The lottery of birth

No child chooses where they are born, yet that single accident of geography largely decides whether they will see their fifth birthday, drink clean water, or grow up in poverty. Across 197 countries, a newborn's odds of survival range from 99.9% to below 89%. Scroll through the evidence, then spin the wheel and be born, at random, as one of the world's children.

01 The spread

The single most important number about a child

Under-five mortality, the share of newborns who die before their fifth birthday, is UNICEF's signature measure of child wellbeing. Across 197 countries it runs from just 1.3 per 1,000 births to 116.8. Each dot is a country; its size is its population, its colour its mortality rate.

02 By region

Almost all of it, in two regions

The deaths are not spread evenly. Sub-Saharan Africa carries a child-mortality rate many times higher than Europe or East Asia, and together with South Asia accounts for the overwhelming majority of the world's under-five deaths.

03 Income

Money buys survival

Plot each country's income per person against survival and the relationship is almost a wall: below a certain income, survival drops away fast. Poverty and child death are the same map, seen twice.

04 Water

And it isn't only survival

Swap the vertical axis for clean-water access and the cloud barely moves. The countries where children die youngest are the same ones where they are least likely to drink safe water, the disadvantages stack on the same children.

05 The draw

Spin the wheel. Where are you born?

You had no say in it. Press the button and be born, at random, as one of today's children, with the odds weighted by real population, so you are most likely to land where most children actually are.

Because most of the world's children are born in higher-mortality regions, the draw lands there far more often than a glance at a world map would suggest. Spin a few times.

06 The gap

80 times, and closing

A child born in the highest-mortality country is roughly 80× more likely to die before five than one born in the safest. Yet since 1990 the global rate has fallen by around 60%, proof the lottery can be re-rigged. Turning an accident of birth into a fair start is the daily work of organisations like UNICEF.

Data: World Bank Open Data · UN IGME · WHO/UNICEF JMP

Data & method. Under-five mortality, population, basic drinking-water access and income (GNI per capita, Atlas method) for 197 countries from World Bank Open Data (latest available, 2022–2023), drawing on the UN Inter-agency Group for Child Mortality Estimation and the WHO/UNICEF Joint Monitoring Programme. The "spin" draws a country at random weighted by population, so it reflects where the world's children are actually born. All charts rendered live in D3.
