Every generation has their own unique approach to money and personal finance.
Millennials, for example, found the journey to adulthood riddled with obstacles such as stagnating wage growth and uncertain economic conditions. These challenges, combined with other generational circumstances, helped to shape the group’s spending habits and attitudes towards money and debt.
Along this journey, Millennials ended up making their fair share of financial mistakes – but interestingly, evidence is now mounting that the next generational cohort (Gen Z) is already learning from their elders.
A New Approach to Money
Today’s infographic comes to us from Rave Reviews and it shows how Gen Z is taking a more pragmatic approach to money.
Gen Z saw some of their older friends take on massive amounts of debt, while also struggling to find well-paying jobs.
As a result, this new generation (born 1997 and onwards) is taking a much more pragmatic approach to the world of personal finance. Gen Zers generally want to secure well-paying and stable jobs, and to grow their savings rather than spending money that they don’t have.
School and Work
For Generation Z, an education is often seen as an end to a financial means. In other words, college is an opportunity to build a set of skills that will be valuable to employers, ensuring a stable career.
That’s why 88% of the first Gen Z grad class in 2017 ended up choosing their majors with job availability in mind.
Recent Gen Z grads are willing to put in the work, as well:
- 75% are willing to relocate to another state for a job offer
- 58% are willing to work evenings and weekends
- 78% have completed an internship or apprenticeship
- 77% earn extra money through freelance work, a part-time job, or an earned allowance
- 35% already own their own business, or are planning to start one in the future
While the Gen Z outlook on school and work is a defining factor in their attitude towards personal finance, how they save and spend money is also making a difference.
Saving and Spending
A whopping 89% of Gen Zers say planning for their financial future makes them feel empowered, while 64% have already begun researching the topic of financial planning.
With dollars and cents on their minds, Gen Z is a more frugal and fiscally responsible group:
- 72% say that cost is most important factor when making a purchase
- 47% use their phones in-store to check prices and ask family or friends for advice
- 66% plan to attend college in-state to save on tuition
As Gen Z enters the professional workforce and starts investing their savings, it will be interesting to see what comes out of this frugal and practical approach to money.
Visualizing Over A Century of Global Fertility
Global fertility has almost halved in the past century. Which countries are most resilient, and which have experienced the most dramatic changes over time?
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 Countries||Fertility rate||Bottom 10 Countries||Fertility Rate|
|🇳🇪 Niger||7.13||🇹🇼 Taiwan||1.22|
|🇸🇴 Somalia||6.08||🇲🇩 Moldova||1.23|
|🇨🇩 Democratic Republic of Congo||5.92||🇵🇹 Portugal||1.24|
|🇲🇱 Mali||5.88||🇸🇬 Singapore||1.26|
|🇹🇩 Chad||5.75||🇵🇱 Poland||1.29|
|🇦🇴 Angola||5.55||🇬🇷 Greece||1.3|
|🇧🇮 Burundi||5.53||🇰🇷 South Korea||1.33|
|🇺🇬 Uganda||5.41||🇭🇰 Hong Kong||1.34|
|🇳🇬 Nigeria||5.39||🇨🇾 Cyprus||1.34|
|🇬🇲 Gambia||5.29||🇲🇴 Macao||1.36|
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.
How Facebook is Using Machine Learning to Map the World Population
Machine learning technology is allowing researchers at Facebook to map the world population in unprecedented detail.
When it comes to knowing where humans around the world actually live, resources come in varying degrees of accuracy and sophistication.
Heavily urbanized and mature economies generally produce a wealth of up-to-date information on population density and granular demographic data. In rural Africa or fast-growing regions in the developing world, tracking methods cannot always keep up, or in some cases may be non-existent.
This is where new maps, produced by researchers at Facebook, come in. Building upon CIESIN’s Gridded Population of the World project, Facebook is using machine learning models on high-resolution satellite imagery to paint a definitive picture of human settlement around the world. Let’s zoom in.
Connecting the Dots
Will all other details stripped away, human settlement can form some interesting patterns. One of the most compelling examples is Egypt, where 95% of the population lives along the Nile River. Below, we can clearly see where people live, and where they don’t.

While it is possible to use a tool like Google Earth to view nearly any location on the globe, the problem is analyzing the imagery at scale. This is where machine learning comes into play.
Finding the People in the Petabytes
High-resolution imagery of the entire globe takes up about 1.5 petabytes of storage, making the task of classifying the data extremely daunting. It’s only very recently that technology was up to the task of correctly identifying buildings within all those images.
To get the results we see today, researchers used process of elimination to discard locations that couldn’t contain a building, then ranked them based on the likelihood they could contain a building.
Facebook identified structures at scale using a process called weakly supervised learning. After training the model using large batches of photos, then checking over the results, Facebook was able to reach a 99.6% labeling accuracy for positive examples.
Why it Matters
An accurate picture of where people live can be a matter of life and death.
For humanitarian agencies working in Africa, effectively distributing aid or vaccinating populations is still a challenge due to the lack of reliable maps and population density information. Researchers hope that these detailed maps will be used to save lives and improve living conditions in developing regions.
For example, Malawi is one of the world’s least urbanized countries, so finding its 19 million citizens is no easy task for people doing humanitarian work there. These maps clearly show where people live and allow organizations to create accurate population density estimates for specific areas.
