It is my experience that any discussion about strengthening
the social safety net for the economically disadvantaged quickly meets
resistance via two types of objections. One of these holds that the less
fortunate are by and large lazy and lackadaisical who would rather exploit the
benefits of the social welfare system than earn an honest living. The second objection
is usually posed as the following question: if they are so poor, why do they
have so many kids?
In this column I intend to tackle the second question about
the poor having many kids. Here the obvious conclusion that one must draw is
that the poor are poor because they have so many kids who need to be fed and
clothed; if only they did not procreate with such fecundity, then they can
easily find a way out of poverty.
It turns out that this implied causality is utterly
incorrect. It is not the case that they are poor because they have so many kids
but rather that they have more children because they are poor.
There are different ways of thinking about this. Let me
explain.
The evidence suggests that across the world citizens of
richer countries tend to have fewer kids compared to those in poorer countries.
So the birth rates in countries like Sweden or Switzerland are much lower than
those in Bangladesh and sub-Saharan Africa.
But even within the same country birth rates (typically
number of live births per thousand persons) start to drop as income levels
rise. This has happened in recent years in many developing countries such as
India. Even within the same country this pattern is evident. The birth-rate in
India’s poorest state of Bihar is almost twice that in richer states like
Kerala or Tamil Nadu.
There are many reasons behind this. Part of the answer comes
from evolutionary biology. For one thing, in poorer societies where many children
die in infancy, people tend to have more children so as to ensure that at least
some of those children live to adulthood. Furthermore, in countries with
inadequate social security and retirement benefits, parents often rely on
children to take care of them in old age. Here again it is important to make
sure that you have children who survive long enough to take care of the
parents.
In many third world countries – which may not have child
labour legislation - children can also be a source of income as they can be
sent off to work in the field, in the local tea-shop or as domestic servants.
But as income levels rise, birth rates fall. With rising
incomes, there are more opportunities including for women. Now the cost of
having a baby needs to be considered against the consequent loss of income from
her wages, a trade-off that was not required when jobs for women were few and
far between.
Clearly then the way to get women to have fewer babies is to
increase their options and income; with increasing income and education birth
rates fall.
But what does this have to do with the poor in a rich country
like New Zealand? Clearly compared to the poor in Bangladesh, the poor here are
far better off. So how come they have more kids?
It is worth pointing out that this finding is also widespread.
Even in rich countries, the socio-economically disadvantaged tend to have more
children.
How much more? According to data provided by Statistics New
Zealand our average fertility rate (roughly the average number of babies per
mother) is 1.96. For Asians and Europeans the rates are 1.67 and 1.77
respectively. For Maori it is 2.59 and for Pacific Islanders it is 2.94. So
yes, on average, the Maori and Pacific Islanders do tend to have more children
than Asians or Pakeha.
There is certainly a difference, but not a large one, as
some tend to think.
Where does this difference come from? There is an
approximate childbearing age, roughly between 15 and 49. How are some mothers
managing to have more kids?
The answer is that some – particularly those who are
economically worse off - are having kids at a much earlier age. For instance
looking only at 15 through 19 year olds the fertility rates among Maori and
Pacific Islanders are two to four times higher than the national average.
But in understanding what is driving early pregnancies among
some groups, one needs to think a little more deeply about the choices facing
young people.
Having a baby is a choice and like most choices it involves
trade-offs. For women from more privileged backgrounds, child-bearing at an
earlier age is very costly in terms of the sacrifices this involves, in terms
of their education, their careers and their foregone income.
But research undertaken among young and welfare-dependent
mothers in low income neighbourhoods of Philadelphia suggests that they
perceive no strong impetus to postpone child-birth since they have limited
other options and no sterling careers to look forward to. The same seems to be
true among the economically disadvantages in most rich countries.
Why does this perception persist? Surely in countries like
New Zealand there are plenty of opportunities for young people of all
backgrounds.
It is entirely possible that this view of having limited options
is mistaken but the perception, if it exists, may be enough to guide
child-bearing choices; or may be the perception is closer to reality and the hurdles
that need to be overcome on the path to rewarding careers are indeed much more
formidable.
Current evidence suggests that children born in poverty
continue to suffer disadvantageous after-effects in a wide variety of ways. Many
– if not most - of these are not in their control.
The bottom-line is inescapable: deprivation leads women to
have more kids; kids are not the primary cause of that deprivation.
