What share of the population is male and female?
The sex ratio – the share of the population that is female – varies across the world. And globally in 2020 the share of women in the world was just under 50%. There are three reasons why the sex ratio of populations varies and is rarely equal: 1. differences in mortality rates and life expectancy for women and men. Women, on average, live longer than men. This means that all else being equal, we would expect females to account for slightly more than half of the total population. 2. sex ratios...
How does the sex ratio at birth vary across the world?
Across the world there are differences in the sex ratio at different life stages. This imbalance in the male and female population can in some cases be traced back to birth: in some countries the number of boys and girls born each year is significantly skewed. In the map we see the differences in sex ratio at birth across the world. Here the sex ratio is measured as the number of male births for every 100 female births; a value greater than 100 indicates there are more boys than girls born th...
The sex ratio varies with birth order
Most countries have a sex ratio at birth which is around the expected range of 105 boys born for every 100 girls. There are exceptions to this: there are countries – most notably in Asia – with highly skewed sex ratios in favor of males. The preference in some countries for a son is seen in the overall sex ratio at birth figures above. But this bias is even stronger when we look at how this ratio is affected by the birth order of children. In this visualization we look at the case of India an...
Sex ratio in childhood
Sex ratios – the ratio of males and females – at birth is male-biased across every country in the world; in our section on this, we explain why biologically we'd expect this to be the case. The so-called 'expected' sex ratio at birthwas around 105 males per 100 females. But how does this ratio look later in childhood? Does it change from newborns to five-years-olds? In the two charts here we see two perspectives: firstly a global map of the sex ratio at five years old. Just as with the sex ra...
Biology or discrimination: which countries have skewed sex ratios at birth?
Today, and at several points historically, the sex ratio at birth in some countries is too skewed to be explained by biological differences alone. The 'expected' sex ratio at birthis around 105 males per 100 females. In a recent study Chao et. al (2019) re-modelled sex ratios at birth (SRB) across the world based on a range of population sources, including census and household survey data.28 The results are shown in the chart below since 1950. The authors identified 12 countries with strong s...
Infanticide
Sex discrimination can occur prenatally (in the form of sex-selective abortions, as we discuss here) or postnatally when it can lead to the death of a child in the very worst cases. The death of a child due to sex discrimination can be brought about in a deliberate killing of an infant (infanticide) or can be caused by neglect or poor and unequal treatment. Over time, prenatal discrimination has increased as both abortions and sex determination technologies have become more readily available....
Excess female mortality
Poor treatment of girls results in increased mortality in childhood In almost every country young boys are more likely to die in childhood than girls – as we explore here, there are several biological reasons for is. But this is not true in a few counties – India is one notable example today. There, girls die more often than boys. When we compare infant (under one year old) and child (under-5s) mortality rates between boys and girls in India we see that the difference is bigger for the older...
In countries where there is a clear imbalance in sex ratio, there's preference for a boy. But why does this preference exist? Son preference is most common in countries across East and South Asia, but also in some countries in the Middle East and North Africa.69Although there are significant cultural, economic and societal differences between these...
Across several countries in Asia, and North Africa we see highly skewed sex ratios in favour of males. Strong preference for sons has led to an increasing number of "missing women" and therefore an "excess of males". There are a number of adverse consequences which could result from highly imbalanced numbers of men and women in society. These prese...
Are richer and more educated parents less likely to have gender preference?
If our aim is to address the issue of a skewed sex ratio and female discrimination, an obvious question to ask is: will development fix the problem? Is it the case that son preference is restricted to those at lower incomes, therefore the problem disappear if povertyfalls and societies develop? The evidence to date suggests, no: development on its own does not address it. Studies which have looked in detail at the extent of sex ratio imbalances by demographic (comparing income level, educatio...
Does banning prenatal practices reduce sex-selective abortion?
One of the three conditions for sex-selection is the abilityto act upon gender practices through access to technology. Prenatal sex selection (PSS) relies on two technologies: prenatal sex determination (the ability to determine the sex of a foetus during pregnancy) and selective abortion. This raises the question of whether policies that aim to regulate prenatal sex determination and abortion have an impact on the prevalence of sex selection. Several governments limited prenatal sex selectio...
Sex ratio at birth: the number of males born per 100 females. 'Expected' sex ratio at birth: the expected sex ratio at birth is not completely equal: under ordinary circumstances we would expect there to be slightly more boys born than girls. This means that in all countries, births are male-biased. The expected sex ratio is approximately 105 boys ...
