsylvania!]

[Within Youth Liberation, questions about where to draw the line between
adults youth probably come up most often when deciding who may be members of
an organization. There’s general recognition that 19- and 20-year-olds still
suffer much of the stigma of youth — but still, they have more legal freedom
than 17-year-olds. Often activists’ solution is to set the cut-off for
membership at a compromise number, such as 23. To me, this is a bad solution. It’s
offensive that adults base young people’s freedom on artificial age lines;
it’s little better if youth themselves pull numbers out of a hat. I feel that if
you’re going to draw age-lines, then they should be in direct response to
legal realities. For these purposes, “youth” should be defined as “under 18”.
If you want to include “tweeners”, then set the cut-off at 25 — but set limits
on their participation, to help level the playing field for the actual minors
in the group.]


While it is possible to talk about age in terms of biology — infancy,
early childhood, puberty, adolescence, adulthood, etc. — anatomy and physiology
have relatively little to do with adults and youth relate with each other.
Infants are physically dependent on others for survival; as society is
currently structured, young children require assistance to procure food and clothing;
teens typically remain financially dependent. Super-imposed upon these real
needs, however, is adults’ belief that they should always have the right to
command and be obeyed.

Gerontocracy, rule by the elders of a society, has probably existed for
thousands of years. It’s intuitive for most people to feel that they’re better
persons because they’re older and more experienced. Adultism, however, is a
relatively recent development, coinciding with the emergence of organized
states. Now instead of whoever’s oldest having the most power, adults have
organized themselves into a government that wields power over both minors and senior

I find it extremely useful to think about “adults” as if it is an
organization. It’s more massive and less orderly than organizations we’re used to
thinking about, but the metaphor holds up remarkably well. An organization has
leaders; given that youth are excluded from running for office, “leaders” here
is synonymous with the U.S. government. An organization has members; these
are all the adults who passively enjoy rights conferred upon them by the
government. [As the advertisement for American Express credit card used to say,
“membership has its privileges”.] An organization has membership criteria that
exclude non-members; in this case, youth are non-members.

The aspect of adulthood that seems least like an organization is the fact
that you don’t have to do anything to join — as soon as you turn 18, you’re
automatically inducted in. However, there may be precedents for other
organizations that function like this; perhaps churches that baptize you before you
understand their beliefs are an example.

Another thing that may seem wrong about the metaphor is youth’s lack of op
position to becoming members. If youth are truly oppressed by adults,
wouldn’t there need to be some sort of political conversion experience, where youth
denounce their former membership? …I think the reason we don’t see this is
because most youth spend their 18 years of “childhood” just wishing they could
hurry up and join. There is little sense of “joining the enemy” because most
youth identify with adults’ point of view; it’s an issue of assimilation —
as with Jews who want to dissociate from their Jewishness, queers who want to
“act straight”, or immigrants of any nationality that want to blend into
America’s “melting pot”.

Within the “adults as organization” model, “youth” is not an organization
in itself, parallel and equal to “adults”. Youth are an unorganized people,
defined by their exclusion from the group “adults”. Historically, young
people have been seen as the living property of adults in the eyes of the law.
Things have changed enough that we can forget this fact, but evidence remains
embedded in our language. Young people severing themselves from their parents
become “emancipated” — like freed slaves; running away remains illegal, again,
as it once was for slaves.

Organizations often have mission statements. If “adults” had one, what
would it be? To some extent all-adult government arises because most youth
aren’t up to the job of running the state, in which case, the “purpose” of the
organization would not directly address youth or age. However, given that youth
are specifically excluded from participating in democratic decision-making,
and the history of youth being treated like property, I would argue that the
mission statement could be articulated as “to control youth”. Others might
argue that the intentions of adults are beneficent in current society, so “to
protect and serve” would be a better fit. However, even if that were the intended
goal, the means to this end is total control.


One reason I like the “adults as organization” model is because I feel it
helps spell out what options for action I have as an adult. Just because I
am granted membership doesn’t mean that I have to identify with the group, or
support the policies it makes. Within an organization such as “adults”, there
are three main positions that can take: you can be a leader, a passive
member, or a conscientious objector.

Leadership might mean holding a formal position (e.g. as a senator), or
it might mean being an opinion-shaper (e.g. an author who writes about
child-rearing). If you have a movement of other adults behind you, you essentially
become a “caucus” within the organization. “Adults” is a large enough group to
tolerate a great deal of internal dissent — like the Democrat and Republican
parties do, for instance.

Being a passive member, you don’t necessarily even think of yourself as
an adult. An unmarried, baby-faced, fan of rock’n’roll might not feel like
they’re a “real” adult. Regardless of how this person feels, though, they still
possess basic privileges that minors don’t: the right to vote, buy alcohol,
rent a car, etc. A person may simply not recognize the ways in which they
identify with adults. In looking for your own hidden sense of adulthood, try
asking yourself this: “When there are debates on TV about young people, in my mind
do I think of the youth as ‘them’ or ‘us’?”

If “adults” is an artificial category, projected onto real physiology,
around which a powerful organization has been built — then a person can choose
to be a “conscientious objector”, instead of just accepting adulthood as
inevitable . There are several ways to approach this concept…

Focusing on the history of adults claiming to own youth as their
property, persons who are adult-by-membership can become “age abolitionists” —
attempting to dismantle the legal institution of childhood, just as slavery was
dismantled. Recognizing that this position sets them in opposition to the
majority of other adults, such people could proudly call themselves “age traitors”
(akin to the once derogatory term “race traitor”).

As an organization, adulthood has its own sort of “dress codes”. An
adult-by-membership can choose to break the dress code by wearing styles
associated with youth: dyed hair, baggy pants, bright primary colors (associated with
very young children). This action could be called “age bending” (akin to
“gender bending”). Intentionally mixing adult- and youth-identified clothes with
the intent to shock could be call “age fuck” (akin to “gender fuck”).

There are several good arguments for age-bending. It’s a way of
challenging the idea that adults and youth should dress differently. It can be a way
of visually showing that you stand with young people. It can be part of a
larger commitment to remaining culturally informed about what’s going on with
youth, instead of ignoring or putting down youth fashions. It can be a part of
trying to be a more whole human being, rather than cutting off the parts of
oneself that are “childish”.

Age-bending can extend to behavior, as well as fashion. The ideal of
“maturity” puts value on character traits such as “serious”, “stable”,
“unemotional”. The opposite characteristics, associated with youth, are typically
stigmatized. However, traits such as “playful”, “fluid”, and “emotionally engaged”
can be reclaimed an given new respect. Adults can model this work by
embodying such virtues, explaining their motives, and doing so with mannerisms that
are recognizably “young”.

The notion that human beings are either “adult” or “young” in nature
could be called “age dualism”. I’ve occasionally heard adults talk about their
younger selves as if they were separate persons, putting down those younger
selves in order to look bigger, just as they might put down any other young
person. I offer term “age monism” to describe an alternative: seeing one’s earlier
life and present life as a continuum, embracing and respecting the person one
used to be, even if you would choose to make different choices today. This
is the path of trying to be an “ageless being” — neither “adult” nor “young”
in nature, but instead the best of both, or something else entirely. “Ageless
being” is about trying to be a person that transcends age — even while
acknowledging one’s involuntary membership in the organization “adults”, and the
privileges that it confers.


How should we define “adults” and “youth”, and where is the line between
the two? I think the question has been answered at this point, but let’s put
all the pieces together now, as a way of summarizing…

The most common ways of answering this question involve defining “adults”
and “youth” in terms of biology, law, or personal character. I propose an
alternate model, one which encompasses those three approaches: adults as an

Prior to the emergence of law-based governments, gerontocracy (rule by
the oldest) was a fairly common occurrence. By creating laws that discriminate
against both the young and the old, adults as a class have ascended to power
— establishing modern adultism.

On top of actual physiological differences, adult-only government has
superimposed the artificial concepts of “adult” and “youth”, and made them real
by passing age-based laws. Adults, out of desire to dissociate themselves from
youth (or at least youths’ powerlessness), have created a separate culture of
adulthood: dress codes of clothing; adult-identified mannerisms, interests,
and language; the set of valued personal qualities collectively known as

Viewing “adulthood” as a largely artificial invention, we’re likely to
see “the line” between “adults” and “youth” as primarily a legal one.
Particular laws vary, but we can see the logic behind them: just as there are
children, parents, and grandparents within a family, society is organized into minors,
adults, and senior citizens. As a group, youth are most defined by living in
the homes of their parents, upon whom they remain financially dependent.
Considering the bulk of laws and their apparent intent, I conclude that it’s best
to define youth as “people under the age of 18”. However, because people in
the early years of adulthood still lack some privileges and suffer much of the
stigma of youth, I advocate recognizing “tweeners” (ages 18 – 25) as an
important subgroup of adults, strong potential allies to actual minors.

The “adults as an organization” model draws a sharp distinction between
membership and identity. Whereas membership is involuntary, a legal adult can
still disagree with the policies of the adults-only government, and identify
with the point of view of youth fighting the system. This is an exciting
possibility: adults can be “conscientious objectors”, “age abolitionists”, “age
traitors”; they can “age-bend”; they can aspire to transcend categorization in
their personal lives as “ageless beings”.


In conclusion, it seems apparent to me that how a person defines “youth”
and “adults” is going to have a major impact on how they choose to work
against adultism, or more generally for the interests of young people. I advocate
promoting the “adults as an organization” model in the future. I believe the
level of clarity it can provide, combined with the concise options for action
that it suggests, give it obvious advantages over the “biology”, “law”, and
“personal character” models of age. It will give Youth Liberation a better
foundation to build upon.

And how can a Youth Liberation movement with better thinking help but
become more effective?
