Child Mortality

3Since the beginning of the age of the Enlightenment and over the course of modernization, the mortality of children below 5 years of age has declined rapidly. Child mortality in rich countries today is much lower than 1%. This is a very recent development and was only reached after a hundredfold decline in child mortality in these countries. In early-modern times, child mortality was very high; in 18th century Sweden every third child died, and in 19th century Germany every second child died. With declining poverty and increasing knowledge and service in the health sector, child mortality around the world is declining very rapidly: Global child mortality fell from 18.2% in 1960 to 4.3% in 2015; while 4.3% is still too high, this is a substantial achievement.

One reason why we do not hear about how global living conditions are improving in the media is that these are the slow processes that never make the headlines: A century ago every third child died before it was five years old, almost a century later the child mortality rate has fallen to 4.35%. We will not learn about this development from the news as such a slow development is never fast enough to make the a headline. The headline that could have been published on every average day in the last century is “The global child mortality rate fell by 0.0008 percentage points since yesterday”.1

Big countries like Brazil and China reduced their child mortality rates 10-fold over the last 4 decades. Other countries – especially in Africa – still have high child mortality rates, but its not true that these countries are not making progress. In Sub-Saharan Africa, child mortality has been continuously falling for the last 50 years (1 in 4 children died in the early 60s – today it is less than 1 in 10). Over the last decade this improvement has been happening faster than ever before. Rising prosperity, rising education and the spread of health care around the globe are the major drivers of this progress.

Empirical View

Global decline of child mortality

One reason why we do not see progress is that we are unaware of how bad the past was.

In 1800 the health conditions of our ancestors were such that 43% of the world's newborns died before their 5th birthday. These estimates are shown in the visualisation below.

In 1960 child mortality was still 18.5%. Almost every 5th child born in that year died in childhood.

Over the last decades we have seen a very rapid decline of child mortality globally. In 2015 child mortality was down to 4.3% – 10-fold lower than 2 centuries ago. You have to take this long perspective to see the progress that we have achieved.

Estimates for child mortality over the last two centuries

The world map shows the estimated level of child mortality for all world regions in 1800 in the country borders of today. In all parts of the world child mortality is estimated to be higher than one third.

The estimates for the period from 1800 to 1949 were produced by Gapminder2 and especially for the early period the uncertainty of the estimates is very high for many world regions.

Country by country decline in child mortality

In the time series plot below I show child mortality over the long run for countries. Today child mortality in industrialized countries is below 0.5%. The time series plot shows that these low mortality rates are a very recent development, and in pre-modern countries child mortality rates were between 30% and 50%. In the late 19th century, every second child in Germany died before its fifth birthday. In developing countries the health of children is quickly improving – but child mortality is still much higher than in developed countries.

A second interesting characteristic that is immediately noticeable is that the series are very 'spikey' in the 19th century and are then much smoother in the 20th century. This is partly because the data quality is improving over time but it also shows how frequent crises were in pre-modern times. The decline of crises is an important aspect of improving 'living standards'. In our entry on food price volatility you find a long-run series in Pisa that shows how frequent food crises were. In the following plot you can see what these and other crises – epidemics or wars, for example – meant for the health of the population.

Global picture of child mortality from 1800 until today

The chart shows the child mortality rate – the share of children dying before they reach the age of 5 – for the entire world population at 4 different points in time.

How to read the following graph: On the x-axis you find the cumulative share of the world population. The countries are ordered along the x-axis descending by the country’s child mortality rate. This makes it possible to see the child mortality rate for each country. Some countries are labelled, but not all. It is also possible to see which share of the world population had a child mortality rate lower than a given level. For the orange line – referring to data from 1950-60 – we see that close to 70% of the world population have a child mortality rate of higher than 10% back then.

For 1800 (red line), you see that the countries on the very left – Yemen, India, and others that are not labelled – had a child mortality rate higher than 50%. Every second child died before the age of 5. On the very right of the red line you see that in 1800 the best-off countries in the world had a child mortality rate higher than 30%: Every third child died in the countries with the best health.

Looking at the orange line, you see that in the following 150 years some countries substantially reduced their child mortality rate: 30% of the world population has a child mortality under 10%. Other countries were stuck in poor health: More than half of the world (57%) had child mortality that were still higher than 20%. The world was clearly divided into developed and developing countries. The rapid progress of the industrialized countries had the consequence that the distribution of global health was hugely unequal.

The latest data refers to 2013. Global health has improved hugely. Particularly those countries that had the worst health in the 1950s experienced the most dramatic improvements. China for example reduced its child mortality from 28.4% to now 1.3%. The consequence of the faster progress in former developing countries is that global health inequality has fallen since the 1950s.

The global average child mortality rate (weighted population) was 43.3% in 1800 and now fell to 3.4%. Focusing at global inequality we see that in 1800 health was bad around the world, in the 1950s the world became unequal, and today we are back to higher equality but on a much higher level.

Comparing the position of countries on the red, orange, green and blue lines also makes it possible to see the change in a single countries: In 1800 every second child in South Korea died, in the 1950s the rate was halved (26%), and today it is down to 2.7%.

The child mortality rate – country by country

The following visualisation shows the child mortality rate for all countries in 1955 and six decades later.

Catch-up improvements in child mortality

In the chart below we compare the period over which it took a range of countries to reduce child mortality from one-third (1-in-3) of children dying before their 5th birthday, down to 1-in-20 (5%). Also noted here is the start and end date by which this was achieved.4

Here we see that countries which industrialized rapidly during the 19th century (many countries across Europe), it took more than century (as high as 148 years in the case of the UK) for child mortality to fall from 1-in-3 to 1-in-20. If we look at countries who achieved this in the late 20th or early 21st century, we see that this reduction was much faster. Many (across all regions) achieved this in under 50 years. South Korea achieved it in only 25 years.

Whilst progress may at times seem persistently slow, we see that fast catch-up improvements are possible. What it took today's rich countries centuries to achieve, many are now achieving within decades.

Child mortality catch up improvement

Child deaths over time

The data presented above shows the rate of child deaths. The absolute number of child deaths also depends on the absolute number of births and is shown in the following chart.

In the late 1960s close to 20 million children died every year. Even though the number of births increased since then, the absolute number of child deaths started to decrease and from annually more than 20 million deaths declined to below 6 million deaths. The annual decrease of this reduction stayed remarkably stable over these five decades. In the period from 1990 to 2015 the world saw on average 272,169 fewer children die every year, while the number of births globally increased slightly. This means that over these 25 years the number of child deaths fell on average by 746 deaths every single day.

By clicking 'add country' it is possible to see this change over time for all countries in the world.

Child deaths by region

In the chart below we show the breakdown of global child deaths by region. Here we see the dramatic decline in child deaths in recent decades: the number of children dying each year has more than halved since 1990.

Child mortality in pre-modern cultures

In 'Longevity Among Hunter‐Gatherers' the authors, Gurven and Kaplan, compare mortality patterns of hunter gatherers and modern societies and state that "infant mortality is over 30 times greater among hunter-gatherers, and early child mortality is over 100 times greater than encountered in the United States".5

Child mortality globally post-1950

Globally child mortality has declined from 23% in 1950 to 4.5% today.

Though there are still large disparities between child mortality rates between different regions around the world, it is steadily decreasing in all world regions.

This chart shows the decline of child mortality by income level of the country.

Child mortality has declined in all countries of the world

The scatter plot below shows for each country the child mortality rate in 1970 and in 2015. It shows that the mortality rate has fallen in each country.

World map of child mortality

The world visualizes the level of child mortality country by country. By moving the slider to a later year one can study the global decrease in child mortality. In fact child mortality has decreased in every single country over the last decades.

Child mortality by cause of death

All causes of child death – globally

In a publication in The Lancet Liu et al. (2015)7 presented estimates on the causes of deaths of children in 2000 and 2013. The tree map below presents this data. Each rectangle corresponds to a cause of child mortality. The size of each rectangle shows the share of children killed by each cause. The three leading causes are preterm birth complications (15% of total; 0.965 million), pneumonia (2% in the first month, 13% later; 0.935 million in total), and intrapartum-related complications (11%, 0·662 million).

44% of all children died in the first month of their life. More than half of all children (51.8%) died of infectious diseases. The researchers report "deaths due to infectious diseases, such as

pneumonia, diarrhoea, and malaria, are concentrated in the first 2 years of life, which should direct programmes towards these very young ill children".

The color of each rectangle indicates the annual reduction of the mortality rate from that specific cause since 2000. Child mortality from all causes declined; the smallest decline (0.2%) was achieved for pertussis, also known as whooping cough; the largest decline was achieved for measles (12.8%) for which a vaccination is widely available. As the causes of mortality later in childhood are declining faster the researchers observe a shift in the timing of child deaths closer and closer to the time of birth.

The absolute number of children dying decreased: In 2000 9,887 million children died before they were 5 years old – 13 years later, 6,282 million children died. This happened while the absolute number of livebirths increased from 127,703 million in 2000 to 137,688 million in 2013.

Since cause of death data is not available for all countries in the world the researchers had to make use of three different sources of data: The preferred data was of course vital registration data; where not available Liu et al. (2015) estimated the cause of death with a multicause model, applying a multinomial logistic regression framework and when this was not possible they used a "verbal autopsy databased multicause model".


All causes of child death – globally over time

The following visualisation is following on the change over time and shows the number of child deaths by cause. The data comes from the IHME’s Global Burden of Disease study.

This visualization shows the many causes of child deaths and the mortality rate that they are responsible for. Birth complications, pneumonia, diarrheal diseases, and malaria all still lead to the death of more than 400,000 children annually.

In many cases, the comparison with 1990 shows that we are on track to a rapid reduction. But the breakdown by cause also highlights that preventable diseases are still responsible for an unacceptably large share of child deaths and we have the duty and the possibility to reduce child mortality further.

The five most lethal infectious diseases over time

The chart below focusses on the five most lethal infectious diseases. It shows the number of child deaths caused by these diseases from 1990 onwards.

Deaths caused by malaria and HIV/AIDS were rising over the 1990s. From 2005 onwards the deaths caused by each of these diseases is declining.

The most important disease referred to as 'lower respiratory infections' in the visualisation is pneumonia.

Child mortality by sex

The visualisation below that the mortality of boys is higher than the mortality of girls in the huge majority of countries around the world. Part of the explanation for this consistent difference across very different countries is that newborn girls have a biological advantage in survival over newborn boys. According to a UN (2011)8 report on the topic this is particularly due to girls' "lesser vulnerability to perinatal conditions (including birth trauma, intrauterine hypoxia and birth asphyxia, prematurity, respiratory distress syndrome and neonatal tetanus), congenital anomalies, and such infectious diseases as intestinal infections and lower respiratory infections".

Here is a visualisation of child mortality by sex as a line chart.

How many children did a woman give birth to that died before their 5th birthday?

The brutal reality of child mortality becomes clearer when one remembers what it means for each woman who loses her child.

The following visualization uses the data on fertility – the number of children born per woman – over time and combines it with information on child mortality over time. Taking these two time series together makes it possible to estimate how many children a woman on average lost before the children were five years old.

Below you see the data for Sweden which is one of the country for which we have the best historical data, the Swedish office for population statistics Tabellverket was founded as early as 1749.9 The visualization shows that throughout most of the 19th century Swedish women gave birth to more than 4 children. As we have seen above, child mortality in this period was often higher than 25%. Fertility and child mortality were so high that on average every woman lost 1 of her children before they could celebrate their 5th birthday. With the decline of child mortality and fertility this became very rare, in 2015 Swedish women lost on average 0.006 children before they were 5 years old.

In this visualization you can change the country for which this time-series is visualized to explore the trends in countries around the world. To compare the number of children lost per woman for several countries – and see the data on a world map – you can use this visualisation.

The data shown in this visualization is calculated based on the historical estimates of fertility and child mortality presented at (see the sources tab in the chart for more information); particularly for the early period data coverage is not as good as one wishes and it should be understood that the presented estimates are coming with a considerable uncertainty.

Neo-natal mortality

The neonatal mortality rate, shown in the following visualization, is defined as the share of newborns that die during the first 28 days of life (0-27 days).

Correlates, Determinants & Consequences

Child mortality and income level

As one would expect, income level of the country is extremely correlated with child mortality rate. The poorest countries have the highest levels of child mortality, and the countries with the highest income have the lowest rates. This relationship has remained the same even as child mortality has decreased around the world, as demonstrated below.

The following scatter plot shows that child mortality is higher in countries in which a higher share of the population lives in extreme poverty.

Inequality by socio-economic class

In absolute terms the inequality of life expectancy has decreased massively in the UK – the visualisation above showed that the Gini for life expectancy has declined from over .45 to below .1 in the beginning of the 21st century.

We can see below that the gap in infant mortality has narrowed significantly in absolute terms; there were 80 infant deaths per 1,000 live births for infants with fathers who were in unskilled manual fields, versus 32 deaths per 1,000 live births born to fathers with professional careers, representing a 2.5 times lower rate. Today, those absolute mortality numbers are only 7.4 and 3.8 respectively, but there is still nearly a two-fold difference in mortality rate. Absolute inequality has decreased dramatically, but the ratio between the two – a measure of relative inequality – has only decreased a little.

When considering how the inequality of child mortality has decreased, one has to take into account that the occupational structure has also changed – the share of people employed in the low-skilled sector has decreased. The authors of the data below – Floud, Fogel, Harris, Hong – add that the "differences are still apparent even after allowances have been made for the effects of changes in the occupational structure of the British population and selection effect".10

Better education of women reduces child mortality

There is a substantial literature on the effects of women's education on child mortality. A more educated female population is strongly associated with lower rates of child mortality as well as both human and economic development. Some of the suggested reasons for this relationship are summarised in the figure below.

The linkages between female education, human development and economic development - Brown and Barrett12

The linkages between female education, human development and economic development

Gakidou et al. find that over half the decline seen in child mortality globally between 1970-2010 can be explained by improvements in the education of women. What is more, they find that economic growth (GDP) can only explain a very small amount of the reduction in child mortality.

Explanatory notes from the authors: "The lines represent the actual child mortality rate (blue); estimated child mortality rate if GDP for each country had remained at the level it was in 1970 or 1990 (green); estimated child mortality rate if education of reproductive-age women for each country had remained at the level it was in 1970 or 1990 (red); and estimated child mortality rate if both GDP and education of reproductive-age women had remained at their 1970 or 1990 levels (purple)."

Counterfactual analysis of effect of education and gross domestic product (GDP) on child mortality globally with 1970 (A) and 1990 (B) as base years - Gakidou et al.13


Below we can see that a higher educational attainment by mothers is associated with lower child mortality rates within countries. For instance, Niger has the highest national average of child mortality, but within the country, mothers with a secondary school education or higher experience child mortality rates that are lower than the national averages of the next 16 countries listed.

The effect of education on child mortality is huge. Especially in places with relatively little education, the prospects for extending education are promising. In 2008, 4.4 million children younger than 5 years died in sub-Sahran Africa. The UNESCO estimates that an extension of secondary education for all women would save 1.8 million children per year.15

Health care and child mortality

In a publication in the American Economic Journal the authors report that Thailand's 2001 healthcare reform led to significant reductions in child mortality, especially among the poor.16 The following graph shows for a large cross-section of countries that high expenditure on health more generally comes along with lower levels of child mortality.

When more infants survive – fertility goes down

On the y-axis we measure the number of annual live births per 1,000 people. On the x-axis we measure how many infants, who were born alive, survive their 1st year of life – this is the infant survival rate.

The chart shows how these two aspects changed over the course of the 20th century: At the beginning of the century all 4 countries can be found in the upper left corner – they are characterized by high fertility and an infant survival rate below 85%. If we follow the 4 lines we are taken to the bottom right corner and see that women have fewer children when the mortality rate of babies goes down.

The causal link between infant survival and fertility is established in both directions: Firstly, increasing infant survival reduces the parents’ demand for children. And secondly, a decreasing fertility allows the parents to devote more attention and resources to their children.

This link between fertility and child mortality is an immensely important insight and tells us what drives the acceleration and slowdown of population growth: In the initial stage of the transition, when fertility rates are still high but health is already improving, the population starts to grow. But then, a bit later, we see that this transition works to decrease population growth since improving health of the children leads to lower fertility. It is an important part of the mechanism behind the demographic transition.

A very cynical view is that a decrease in child mortality is bad for the world since it would contribute to the overpopulation of the planet. The chart above shows that this opinion is not just contemptuous of human life but plainly wrong: When more infants survive fertility goes down and the temporary population growth comes to an end. If we want to ensure that the world’s population increase comes to an end soon we must work to increase child survival.

Infant survival and fertility through time – Max Roser17


Data Quality & Definition


Child mortality is the probability per 1,000 live births that a newborn baby will die before reaching age five under current age-specific mortality patterns.

Infant mortality is defined as the number of deaths of children under 1 year of age per 1,000 live births.

A neonatal death is defined as a death during the first 28 days of life (0-27 days).

The neonatal mortality rate is defined as the number of neonatal deaths per 1000 live births.

Data Quality

The uncertainty associated with the estimates of child mortality can be understood if one compares different data sources. The UN Inter-agency Group for Child Mortality Estimation does this for each country of the world. Here is the chart on the child mortality of Brazil as one example. On the same website the differences between various data sources can be studied for a large number of countries.

Wide within-country variation of infant mortality

Country averages of infant mortality sometimes obscure the variation in infant mortality between regions within the country. Storeygard, Balk, Levy and Deane (2008) assembled a data-set that looks at the sub-national distribution of infant mortality.18 The data set covers over 10,000 national and subnational units worldwide. It is benchmarked to the year 2000. Understandably, many of the countries with the highest national infant mortality averages have lots of subnational variation in these rates, but even some of the most highly developed nations still see massive variation in infant mortality at the regional level. The most extreme example is China, which experiences an infant mortality rate near 0 in some regions but a rate around 325 at the other extreme.
