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.

News Explainer: The Economic Crisis in Sri Lanka
Sri Lanka is currently in an economic crisis with over $50 billion in debt and consumer inflation at 39%. So how did they get here?
Explained: the Economic Crisis in Sri Lanka
Sri Lanka is currently in an economic and political crisis of mass proportions, recently culminating in a default on its debt payments. The country is also nearly at empty on their foreign currency reserves, decreasing the ability to purchase imports and driving up domestic prices for goods.
There are several reasons for this crisis and the economic turmoil has sparked mass protests and violence across the country. This visual breaks down some of the elements that led to Sri Lanka’s current situation.
A Timeline of Events
The ongoing problems in Sri Lanka have bubbled up after years of economic mismanagement. Here’s a brief timeline looking at just some of the recent factors.
In 2009, a decades-long civil war in the country ended and the government’s focus turned inward towards domestic production. However, a stress on local production and sales, instead of exports, increased the reliance on foreign goods.
Unprompted cuts were introduced on income tax in 2019, leading to significant losses in government revenue, draining an already cash-strapped country.
The COVID-19 pandemic hit the world causing border closures globally and stifling one of Sri Lanka’s most lucrative industries. Prior to the pandemic, in 2018, tourism contributed nearly 5% of the country’s GDP and generated over 388,000 jobs. In 2020, tourism’s share of GDP had dropped to 0.8%, with over 40,000 jobs lost to that point.
Recently, the Sri Lankan government introduced a ban on foreign-made chemical fertilizers. The ban was meant to counter the depletion of the country’s foreign currency reserves.
However, with only local, organic fertilizers available to farmers, a massive crop failure occurred and Sri Lankans were subsequently forced to rely even more heavily on imports, further depleting reserves.
In early April this year, massive protests calling for President Gotabaya Rajapaksa’s resignation, sparked in Sri Lanka’s capital city, Colombo.
In May, pro-government supporters brutally attacked protesters. Subsequently, Prime Minister Mahinda Rajapaksa, brother of President Rajapaksa, stepped down and was replaced with former PM, Ranil Wickremesinghe.
Recently, the government approved a four-day work week to allow citizens an extra day to grow food, as prices continue to shoot up. Food inflation increased over 57% in May.
Additionally, the increasing prices on grain caused by the war in Ukraine and rising fuel prices globally have played into an already dire situation in Sri Lanka.
The Key Information
“Our economy has completely collapsed.”
Prime minister Ranil Wickremesinghe to Parliament last week.
One of the main causes of the economic crisis in Sri Lanka is the reliance on imports and the amount spent on them. Let’s take a look at the numbers:
- 2021 total imports = $20.6 billion USD
- 2022 total imports (to March) = $5.7 billion USD
In contrast, the most recent reported foreign currency reserve levels in the country were at an abysmal $50 million, having plummeted an astounding 99%, from $7.6 billion in 2019.
Some of the top imports in 2021, according to the country’s central bank were:
- Refined petroleum = $2.8 billion
- Textiles = $3.1 billion
- Chemical products = $1.1 billion
- Food & beverage = $1.7 billion
Of course, without the cash to purchase these goods from abroad, Sri Lankans face an increasingly drastic situation.
Additionally, the debt Sri Lanka has incurred is huge, further hampering their ability to boost their reserves. Recently, they defaulted on a $78 million loan from international creditors, and in total, they’ve borrowed $50.7 billion.
The largest source of their debt is by far due to market borrowings, followed closely by loans taken from the Asian Development Bank, China, and Japan, among others.
What it Means
Sri Lanka is home to more than 22 million people who are rapidly losing the ability to purchase everyday goods. Consumer inflation reached 39% at the end of May.
Due to power outages meant to save energy and fuel, schools are currently shuttered and children have nowhere to go during the day. Protesters calling for the president’s resignation have been camped in the capital for months, facing tear gas from police and backlash from president Rajapaksa’s supporters, but many have also responded violently to pushback.
India and China have agreed to send help to the country and the the International Monetary Fund recently arrived in the country to discuss a bailout. Additionally, the government has sent ministers to Russia to discuss a deal for discounted oil imports.
A Foreshadowing for Low Income Countries
Governments need foreign currency in order to purchase goods from abroad. Without the ability to purchase or borrow foreign currency, the Sri Lankan government cannot buy desperately needed imports, including food staples and fuel, causing domestic prices to rise.
Furthermore, defaults on loan payments discourage foreign direct investment and devalue the national currency, making future borrowing more difficult.
What’s happening in Sri Lanka may be an ominous preview of what’s to come in other low and middle-income countries, as the risk of debt distress continues to rise globally.
The Debt Service Suspension Initiative (DSSI) was implemented by G20 countries, suspending nearly $13 billion in debt from the start of the pandemic until late 2021.
Some DSSI and LIC countries facing a high risk of debt distress include Zambia, Ethiopia, and Tajikistan, to name a few.
Going forward, Sri Lanka’s next steps in managing this situation will either serve as a useful example for other countries at risk or a warning worth heeding.

Interest Rate Hikes vs. Inflation Rate, by Country
Inflation rates are reaching multi-decade highs in some countries. How aggressive have central banks been with interest rate hikes?
Interest Rate Hikes vs. Inflation Rate, by Country
Imagine today’s high inflation like a car speeding down a hill. In order to slow it down, you need to hit the brakes. In this case, the “brakes” are interest rate hikes intended to slow spending. However, some central banks are hitting the brakes faster than others.
This graphic uses data from central banks and government websites to show how policy interest rates and inflation rates have changed since the start of the year. It was inspired by a chart created by Macrobond.
How Do Interest Rate Hikes Combat Inflation?
To understand how interest rates influence inflation, we need to understand how inflation works. Inflation is the result of too much money chasing too few goods. Over the last several months, this has occurred amid a surge in demand and supply chain disruptions worsened by Russia’s invasion of Ukraine.
In an effort to combat inflation, central banks will raise their policy rate. This is the rate they charge commercial banks for loans or pay commercial banks for deposits. Commercial banks pass on a portion of these higher rates to their customers, which reduces the purchasing power of businesses and consumers. For example, it becomes more expensive to borrow money for a house or car.
Ultimately, interest rate hikes act to slow spending and encourage saving. This motivates companies to increase prices at a slower rate, or lower prices, to stimulate demand.
Rising Interest Rates and Inflation
With inflation rates hitting multi-decade highs in some countries, many central banks have announced interest rate hikes. Below, we show how the inflation rate and policy interest rate have changed for select countries and regions since January 2022. The jurisdictions are ordered from highest to lowest current inflation rate.
|Jurisdiction||Jan 2022 Inflation||May 2022 Inflation||Jan 2022 Policy Rate||Jun 2022 Policy Rate|
The Euro area has 3 policy rates; the data above represents the main refinancing operations rate. Inflation data is as of May 2022 except for New Zealand and Australia, where the latest quarterly data is as of March 2022.
The U.S. Federal Reserve has been the most aggressive with its interest rate hikes. It has raised its policy rate by 1.5% since January, with half of that increase occurring at the June 2022 meeting. Jerome Powell, the Federal Reserve chair, said the committee would like to “do a little more front-end loading” to bring policy rates to normal levels. The action comes as the U.S. faces its highest inflation rate in 40 years.
On the other hand, the European Union is experiencing inflation of 8.1% but has not yet raised its policy rate. The European Central Bank has, however, provided clear forward guidance. It intends to raise rates by 0.25% in July, by a possibly larger increment in September, and with gradual but sustained increases thereafter. Clear forward guidance is intended to help people make spending and investment decisions, and avoid surprises that could disrupt markets.
Pacing Interest Rate Hikes
Raising interest rates is a fine balancing act. If central banks raise rates too quickly, it’s like slamming the brakes on that car speeding downhill: the economy could come to a standstill. This occurred in the U.S. in the 1980’s when the Federal Reserve, led by Chair Paul Volcker, raised the policy rate to 20%. The economy went into a recession, though the aggressive monetary policy did eventually tame double digit inflation.
However, if rates are raised too slowly, inflation could gather enough momentum that it becomes difficult to stop. The longer high price increases linger, the more future inflation expectations build. This can result in people buying more in anticipation of prices rising further, perpetuating high demand.
“There’s always a risk of going too far or not going far enough, and it’s going to be a very difficult judgment to make.” — Jerome Powell, U.S. Federal Reserve Chair
It’s worth noting that while central banks can influence demand through policy rates, this is only one side of the equation. Inflation is also being caused by supply chain issues, a problem that is more or less outside of the control of central banks.
