In 1494, an Italian monk named Luca Pacioli published an overview of the mathematics of his time. His 36-chapter work described what has since become standard knowledge among the world’s finance and business professionals and a building block of balance sheet accounting: double-entry bookkeeping. And since the advent of this method, invested capital has been the pillar of every enterprise, government, and economy. Even today, in the wake of the global financial crisis and amid a spreading debt crisis, invested capital remains the core and the promise of economies everywhere. But a much bigger crisis is yet to come—one that strikes at the very purpose of economies but is scarcely noted, let alone managed: the crisis in human capital.
Every economy’s ability to compete depends on a steady supply of human capital and talent. When that supply is inadequate, imbalances result, creating serious threats not only to the economy but also to social and political stability and future development. This impact, moreover, extends beyond borders.
Over the past few years, we have examined workforce supply-and-demand dynamics in 25 major economies (including the G20) through 2030.1 Notes: 1 See Stimulating Economies through Fostering Talent Mobility, a report by the World Economic Forum in collaboration with The Boston Consulting Group, March 2010; and Global Talent Risk: Seven Responses, a report by the World Economic Forum in collaboration with BCG, January 2011. Today, these countries collectively account for more than 2 billion economically active people, or around 65 percent of the world’s population—and more than 80 percent of total world GDP. This report highlights the impending labor shortages and surpluses and their implications for future growth. Trends across the 25 economies we studied are alarming: an equilibrium in supply and demand is rapidly becoming the exception, not the norm. Between 2020 and 2030, we project significant worldwide labor-force imbalances—shortfalls, in particular. One significant implication is the potential aggregate value of GDP squandered, because either these nations cannot fill the jobs available or they cannot create enough jobs for the workers they have. This represents a stunning $10 trillion—around 60 percent of U.S. GDP and more than 10 percent of total world GDP (according to the latest available 2013 figures).
This report, the first of a series on this topic, summarizes the findings of The Boston Consulting Group’s extensive research on global talent risk and outlines basic solutions to mitigate these imbalances. The series as a whole will describe the consequences of labor imbalances for businesses and governments and offer further remedies to help mitigate them.
Demographic risk is one of the most insidious of all megatrends threatening the global economy, but its impact throughout the world is neither simultaneous nor uniform.
For our research, we performed simulations on 25 major economies to quantify the extent of labor shortages and surpluses for 2020 and 2030. Overall, by 2020, many countries will still be experiencing a surplus. By 2030, however, this surplus will have turned into a massive shortfall.
These are some of the crippling labor shortages and chronic labor surpluses that the world faces:
To quantify these shortages and surpluses, we calculated annual labor supply and demand until 2030. Let’s look first at labor supply.
The Labor Supply Forecast. We found that the labor supply is shrinking in Germany, Poland, Russia, and Japan—and will continue to shrink until 2020. From 2020 to 2030, workforce contraction will accelerate. Europe will be severely affected. And for the first time, South Korea and China will experience a decline. Everywhere else, the labor supply will still expand. (See Exhibit 1.) But labor supply is only one side of the coin.
(To understand how we calculated supply and demand, see “The Calculus of Labor Imbalances.”)
The outlook for the 25 economies we studied is mixed, which is not surprising. These regions have diverse economic prospects and varied labor and family policies. The countries currently enjoying strong growth could see that growth halt abruptly if labor supply cannot keep pace with demand. Of the four BRIC countries (Brazil, India, Russia, and China), for instance, only India is safe from an impending shortfall. And countries with labor surpluses and persistently weak or no economic growth face a gloomy outlook as those surpluses threaten to spiral out of control.
The situations in Germany and the U.S. provide an example of the extreme differences in labor supply.
A Shortage in Germany. We calculated that Germany’s labor supply will shrink from roughly 43 million people today to 37 million in 2030. (See Exhibit 2.) We compared this supply picture with two labor-demand scenarios: the first assumes that labor productivity and targeted GDP will continue at the same rate of growth in the future as in the past 10 years; the second assumes that labor productivity and targeted GDP will match that of the past 20 years. In the first, we assumed annual real GDP growth at 1.2 percent and productivity growth at 0.6 percent—that is, the 10-year annual growth rate. In the second, we assumed annual real GDP growth at 1.3 percent and productivity at 0.9 percent (the 20-year annual growth rate from 1993 through 2012). (For a table of average GDP growth and productivity rates for all countries and both periods, see the Appendix, Exhibit 1.)
In each case, the supply of Germany’s labor in 2030 falls short of demand by 8.4 million to 10 million people. The supply and demand curves will intersect—in effect, signaling full employment—as early as 2015. (Economists generally consider full employment to include a base level of natural unemployment, which, for industrialized countries, hovers between 4 and 6 percent historically. But there is no generally accepted percentage; it depends on the economy and on the economist.) In our analysis, we assumed that an unemployment rate lower than 5 percent already indicates a possible shortage of labor. With this built-in level of unemployment, it becomes clear that the talent deficit in Germany is already at hand. Indeed, today there are shortages not only of engineers and IT professionals but also of positions in many other fields.
What will the increasingly dramatic shortage mean? Quite simply, Germany will not achieve its historical GDP growth rates unless it takes action in one or more of the following four ways:
(An additional important strategy—achieving a higher birthrate—would have little effect until 2030, since children born in 2014 will not enter the labor market until 2029 at the earliest. Beyond 2030, however, its impact would be significant.)
A Surplus in the U.S. The surplus in the U.S. presents a starkly contrasting picture. Again, we modeled labor supply and demand using the same two sets of assumptions: GDP and productivity growth rates for the past 10 and 20 years. In each scenario, the supply of labor in 2030 will exceed demand. In the best case (the 20-year demand scenario), supply will exceed demand by at least 7.4 million people. Both scenarios clearly show a diminishing labor surplus until 2030. On the basis of assumptions of the past 20 years, however, the most probable scenario shows a surplus of 4 percent.
The U.S. must find ways to better utilize its workforce as well as increase its economic activity—for example, by repatriating much of the manufacturing it outsourced in recent decades—or it will continue to experience relatively high unemployment. Better workforce utilization would mean improvements in training and education and would also include incentives for individuals and businesses to produce workers with skills and education that better match what is needed. (Many experts today blame poor workforce utilization on a growing mismatch between the educational qualifications of college graduates and labor force needs.) More generally, the U.S. must do a better job of encouraging entrepreneurialism.
In many developed economies, demographic decline—falling birth rates and an aging population—translates into negative labor growth. In the developing world, rapid growth has created an ever-increasing demand for labor. But many emerging economies are also reaching the final phase of their demographic peak. All economies with favorable demographics—developed and developing—risk high unemployment if they fail to push their growth targets. (See “The Economic Effects of Labor Shortages and Surpluses.”)
While a labor surplus invariably attracts more attention, a shortage is just as problematic. The shortage of labor hampers economic growth. It creates wage inflation, leaves vacancies open, and impedes business formation and development. Ultimately, it threatens a country’s competitiveness. A labor surplus is equally unhealthy but for different reasons. On an individual level, long-term unemployment can lead to the attrition of skills, in turn reducing employability. On a national level, high unemployment reduces the tax base and raises the cost of social services and the risk of social instability. In the aggregate, surpluses further reduce an economy’s competitiveness and attractiveness to investors.
China and India. These long-term stars of the emerging world are among the nations with the world’s highest sustained GDP growth for the past 20 years (10.1 percent for China and 6.7 percent for India). Both countries have robust exports, a vast population, a rapidly rising middle class, and infrastructure needs. Both have instituted significant market reforms in recent years to open their economies to foreign trade and competition. But their labor-force trends reveal important differences. (See Exhibit 3.)
China will be hard hit as a consequence of its one-child-per-family policy, which has been in effect since 1979.2 Notes: 2 “ China to ease one-child policy,” Xinhua News Agency, November 15, 2013. This policy has helped make the world’s most populous country also its most rapidly aging. Recent proposals to ease this policy, if implemented, will have only limited impact over the next decade.
By contrast, India’s demand for labor will not exceed supply until 2030, giving the country enormous headroom for further growth—assuming its existing workforce is utilized more effectively. India’s supply-demand balance will also depend on how much of the workforce transitions from the nation’s huge “shadow” economy into its formal economy. (See “What the Official Unemployment Numbers Don’t Show.”)
In some cases, the surpluses we calculated exceed official unemployment rates. Because of their political and economic sensitivity, unemployment rates are sometimes defined by governments in ways that can minimize unemployment’s actual magnitude. Inevitably, there are inconsistencies in these definitions from country to country, which means comparisons might not always be reliable. For that reason, we cross-checked official data against a variety of sources whenever possible.
Of the six unemployment measures used by the U.S. Department of Labor, the one commonly reported in the press is U-3. The broadest unemployment measure (U-6) has hovered around 14 percent since late 2012 and mid-2013, versus the 8 percent rate that is generally reported.1
On the flip side are people employed in the “shadow” economy—not only the black market but also legitimate, cash-only businesses with job numbers that don’t show up in official labor surveys. India may be the most dramatic example of this phenomenon, with its numerous small businesses that employ fewer than ten people. A 2010 World Bank study calculated that India’s shadow economy represents roughly one-fifth of the nation’s official GDP, and the Indian government’s 2013 economic survey estimates that such informal employment accounts for as much as 85 percent of overall employment.2

Which of the two countries commands the leading position in the East will depend largely on how policymakers address fundamental questions relating to the labor market.
Australia and Japan. Thanks to its commodity-rich economy, Australia was able to continue growing through the end of the first decade of the twenty-first century—successfully insulating itself from the global downturn. If it continues on this trajectory and maintains its GDP growth of above 3.0 percent, Australia will likely experience a severe labor shortage by 2030. By contrast, Japan’s outlook is for continued slow—potentially negative—growth. However, with an aging workforce, Japan’s supply-demand gap will narrow. If growth picks up to 10- or 20-year GDP and productivity levels, Japan’s labor surplus may reverse to a shortage through 2030. (See “Japan’s Never-Ending Workforce Challenges.”)
Around 1995, Japan saw its working-age population begin to decline. By the start of the current millennium, even with a slowing economy, Japan faced the same problem that Germany (along with many mature economies) faces today and that South Korea (and other economies) will face tomorrow: a shrinking workforce.
A look at the six key drivers of labor supply and demand and their impact on Japan in recent decades illuminates the challenges inherent in addressing workforce imbalances:
Has a labor shortage constrained Japan’s economic growth? There is no doubt that these six factors have contributed significantly to Japan’s decline over the last decades—from around 4 percent annual average GDP growth in the 1980s to less than 1 percent from 2003 through 2012.
To be sure, activating these levers can be difficult, given the complex dynamics of policy, politics, and individual choice. But these are all direct means of alleviating labor force shortages, and countries must be as proactive as they can be. If countries such as Germany and South Korea make no attempt to activate these six levers, they might experience the same economic decline that Japan has.

South Korea and Russia. Of all the Asian economies analyzed, South Korea faces the most significant labor shortages. If its 20-year historic GDP and productivity averages persist, it will suffer the second-greatest shortfall of the 25 countries. Due to rapidly aging society, South Korea is expected to have one of the oldest populations of the OECD countries by 2040 (second only to Japan), and it has little latitude left to address this shortfall by increasing the number of working hours per employee.3 Notes: 3 According to “ 2013 Statistics on the Aged,” from Statistics Korea, an official government website, retrieved on December 3, 2013, nearly one-third of the population will be 65 or over. According to ILO and World Development Indicators by The World Bank, South Korea reached 2,090 hours per worker in 2011. Of the 25 economies, it has the largest number of employees working more than 2,000 hours per year.
Similarly, Russia faces significant shortfalls in the 10-year scenario—a more realistic picture than the 20-year scenario. Russia had negative GDP growth in the 1990s. It is not likely that the country will have the same growth in the future as in the 20-year scenario—which considers all years from 1993 to 2000, considerably bringing down the overall average.
Italy and the UK. The labor picture is very mixed throughout Europe, and Italy and the UK offer two good examples. (See Exhibit 4.) These nations have comparably sized working populations: 25 million economically active 15- to 64-year-olds in Italy (out of a total of 40 million in that age range) and 31 million in the UK (out of a total of 41 million in that age range). Both countries—Italy in particular—suffer from high unemployment.
Longer term, Italy and the UK face completely different workforce challenges. Italy’s demographic woes—the country is Europe’s most rapidly aging society—translate into a labor shortage by 2030 in the 10- and 20-year growth scenarios.4 Notes: 4 Figures for the UK and Italy are from World Population Prospect: The 2010 Revision, UN Population Division, 2010. The UK, however, grapples with chronic unemployment as a result of an expanding labor supply and inadequate economic growth.
France and Spain. France’s demographic structure is much healthier than neighboring Germany’s. Yet depending on its GDP and productivity growth, France may well suffer relatively high unemployment over a longer period. Much of its unemployment troubles stem from stringent employee protections that stifle job creation and workforce flexibility. In the 20-year growth scenario, however, even France faces a talent scarcity by 2030.
Conversely, Spain was among the hardest hit by the global financial and euro crisis. Next to South Africa and Saudi Arabia, it suffers the highest relative labor surplus of the 25 economies we analyzed. Using either of the two growth scenarios, Spain’s labor surplus will remain high through 2020.
Switzerland and Poland. While Switzerland’s demographic situation is frequently overshadowed by that of its European peers, the country nonetheless faces severe shortages. Today, its own economically active population cannot match the demand for workers. In 2012, 263,000 workers from neighboring countries were commuting to Switzerland daily to work.5 Notes: 5 Data for 2012 in the Cross-border Commuter Statistics (CCS) comes from the Swiss Federal Statistical Office. By 2030, this number could be significantly higher as a result of the growing workforce gap.
Poland’s story stands out because it was the only EU country to avoid recession during the 2009 downturn. It has benefited from more than 20 years of economic liberalization and, since 2004, membership in the European Union. If GDP and labor productivity growth rates remain at five- or ten-year levels, however, Poland may face a severe labor shortage of up to 24 percent by 2030.
Latin America and South Africa. In these emerging economies, rapid economic growth and policy changes, combined with underlying social and infrastructure challenges, present wide-ranging prospects even within the same country. (See Exhibit 5.)
In Argentina, for example, shifting monetary and fiscal policies have put the country through numerous economic ups and downs since the global financial crisis. An influx of immigrants (Europeans fleeing the euro crisis and returning South Americans), along with a young population, threatens to keep unemployment high through 2020 and 2030. (The ten-year growth scenario, however, presents a different picture, since it includes the country’s recovery following a deep economic crisis that began in 2001.)
By contrast, Brazil faces surging shortages, regardless of scenario. The world’s seventh-largest economy was among the first emerging markets to recover from the global financial crisis. Slowing population growth and an aging population are rapidly altering the nation’s demographic makeup. Much of Brazil’s working-age population is underqualified as a result of gaps in the nation’s education system.
And while Mexico’s supply-and-demand gaps are not nearly as wide as those of other Latin American economies, our projections show different outcomes for Mexico over different periods. Because of the nation’s dependency on exports, outdated labor laws, high poverty rates, and education system in need of improvement, labor surpluses are likely through 2020. After 2030, however, shortfalls are probable.
South Africa’s growth as an emerging economy has masked serious workforce challenges. Its protracted double-digit relative labor surplus puts it in the ranks of the highest-unemployment economies through 2020. By 2030, based on the 20-year GDP and labor-productivity growth-rate assumptions, it will be the highest-unemployment economy with the greatest surplus (39.2 percent). The country’s 50 percent poverty rate, infrastructure needs, and large deficits represent significant challenges to growth.
In 2020, we see a mixed labor picture. By 2030, however, most countries will face labor shortages. (See Exhibit 6.) Surpluses of between 0 and 5 percent represent de facto shortages (natural unemployment), in which job openings are already difficult to fill.
What do these shortages and surpluses mean to the world economy? What aggregate impact could they have by the year 2030? The answer can be represented by an equation. The impact that comes from a surplus (what a country could produce if it created enough jobs) plus the impact that comes from a shortage (what a country cannot produce because it does not have enough people to fill the available jobs or does not have the required productivity increase) equal total impact—that is, the total potential economic loss that results from the supply-and-demand mismatch.
We begin by taking the labor gap figure for each country—the number of people constituting the shortage or surplus—and multiplying it by the labor productivity (per worker) average. (We ran calculations using the two sets of averages but this report is based on the 20-year assumptions—presumably the most reliable numbers since they cover the longest term.) The resulting number is the dollar value of GDP not created. Adding all of the country results together, we get the total GDP not created as a result of these labor gaps. In the 20-year productivity scenario, we calculated $10 trillion of lost GDP. Addressing labor force imbalances will clearly have a huge economic effect.
Our aim here, however, is not to dissect the underlying causes of workforce imbalances or to elaborate on recommendations. It is simply to quantify these imbalances today and over the coming years and to draw attention to their severity and imminence. Their effects on individual countries, as well as on regional economies and the global economy, cannot be taken lightly.
Clearly there is no one solution, neither for the specific problems of labor shortage and labor surplus nor for the particular type of economy, whether developed or developing. We believe that each situation calls for a focused set of interventions. Many cases will require activating a combination of levers. (See “Closing the Gap: How Germany Could Mitigate Its Labor Shortage.”)
To further illustrate the magnitude of global labor-force risks, let’s consider what it would take for Germany to close the serious labor gap we project it will have by 2030. (See the exhibit below.)
Assuming a target GDP growth rate of 1.3 percent (the 20-year average annual rate), Germany would need to do all of the following to close the gap:
Calculating these measures is easy; putting them into action is generally not.
Mitigating a Labor Shortage. A shortfall in available labor renders economies unable to meet their growth targets. To tackle the problem—and sustain economic growth—four fundamental actions can be taken:
Minimizing a Labor Surplus. A surplus means unemployment. The most straightforward solution for unemployment is, of course, economic growth. There are many possible strategies for boosting GDP growth. From a workforce perspective, however, a labor surplus can be reduced by better utilizing the existing workforce. The following are some of the approaches that are available:
These general suggestions are only a start. There are many more strategies for reducing unemployment through growth, workforce levers, or a combination of the two. Whether by legislation and regulation, economic incentives, or even social pressures, solutions to labor force imbalances will need to come from many quarters—government, business, educational and other institutions, and civil society. The first step in solving imbalances, though, is fostering awareness about the magnitude and the imminence of the problem.
For this report, we examined aggregate national workforces, identifying major global and local imbalances. In subsequent reports, we will break down these numbers by education levels and job families, which will further emphasize the severity of global labor problems. A country may appear to have a perfect overall balance of supply and demand, but after decomposing the numbers, we might find that it, in fact, has a surplus of 1 million people with a primary education but a shortfall of 1 million with a secondary education. This kind of de-averaging reveals the crucial challenge ahead for governments and businesses. Both will need far more sophisticated tools to analyze supply and demand, issues that we will explore in our forthcoming reports.
