Visualizing Over A Century of World Fertility

In just 50 years, world fertility rates have been cut in half.

This sea change can be attributed to multiple factors, ranging from medical advances to greater gender equity. But generally speaking, as more women gain an education and enter the workforce, they’re delaying motherhood and often having fewer children in the process.

Today’s interactive data visualization was put together by Bo McCready, the Director of Analytics at KIPP Texas. Using numbers from Our World in Data, it depicts the changes in the world’s fertility rate—the average number of children per woman—spanning from the beginning of the 20th century to present day.

A Demographic Decline

The global fertility rate fell from 5.25 children per woman in 1900, to 2.44 children per woman in 2018. The steepest drop in this shift happened in a single decade, from 1970 to 1980.

In the interactive graphic, you’ll see graphs for 200 different countries and political entities showing their total fertility rate (FTR) over time. Here’s a quick summary of the countries with the highest and lowest FTRs, as of 2017:

Top 10 CountriesFertility rateBottom 10 CountriesFertility Rate
🇳🇪 Niger7.13🇹🇼 Taiwan1.22
🇸🇴 Somalia6.08🇲🇩 Moldova1.23
🇨🇩 Democratic Republic of Congo5.92🇵🇹 Portugal1.24
🇲🇱 Mali5.88🇸🇬 Singapore1.26
🇹🇩 Chad5.75🇵🇱 Poland1.29
🇦🇴 Angola5.55🇬🇷 Greece1.3
🇧🇮 Burundi5.53🇰🇷 South Korea1.33
🇺🇬 Uganda5.41🇭🇰 Hong Kong1.34
🇳🇬 Nigeria5.39🇨🇾 Cyprus1.34
🇬🇲 Gambia5.29🇲🇴 Macao1.36

At a glance, the countries with the highest fertility are all located in Africa, while several Asian countries end up in the lowest fertility list.

The notable decade of decline in average global fertility can be partially traced back to the actions of the demographic giants China and India. In the 1970s, China’s controversial “one child only” policy and India’s state-led sterilization campaigns caused sharp declines in births for both countries. Though they hold over a quarter of the world’s population today, the effects of these government decisions are still being felt.

Population Plateau, or Cliff?

The overall decline in fertility rates isn’t expected to end anytime soon, and it’s even expected to fall past 2.1 children per woman, which is known as the “replacement rate”. Any fertility below this rate signals fewer new babies than parents, leading to an eventual population decline.

Experts predict that world fertility will further drop from 2.5 to 1.9 children per woman by 2100. This means that global population growth will slow down or possibly even go negative.

Africa will continue to be the only region with significant growth—consistent with the generous fertility rates of Nigeria, the DRC, and Angola. In fact, the continent is expected to house 13 of the world’s largest megacities, as its population expands from 1.3 billion to 4.3 billion by 2100.

An Investing Megatrend: How Emerging Wealth is Shaping the Future

Emerging markets are ascending on the global stage and wielding more economic power—and it’s drastically altering the investment landscape.

Published

on

Globalisation is a rising tide that lifts all boats.

In an increasingly connected world, countries are engaging with global markets more than ever before. As a result, global wealth is shifting towards emerging markets. This megatrend—a global trend with sustained impacts—is profoundly influencing everyday life, society, and business.

Shifting Economic Power

Today’s infographic from iShares by BlackRock explains how emerging markets are classified, along with which countries are growing the fastest—and how investors can follow the money.

BlackRock-Emerging-Markets Global Wealth

What Is An Emerging Market?

Every economy goes through five distinct stages of growth:

  1. Traditional Society: Based on primary industries, such as subsistence farming.
  2. The Pre-Conditions of Take-off: Spread of technology creates a more productive agricultural economy.
  3. Take-off: Industrialisation begins, and technological breakthroughs occur.
  4. Drive to Maturity: More complex manufacturing, and large-scale infrastructure investment takes place.
  5. Age of Mass Consumption: Urban society and a tertiary industry dominate, as disposable income grows.
  6. Source

    Emerging markets fall into the transitory stages between ‘Take-off’ and ‘Drive to maturity’ as their economies modernise. Today, such countries offer lots of promise, but also come with a range of challenges:

    • Pro: Greater return potential, growing middle class, increasing consumption
    • Risk: Political instability, lack of infrastructure, lack of market access

    Between 2000–2018, emerging markets’ share of global wealth has more than doubled from 10% to 24%. China is a major player in this transformation.

    China’s Economic Might

    China’s impressive trajectory from agricultural economy to global superpower cannot be ignored. The nation is on track to overtake the U.S. in terms of gross domestic product (GDP, nominal) by the year 2030.

    Year🇨🇳 China GDP🇺🇸 U.S. GDP
    2000$2.2T$12.6T
    2010$6.1T$15T
    2018$10.8T$17.8T
    2020E$16T$20.2T
    2030E$26.5T$23.5T
    2040E$36.6T$28.3T
    2050E$50T$34.1T

    China’s enormous growth has a ripple effect on its GDP composition. A more affluent middle class is buying higher-priced discretionary goods—such as cars and electronics—boosting the country’s domestic consumption.

    Investors must keep an eye out for other emerging markets that are emulating China’s example.

    One Piece Of the Puzzle

    China is just one case study—several other economies are also making strides on the world stage. Each country brings unique advantages, but also barriers to overcome.

    With these major emerging markets in mind, how can investors tap into the global wealth shift?

    Where Are the Opportunities?

    There are several avenues for an investor to play into this megatrend: structural solutions, consumer goods, and international investment.

    Structural solutions

    Emerging markets are increasingly gaining access to technology. Growth in connectivity is closely linked with improved productivity, and many countries are ripe for a surge in online users.

    However, much can still be done to speed up technological adoption, such as boosting 3G/4G network volume and coverage, and lowering the cost of data and smartphones to be more economical.

    By helping solve some of these structural constraints through technological innovation, investors can tap into the economic growth of emerging markets.

    Consumer goods

    As disposable income increases, a sizeable middle class will seek out products that elevate the quality of life. In India, domestic consumption is estimated to hit $6 trillion by 2023—four times its 2018 level.

    The region’s spending will likely be propelled by higher-priced goods, as well as a wider variety of choices across food, transport, and fitness categories.

    Global brands that plan to expand into emerging markets, or companies with a proven track record in these areas, are potential winners for investment.

    International investment

    Last but not least, investors can identify local winners in emerging wealth markets, through active or passive investing.

    An active investment strategy would be to directly buy into individual company stocks, listed on a country’s stock exchange. Meanwhile, a passive investing strategy would be to seek out exchange-traded funds (ETFs) covering specific markets, and/or sectors within emerging markets. Many of these are also listed on major exchanges.

    Diversifying either or both strategies across two or more countries can help mitigate risk. Investors can also choose index funds that broadly encompass all emerging markets.

    As countries climb the economic ladder, the emerging wealth shift continues to gain momentum. By staying attuned to these macro changes, investors may unlock long-term growth from emerging markets.

The Global Inequality Gap, and How It’s Changed Over 200 Years

This visualization shows the global inequality gap — a difference in the standards of living around the world, as well as how it’s changed over 200 years.

Published

on

How the Global Inequality Gap Has Changed In 200 Years

What makes a person healthy, wealthy, and wise? The UN’s Human Development Index (HDI) measures this by one’s life expectancy, average income, and years of education.

However, the value of each metric varies greatly depending on where you live. Today’s data visualization from Max Roser at Our World in Data summarizes five basic dimensions of development across countries—and how our average standards of living have evolved since 1800.

Health: Mortality Rates and Life Expectancy

Child mortality rates and life expectancy at birth are telltale signs of a country’s overall standard of living, as they indicate a population’s ability to access healthcare services.

Iceland stood at the top of these ranks in 2017, with only a 0.21% mortality rate for children under five years old. On the other end of the spectrum, Somalia had the highest child mortality rate of 12.7%—over three times the current global average.

While there’s a stark contrast between the best and worst performing countries, it’s clear that even Somalia has made significant strides since 1800. At that time, the global average child mortality rate was a whopping 43%.

Lower child mortality is also tied to higher life expectancy. In 1800, the average life expectancy was that of today’s millennial—only 29 years old:

Life Expectancy in 1800 by Continent

Today, the global average has shot up to 72.2 years, with areas like Japan exceeding this benchmark by more than a decade.

Education: Mean and Expected Years of Schooling

Education levels are measured in two distinct ways:

  • Mean years: the average number of years a person aged 25+ receives in their lifetime
  • Expected years: the total years a 2-year old child is likely to spend in school

In the 1800s, the mean and expected years of education were both less than a year—only 78 days to be precise. Low attendance rates occurred because children were expected to work during harvests, or contracted long-term illnesses that kept them at home.

Since then, education levels have drastically improved:

 Mean Years of SchoolingExpected Years of schooling 
Global Average8.4 years12.7 years
HighestGermany 🇩🇪: 14.1 yearsAustralia 🇦🇺: 22.9 years
LowestBurkina Faso 🇧🇫: 1.5 yearsSouth Sudan 🇸🇸: 4.9 years

Research shows that investing in education can greatly narrow the inequality gap. Just one additional year of school can:

  • Raise a person’s income by up to 10%
  • Raise average annual GDP growth by 0.37%
  • Reduce the probability of motherhood by 7.3%
  • Reduce the likelihood of child marriage by >5 percentage points
  • Source

    Education has a strong correlation with individual wealth, which cascades into national wealth. Not surprisingly, average income has ballooned significantly in two centuries as well.

    Wealth: Average GDP Per Capita

    Global inequality levels are the most stark when it comes to GDP per capita. While the U.S. stands at $54,225 per person in 2017, resource-rich Qatar brings in more than double this amount—an immense $116,936 per person.

    The global average GDP per capita is $15,469, but inequality heavily skews the bottom end of these values. In the Central African Republic, GDP per capita is only $661 today—similar to the average income two hundred years ago.

    A Virtuous Cycle

    These measures of development clearly feed into one another. Rising life expectancies are an indication of a society’s growing access to healthcare options. Compounded with more years of education, especially for women, this has had a ripple effect on declining fertility rates, contributing to higher per capita incomes.

    People largely agree on what goes into human well-being: life, health, sustenance, prosperity, peace, freedom, safety, knowledge, leisure, happiness… If they have improved over time, that, I submit, is progress.

    Steven Pinker

    As technology accelerates the pace of change across these indicators, will the global inequality gap narrow more, or expand even wider?
