In

for
the
first
time
in
more
than
130
years,
adults
ages18to34were
slightly
more
likely
tobe

among

has
been
livingwith

This

of

18-to

It's
worth
noting
that
the
overallshare
of
young
adults
living
with
their
parents
was
not
at
a
record
high
in
2014.
This
arrangem
ent
peaked
around
1940,
when
about
35%of
the
nation's
18-to
34-
year
-olds
lived
withmom
and/or
dad
（compared
with
32%
in
201

haschanged,
instead,
is
therelative
share
adopting
differe
ntways
of
living
in
early
adulthood,
with
the
decline
of
romantic
c
oupling
pushing
living
at
home
to
the
top
of
a
much
less
uniform
l
istof
living
arrangements.
Among
young
adults,

In

8%of
youngmen
were
living

Young
women,however,
arestill
more
likely
tobe
living
with
aspouse
of
romantic
partner（35%）than
they
aretobe
living

parent（s）
（29%）.
[F]
In
2014,more
young
women（16%）than
young
men（13%）were
heading
up
a
householdwithout
aspouse
or
partner.
Thisismainly
because
womenare
more
likely
than
men
to
besingle
parents
livi
ng
with
their
children.
For
their
part,
young
men（25%）are
more
likel

than
young

The
average
age
of
fir
st
marriage
has
risen
steadily
fordecades.
In
addition,
a
growing
sh

young
adult
may
be

altogether.

In

both
employment

and

ha
velikely
contributed
tothe
growing
share
of
young
adults
who
are
living
in

of
their

and
this
is
especially
true
of
young
men.

The
share
of
young

with
jobs
peaked
around
1960
at84%.
In
2014,only71%of1
8-to34-year-old
men
were
employed.
Similarly
with

young
men's
wages
（after

have
been
on
a
downwa

and

As

has
risen.
