Abstract
When
the
COVID‐19
pandemic

in
early
2020,
speculation
was
rife
both
public
and
academic
spheres
over
its
possible
effects
on
birth
rates
partnership
behavior.
Now,
four
years
later,
we
still
know
surprisingly
little
about
effect
of
fertility
family
dynamics.
In
this
paper,
outline
three
main
takeaways
from
scientific
literature
produced
topic
past
years.
We
argue
that
(1)
do
not
have
enough
data
to
answer
basic
questions
dynamics,
(2)
suggest
an
unexpectedly
incoherent
heterogeneous
response,
(3)
estimated
are
suspect
since
shifting
theoretically
unexpected
prepandemic
behavior
made
identifying
a
strict
causal
problematic.
