Total fertility rates, which can be defined as the average number of children born to a woman who survives her reproductive years (aged 15-49), have decreased globally by about half since 1960.
This has drastically shaped today’s global economy, but a continued decline could have much more severe long-term consequences. If the world has too many elderly dependents and not enough workers, the burden on economic growth will be difficult to overcome.
Fertility Rates Start to Decline
First, it’s important to address some of the reasons for these falling fertility rates.
In developed nations the introduction of commercially available birth control has played a large role, but this also coincided with several major societal shifts. Changing religious values, the emancipation of women and their increasing participation in the workforce, and higher costs of childcare and education have all factored into declining fertility rates.
Birthrates Wane, Economy Gains
Initially, reduced child dependency rates were actually beneficial to economic growth.
By delaying childbirth, men and women could gain an education before starting a family. This was important in a shifting labor market where smaller, family-run businesses were in decline and a more skilled and specialized labor force was in demand.
Men and women could also choose to start their careers before having families, while paying more in income taxes and enjoying the benefits of a higher disposable income. Increased spending power creates demand, which stimulates job growth – and the economy benefits in the short-term.
A Global Phenomenon
Worldwide fertility rates began to fall substantially in the mid-1960s. While each country has its own underlying causes for this, it is interesting that in developed and developing nations, the downward trend is similar.
Part of this is due to developing countries’ own efforts to rein in their rapidly expanding populations. In China, the One Child Policy was introduced in 1979, however fertility rates had already dropped significantly prior to this. India’s government was also active on this front, sterilizing an estimated 8.3 million people (mostly men) between 1975 and 1977 as a method of population control.
The Age Imbalance
So here we are now, with a global fertility rate of just 2.5 – roughly half of what it was 50 years ago.
Today, 46% of the world’s population lives in countries that are below the average global replacement rate of 2.1 children per woman.
Because these countries (59 to be exact, including BRIC nations Brazil, Russia, and China) are not repopulating quickly enough to sustain their current populations, we are beginning to see a substantial imbalance in the ratio of elderly dependents to working-age people, which will only intensify over the coming decades.
By 2100, the U.N. predicts that nearly 30% of the population will be made of people 60 years and older. Life expectancy also continues to increase steadily, which means those dependents will be living even longer. Between 2000 and 2015 the average global life expectancy at birth increased by around 5 years, reaching an average of 73.8 years for females and 69.1 years for males.
What does this mean for the economy?
As this large aging population exits the workforce, most of the positive trends that were spurred by declining fertility rates will be reversed, and economic growth will face a significant burden.
The global increase of elderly dependent populations will have serious economic consequences. Health care costs for the elderly will strain resources, while the smaller working population will struggle to produce enough income tax revenue to support these rising costs. It’s likely this will cause spending power to decrease, consumerism to decline, job production to slow – and the economy to stagnate.
Immigration has been a source of short-term population sustenance for many nations, including the U.S. and Britain. However, aside from obvious societal tensions associated with this strategy, immigrants are often adults themselves when they relocate, meaning they too will be elderly dependents soon.
Several nations are already experiencing the effects of a large proportion of elderly dependents. Japan, with one-quarter of its total population currently over the age of 65, has been a pioneer in developing technologies, such as robotics, as a solution to ease strained health care resources. Many countries are restructuring health care programs with long-term solutions in mind, while others are attempting to lower the cost of childcare and education.
Visualizing Portfolio Return Expectations, by Country
This graphic shows the gap in portfolio return expectations between investors and advisors around the world, revealing a range of market outlooks.
Visualizing Portfolio Return Expectations, by Country
How do investors’ return expectations differ from those of advisors? How does this expectation gap shift across countries?
Despite 2022 being the worst year for stock markets in over a decade, investors around the world appear confident about the long-term performance of their portfolios. These convictions point towards resilience across global economies, driven by strong labor markets and moderating inflation.
While advisors are optimistic, their expectations are more conservative overall.
This graphic shows the return expectation gap by country between investors and financial professionals in 2023, based on data from Natixis.
Expectation Gap by Country
Below, we show the return expectation gap by country, based on a survey of 8,550 investors and 2,700 financial professionals:
|🇭🇰 Hong Kong SAR||12.4%||7.6%||1.6X|
Investors in the U.S. have the highest long-term annual return expectations, at 15.6%. The U.S. also has the highest expectations gap across countries, with investors’ expectations more than double that of advisors.
Likely influencing investor convictions are the outsized returns seen in the last decade, led by big tech. This year is no exception, as a handful of tech giants are seeing soaring returns, lifting the overall market.
From a broader perspective, the S&P 500 has returned 11.5% on average annually since 1928.
Following next in line were investors in Chile and Mexico with return expectations of 15.1% and 14.7%, respectively. Unlike many global markets, the MSCI Chile Index posted double-digit returns in 2022.
Global financial hub, Singapore, has the lowest expectations gap across countries.
Investors in the UK and Europe, have the most moderate return expectations overall. Confidence has been weighed down by geopolitical tensions, high interest rates, and dismal economic data.
Return Expectations Across Asset Classes
What are the expected returns for different asset classes over the next decade?
A separate report by Vanguard used a quantitative model to forecast returns through to 2033. For U.S. equities, it projects 4.1-6.1% in annualized returns. Global equities are forecast to have 6.4-8.4% returns, outperforming U.S. stocks over the next decade.
Bonds, meanwhile, are forecast to see 3.6-4.6% annualized returns for the U.S. aggregate market, while U.S. Treasuries are projected to average 3.3-4.3% annually.
While it’s impossible to predict the future, we can see a clear expectation gap not only between countries, but between advisors, clients, and other models. Factors such as inflation, interest rates, and the ability for countries to weather economic headwinds will likely have a significant influence on future portfolio returns.
