China After the Dividend

Will it overcome its demographic decline?

In a recent post, we described China’s unprecedented success at realizing a demographic dividend starting in the 1990s until around 2010. We discussed the confluence of factors that made this dividend possible. In this post, we look at present conditions and try to discern what is in store for the future. We use our usual approach and look at the three main pillars of wealth creation: Demographics & Health, Innovation & Productivity, Society & Governance.

Demographics & Health

The first thing that is evident is that demographics is no longer a positive vector of economic growth. 

The tailwinds created by a falling dependency ratio have died down and are now expected to turn into headwinds (see chart in our first post). The dependency ratio fell between 1970 and 2010 and was a key driver in the country’s GDP acceleration in that it opened a window of opportunity to realize a demographic dividend. China was able to realize that dividend because 1) it had liberalized its economy and opened up to trading with the world, and 2) it had improved its levels of education and infrastructure. As things stand today, the dividend has been fully realized and is behind us. There is instead a risk of a reverse demographic dividend, in which deteriorating demographics create a drag on growth, if China is unable to implement counteracting measures.

This risk is illustrated in the first chart below which shows the Chinese population by age groups. The population aged 15 to 64, aka the working-age population, soared between 1965 and 2015 and is now set to decline, slowly for the next decade but more rapidly thereafter. Meanwhile the population aged 65 and over will more than double between now and 2055. Finally, the youngest group aged 0-14 will taper off for decades to come.

Using the same data, the next chart shows the difference between the number of workers (those aged 15 to 64) and the number of dependents (those aged less than 15 and more than 64). The coming decline is as dramatic as the rise was in past decades. In 2015, there were 636 million more workers than dependents. But by 2055, this figure will fall to 189 million, or about the same as in 1980. Yet during this period, 1980-2055, the total Chinese population will have grown from 1 billion to 1.37 billion. (See in this article how the working-age population of other countries will have evolved between 1960 and 2050).

In addition to the longer term rise in the dependency ratio, China is seeing more recently a decline in its birth rate. China’s total fertility rate (TFR) fell to 1.09 children per woman in 2022, a new low in a recent downtrend that started after 2017. The next chart shows the evolution of the TFR since 1950. Note that it had fallen from over 6.0 to 2.75 before China enacted its one-child policy in 1980. Between 1991 and 2019, the TFR hovered between 1.5 and 2.0 but it fell below 1.5 in 2020 and fell again in 2021 and 2022.

Future Hubs of Africa and Asia

Editors

On UN projections between 2015 and 2050, the world population will grow by nearly 2.38 billion people, from 7.35 billion to 9.73 billion. Although this 32% growth is a big increase, it marks a slowdown from the 66% growth rate recorded in the preceding 35 years (1980-2015). Total Fertility Rates (TFRs) have come down all over the world and are expected to continue falling.

About half of the 2.38 billion increase will take place in sub-Saharan Africa and nearly 40% in Asia. India is the biggest contributor with a net addition of 394 million, followed by Nigeria (216m), Pakistan (120m), DR Congo (118m) and Ethiopia (89m). By 2050, all of these countries will feature in the top 10 populations by size, a list that will include the United States (expected to rank fourth) but not one European country. Outside of Africa and Asia ex-China, regional populations will be growing slowly (the Americas), stagnating (China, Europe), or receding (Japan, Eastern Europe). Read more →

Notes from the Wharton Africa Business Forum

Editors

The Wharton Africa Business Forum took place in Philadelphia on November 3-5, 2017. Present were the Finance Minister of Nigeria, the CEO of Ethiopian Airlines and other business leaders (notably from lead sponsors McKinsey & Company and the Boston Consulting Group) and educators. The event was attended by hundreds of participants including Wharton faculty, students and alumni, African investors and entrepreneurs, members of the African diaspora and many others who have an interest in Africa.

These are our notes from the event. They are not intended to be comprehensive.

First, there was a tremendous amount of energy and optimism surrounding Africa developments. There were a palpable sense that Africa’s moment is coming and an urgency that it should not be squandered. These sentiments are validated by our analysis of African demographics that show a coming decline in the dependency ratio and an accompanying increase in the odds of realizing some demographic dividend. However, fertility rates remain too elevated and are not falling fast enough to deliver the massive dividend that was seen in China, the US and Europe in recent decades. Read more →

Africa: 800 Million Jobs Needed

Editors

African economies are in a race to get ahead of the demographic boom.

“Let us share without fear the journey of migrants and refugees.” Pope Francis (@Pontifex) tweet on 27 September 2017.

While some people in the United States are sweating the presence, against the backdrop of a demographically stagnant white population, of the 11 million undocumented immigrants or of the 30+ million other foreign-born residents, there are far bigger numbers brewing in other parts of the world, numbers that are so large that they could affect, decades from now, the life of an American citizen far more than would the rare determined Mexican or Guatemalan who manages henceforth to scale President Trump’s purportedly impenetrable border wall.

In the next decades as was so often the case in history, the future shape of the world could once again be decided in Europe and by Europe’s and the West’s handling of Africa’s incipient demographic boom.

In fact, if you are a generous-minded European who shares the Pope’s noble sentiment and who views the ongoing wave of migrants coming into your country as a benign and positive development; or, if you believe that borders are outdated constructs and that all refugees and other immigrants should be welcomed into the rich world; indeed, if it is your view that anyone who stands in the way of this openness is misguided by racist and nefarious motives, then it behooves you to test the strength of your belief by examining the larger demographic data coming out of Africa and Asia.

New Infrastructure in Sub-Saharan Africa

Editors

This post will be continuously updated as we learn about new projects. Go to the bottom of the page for new entries.

On the three main vectors of wealth creation, African countries have lagged other developing nations for several decades. Sub-Saharan Africa is the poorest region of the world and suffers from poor infrastructure, uneven literacy, endemic corruption, political instability and war. While this is problematic for the present, improving conditions are pointing to a more promising future.

In particular, sub-Saharan Africa could have a unique opportunity to realize a demographic dividend if its elevated fertility rate and dependency ratio decline in the same way as have those of other countries in the past.

The experience of China shows that a significant dividend can be reaped if other conducive factors are also present. Most important among them are a growing workforce that is more literate and productive, and an institutional framework that is supportive of economic development. Read more →

The Economics of Dependency

SAMI J. KARAM

This article first appeared at Foreign Affairs.

How countries hit the demographic sweet spot.

Demographics are among the most important influences on a country’s overall economic performance, but compared with other contributors, such as the quality of governance or institutions, their impact is underappreciated. Demographic factors, such as the age structure of a population, can determine whether a given economy will grow or stagnate to an even greater extent than can more obvious causes such as government policy.

One of the most consequential aspects of demographics as they relate to the economy is a phenomenon known as the “demographic dividend,” which refers to the boost to economic growth that occurs when a decline in total fertility, and subsequent entry of women into the work force, increases the number of workers (and thus decreases the number of dependents) relative to the total population. The demographic dividend has contributed to some of the greatest success stories of the twentieth century, and countries’ ability to understand and capture this dividend will continue to shape their economic prospects well into the future.

Learning from Medellín with Alejandro Echeverri

Editors

“I think, if you want to write a new narrative at some specific moment in the story of a city, it is important that you have to feel the transformation and see the transformation. So the physical transformation is important but always there is more a spiritual thing, as happens with emotional connections and inspirational things.” ______Architect Alejandro Echeverri.

EcheverriPhotoIf you have an interest in Latin America or in urban matters, you will have read by now that the city of Medellín, Colombia has undergone a startling transformation in the past fifteen years. In the 1980s and 1990s, the name of Medellín evoked fearsome drug cartels, violence and terrorism.

But in the 2000s, Medellín took a dramatic turn for the better. In 2012, it was selected from 200 contenders as Innovative City of the Year in a survey organized by the Wall Street Journal and the Urban Land Institute. Today, it features regularly among lists of forward-looking cities and must-see destinations. Read more →

A Rough Estimate of GDP Growth in Africa and Asia

Editors

It is morally right that every child should be given the best chance to survive, eat well, stay healthy, and receive an education. Now we also know that it is among the best investments we can make. Healthy, well-educated kids grow into productive adults, capable of providing a better future for their own children, creating a virtuous circle that can help build a better, more prosperous world.   Bjorn Lomborg, Copenhagen Consensus.

In coming years, the global economy is going to need all the help that it can get. All countries of the West face a severe demographic challenge from the twin effect of an aging population and a large inflow of foreign migrants. Technology and innovation will continue to be powerful drivers of the economy but they will only partially offset the sluggish aggregate demand seen in richer countries. Read more →

Conference Brief: ‘The Modi-fication of the Indian Economy’

Providing Electricity to Africa by 2050

Editors

How many Africans will have access to electricity by 2050?

According to the World Bank’s latest figures, 64.6% of the population of sub-Saharan Africa lacked access to electricity in 2012, or a total of 572 million people. Across the world, 1.09 billion have no access to electricity. So, sub-Saharan Africa accounts for more than half the total.

Given the expected boom in the African population and the likely increase in access, the demand for electricity infrastructure is going to explode between now and 2050. On UN estimates (medium variant), the sub-Saharan population will jump from 886 million in 2012 to 2.1 billion in 2050. Assuming that each country’s current access rate remains the same, 381 million additional people will have access to electricity and 855 million additional people will not. Read more →
