- The world is an unequal place.
Let's consider Japan.
People in Japan live up until the age of 84 on average.
That's combined, the men and women.
People in the US can live up until the age of 79 on average.
And France does pretty well;
they live on average up until the age of 82.
Well, let's consider Angola and the Congo.
Average life expectancy is 51 and 52 years.
Wow! That's a pretty big difference, huh?
Thirty years different to France and Japan, at least.
What about India?
India, people live up until the age of 66 years.
As we can see throughout the world,
there's a tremendous amount of variation in life expectancy.
Life expectancy can be a mix of many different things.
Access to food, access to healthcare,
access to vaccinations,
access to clean water and sanitation.
We can see that there's a tremendous range.
Angola and the Congo are some of the lowest
life expectancies in the world.
Japan and France and the US are among some of the highest.
This shows you some of the big variation.
Let's not just take life expectancy, let's take water.
Access to an improved water source or cleaned water.
In the US, almost everybody has access to clean water.
In Europe, the story is fairly similar.
Half of the large parts of Central and Western Africa,
access to clean water is very difficult
for a substantial number of people.
In fact, up to a third of people may not have access
to clean water sources.
As we can see already, just by looking at life expectancy
and access to clean water,
the world does look like an uneven place.
What we're really looking at here is
global inequality.
Something else is pretty useful to do when we're looking
at global inequality is to draw a champagne glass.
The reason why drawing a champagne glass is really useful
because the champagne glass can help to explain
the inequalities in income that we see.
The inequalities in wealth that we see globally.
Because the champagne glass represents the
distribution of wealth globally.
Now, if we break down the global population to fifths,
and we take the top fifth ...
in fact, we call them the richest fifth.
The richest fifth have
82.7% of the global income.
What about the poorest fifth?
The poorest fifth, on the other hand, barely get a look in.
They barely see any of that income.
They get 1.4% of the global income.
What about the 60%, the 3/5 that are in the middle?
The mathematicians amongst you must have
already worked it out.
They get less than 16% of the income between them.
As we can see, this glass analogy works pretty well,
because the richest, by far, are getting all the money,
all the income.
They're getting the vast majority.
There's another interesting fact that I want you to know,
the richest 85 people have got more wealth than
the poorest 3.5 billion people in the world.
As we can see that there are great inequalities in wealth.
There are richer countries, poorer countries,
and there's a great deal of inequality
in individual countries.
Countries that are classed as being relatively
disadvantaged, relatively poor, within them
may have extremely rich people, and there can be
a great deal of income disparity within those countries.
We mentioned wealth; let's move on to health.
Let's take our champagne glass
and let's turn it upside down,
because one of the things I really want to talk to you now
is the maternal mortality rate.
This is the rate at which mothers die around childbirth.
This is super important.
This is a great marker for how effective,
and how good the healthcare systems are.
Now, I drew the champagne glass upside down,
because one of the things we know is that across the world
there is a great deal of difference
in terms of how many people die in childbirth.
We start right at the top.
We know that in Northern Europe
and in America, between 10 to 20 per 100,000 women
may die as a result of childbirth,
so the rate is relatively low.
As we go to, for example, South America, the rate increases
to say, 75 per 100,000.
As we can see, that's gone up.
Now we start to rise.
In Southeast Asia, 170 per 100,000.
Now, as we can see, we're looking at right at the top
of this upside down champagne glass.
Here, we have Central and Western Africa.
The rates here are 700 or more per 100,000.
If we consider maternal mortality to be a marker
of a healthcare, system's healthcare delivery,
we can see that the stem of the glass,
we've got relatively low numbers, right?
Europe, 10, and then we compare that
to Central and Western Africa, over 700.
That's a 70-fold increase in risk.
As we can see that these numbers are pretty dramatic.
This is a champagne glass you don't want to be
towards the bottom of
unlike our previous statistic.
As we can see, global inequalities are rife, whether we look
at them in terms of access to water, access to wealth,
or in terms of healthcare delivery.
