Environmental factors such as nutrition, urbanization, health, or climate can all influence the development of children and adolescents. Looking across the world, the tallest men and women are found in Europe with a mean height of cm for men and cm for women, followed by Australia.
South Asians and South-East Asians tend to be the shortest with women having a mean height of cm and men of cm. Table 3: WorldData. Average sizes of men and women.
The country with the tallest women and men are found in Europe. Men from the Netherlands have the highest average height with The tallest women in the world live in Latvia with a mean height of cm 5 ft 6.
Until the second half of the 19th century, the Dutch were actually among the shortest people in Europe. However, due to a change of life quality and a better distribution of wealth, the Dutch became the tallest Europeans by the s. Currently, the shortest men with an average height of cm 5 ft 3 in live in Timor in South-East Asia, whereas women in Guatemala are on average only cm 4 ft Countries like Bolivia and Indonesia are among the poorest in the world and many children are chronically malnourished which leads to a comparable shorter stature in adult age.
Comparing stats from the last century to this, South Korean women and Iran men showed the largest increase in mean height over the last century. The height of Korean women has increased by 7. On the other side of the specter, the average height of the citizens in Sub-Saharan African and South Asian countries has changed very little in the same period. By contrast, one haplogroup I-M is most concentrated in Germanic-speaking Europe, and the Western Balkans, particularly Herzegovina.
These regions are characterised by tallness, which strongly suggests a correlation between this haplogroup and height. Is height determined by genetics or environment? The short answer is that it depends on the countries you are comparing. Differences in average heights could be due to different genes, different environments, or — more likely — some combination of both. For instance, the average male height in Bosnia and Herzegovina is cm — far higher than the global mean of cm, and even the regional mean of cm.
This height cannot be explained by high standards of living nor high animal protein consumption: its HDI is one of the lowest in Europe, and the ratio of animal protein to plant protein consumption is only 0. The cause in this case must be genetic: nature over nurture. Differences in average heights between North and South Korea tell a very different story, as told by Pak The two halves of the Korean Peninsula share a genetic lineage, but since the partition in there has been a great divergence in average heights.
While the average height of South Korean men increased by 3. This disparity is much more likely to be due to differences in standards of living: nurture over nature.
The equation that determines human height is made up of many components. No single factor can predict height at an individual or even a national level. But overall, average heights can offer a unique insight into the genetic makeup and standard of living of a population. We have looked in detail at how mean heights vary across the world. But this tells us very little about the distribution of heights globally, regionally or within in a given country.
How do heights vary: do most people have heights very similar to the average; or do they span a wide range? Adult heights within a population are approximately normally distributed due to genetic and environmental variance. Height is partly determined by the interaction of genes with variants. One of the basic rules of probability known as the Central Limit Theorem says the distribution of a trait that is determined by independent random variables, like height and genes, roughly follows a bell curve.
This means the range of human heights in a population fall centrally around the mean height. The normal distribution of heights allows us to make inferences about the range. If we know the mean and standard deviation of heights, we have a good understanding of how heights vary across a population.
Drawing upon height data from almost , twinned pairs born between and , one study investigated the variance in heights across populations through time, and tried to explain how much could be explained by genetics versus environmental differences. We see this distribution of heights in the chart.
As an aggregate of the regions with available data — Europe, North America, Australia, and East Asia — they found the mean male height to be Women were smaller on average, with a mean height of Regionally, the standard deviation of male heights is largest in North America and Australia, at 7. The pattern is the same for women, with 6. Some of the distribution of heights within a population is likely to reflect the degree of genetic variance.
Differences in height within a population are not only influenced by genetic variance. Greater environmental variance within a population is also reflected by a wider distribution of heights. The distribution of heights has therefore be used as one indicator of socioeconomic inequality in the past.
In a population with perfectly equal access to nutrition and health resources, height distribution would only reflect genetic variation. Unequal access to these resources within a population means that wealthier individuals could have better health and nutrition, and therefore tend to grow taller than poorer ones; variance of heights therefore becomes larger.
In other words, resource-based variance due to income inequality is added to genetic variance, widening the distribution of heights. Some empirical evidence across a range of contexts would support this hypothesis. Members of the high castes — who had better access to nutrition and health resources — were 4. Furthermore, Ayuda identified a relationship between socioeconomic status and height among Spanish conscripts from to Height inequality, which is measured by the coefficient of variation CV , is therefore positively correlated with income inequality, which is measured by the Gini coefficient.
This relationship was observed in a study of Kenya during the 20th century, where the CV mirrored fluctuations in the Gini coefficient. It also compared the height distributions of Uganda and Togo, where average heights were roughly equal, but there was higher income inequality in the former than the latter. Sure enough, the distribution of heights was wider in Uganda. So, both genetic and environmental factors have an impact on height variation. But which is the most important determinant?
Heritability is measured between 0 and 1; the higher the heritability, the larger the contribution of genetics. Twin and adoption studies typically estimate heritability at about 0. This means that the majority of the variation in height within a population is due to genetic variation, but environmental variation due to socioeconomic factors also has an impact.
Accurately measuring the height of an individual is a straightforward task and so we should be confident that there is relatively little measurement error in the recorded data. This is unlikely to be the case when measuring the height of skeletons. What is more, the techniques used to date skeletal remains such as radio carbon dating only provide a probabilistic estimate.
Another factor to consider is the potential sample bias from the historical sources. Since the height data is largely composed of soldiers, criminals, salves and servants, these groups may not be representative of the wider population. This problem has been highlighted by academics researching human height. In fact, the observed drop in height during the industrial revolution — usually attributed to the negative health impacts of industrialisation — can be explained by the labour market conditions that existed at the time.
By comparing the heights of soldiers in the US army with countries that enforced conscription we can see the bias more clearly. In countries that had conscription, the average height of conscripts was increasing over the period, meanwhile in the US where entry was voluntary, the heights of soldiers was falling.
