Animation: U.S. Population Pyramid From 1980-2050

Published

It’s no secret that an aging population will be the source of major demographic challenges in the coming years.

In 1975, the median age in the United States was just 28 years old. However, it’s been rising fast as the Baby Boomers age, and it’s expected to break the 40 year mark by 2030.

This shift is so fundamental that its ripples will be felt in almost every area imaginable. How we manage this change will have implications on the economy, culture, and politics – and it will almost certainly affect our personal wealth and investments, as well.

Visualizing Age in the U.S.

We’ve previously compared the population pyramids of China and India, but today we’re going to key in on the U.S. using a similar type of animation.

Below is an animated population pyramid that shows how the U.S. population has been shifting, including projections up until 2050 based on data from the U.S. Census Bureau and World Bank.

By 2050, the U.S. population will close in on 400 million people.

As with most demographic data, viewing changes in the composition of this population through a visual lens helps to provide perspective.

Aging Population

One of the biggest differences in this particular chart can be seen in the 65+ year region. In the 1980s, only a small portion of the population fits there – but by the end, it’s becoming quite crowded.

In more numerical terms – the number of Americans aged 65+ is projected to jump from 46 million today to over 98 million by 2060, and the 65+ age group’s share of the total population will rise to nearly 24%. This is mainly a function of a big generation (Baby Boomers) hitting their later years, and improved life expectancy and healthcare.

According to the Population Reference Bureau, aging Baby Boomers could mean a massive 75% increase in number of Americans requiring nursing home care, from 1.3 million in 2010 to 2.3 million in 2030.

Social Security and Medicare expenditures will also increase from 8% to 12% of GDP by 2050.

Fewer Babies

Another factor in the population equation is also lower fertility rates.

U.S. Fertility Rate (births per woman)
Fertility Rates in the U.S.

In the United States, the fertility rates that led to the Baby Boomer generation (born 1946-1964) have been long-gone for many decades now.

Lately, fertility has been hovering closer to 1.8 births per woman.

For reference, the replacement fertility rate is about 2.1 – meaning that without taking into account net immigration, each new generation will be smaller than the last. Unless something changes here (or with immigration policy), a more mature population will increasingly become the norm for the country.

*Inflation rates based on the latest available data.

As price pressures mount, 33 central banks tracked by the Bank of International Settlements (out of a total of 38) have raised interest rates this year. These coordinated rate hikes are the largest in two decades, representing an end to an era of rock-bottom interest rates.

Going into 2023, central banks could continue this shift towards hawkish policies as inflation remains aggressively high.

The Role of Energy Prices

Driven by the war in Ukraine, energy inflation is pushing up the cost of living around the world.

Since October 2020, an index of global energy prices—made up of crude oil, natural gas, coal, and propane—has increased drastically.

Double-Digit Inflation

Compared to the 2021 average, natural gas prices in Europe are up sixfold. Real European household electricity prices are up 78% and gas prices have climbed even more, at 144% compared to 20-year averages.

Amid global competition for liquefied natural gas supplies, price pressures are likely to stay high, even though they have fallen recently. Other harmful consequences of the energy shock include price volatility, economic strain, and energy shortages.

“The world is in the midst of the first truly global energy crisis, with impacts that will be felt for years to come”.

-Fatih Birol, executive director of the IEA

Double-Digit Inflation: Will it Last?

If history is an example, taming rising prices could take at least a few years yet.

Take the sky-high inflation of the 1980s. Italy, which managed to combat inflation faster than most countries, brought down inflation from 22% in 1980 to 4% in 1986.

If global inflation rates, which hover around 9.8% in 2022, were to follow this course, it would take at least until 2025 for levels to reach the 2% target.

It’s worth noting that inflation was also highly volatile over this decade. Consider how inflation fell across much of the rich world by 1981 but shot up again in 1987 amid higher energy prices. Federal Reserve chair Jerome Powell spoke to the volatility of inflation at their November meeting, indicating that high inflation has a chance of following a period of low inflation.

While the Federal Reserve projects U.S. inflation to fall closer to its 2% target by 2024, the road ahead could still get a lot bumpier between now and then.

Visualized: The Many Shapes of Bacteria

We introduce the visual diversity of bacteria and illustrate how they are categorized by appearance—from a single cell to an entire colony.

Invisible Diversity: The Many Shapes of Bacteria

Bacteria are amazing.

They were the first form of life to appear on Earth almost 3.8 billion years ago.

They make up the second most abundant lifeform, only outweighed by plants.

And most interesting of all: they exist in practically every environment on our planet, including areas where no other lifeforms can survive. As a result, bacteria exhibit a wide variety of appearances, behaviors, and applications similar to the lifeforms we see in our everyday lives.

The incredible diversity of bacteria goes underappreciated simply because they are invisible to the naked eye. Here, we illustrate how researchers classify these creatures on the basis of appearance, giving you a glimpse into this microscopic world.

A Life of Culture

Though bacteria may look similar to other microorganisms like fungi or plankton, they are entirely unique on a microscopic and genetic level.

Bacteria make up one of the three main domains of life. All life shares its earliest ancestor with this group of microbes, alongside two other domains: the Archaea and the Eukarya.

Archaea are very similar to bacteria, but have different contents making up their cell walls.

Eukarya largely consists of complex, multicellular life, like fungi, plants, and animals. Bacteria are similar to its single-celled members because all bacteria are also unicellular. However, while all Eukarya have nuclear membranes that store genetic material, bacteria do not.

Bacteria have their genetic material free-floating within their cellular bodies. This impacts how their genes are encoded, how proteins are synthesized, and how they reproduce. For example, bacteria do not reproduce sexually. Instead, they reproduce on their own.

Bacteria undergo a process called binary fission, where any one cell divides into two identical cells, and so on. Fission occurs quickly. In minutes, populations can double rapidly, eventually forming a community of genetically identical microbes called a colony.

Colonies can be visible to the human eye and can take on a variety of different shapes, textures, sizes, colors, and behaviors. You might be familiar with some of these:

Superstars of a Tiny World

The following are some interesting bacterial species, some of which you may be familiar with:

Epulopiscium spp

This species is unusually large, ranging from 200-700 micrometers in length. They are also incredible picky, living only within the guts of sturgeon, a type of large fish.

Deinococcus radiodurans

D. radiodurans is a coccus-shaped species that can withstand 1,500 times the dose of radiation that a human can.

Escherichia coli

Despite being known famously for poisoning food and agriculture spaces from time to time, not all E.coli species are dangerous.

Desulforudis audaxviator

Down in the depths of a South African gold mine, this species thrives without oxygen, sunlight, or friends—it is the only living species in its ecosystem. It survives eating minerals in the surrounding rock.

Helicobacter pylori

Known for causing stomach ulcers, this spiral-shaped species has also been associated with many cancers that impact the lymphoid tissue.

Planococcus halocryophillus

Most living things cease to survive in cold temperatures, but P. halocryophillus thrives in permafrost in the High Arctic where temperatures can drop below -25°C/-12°F.

‘Bact’ to the Future

Despite their microscopic size, the contributions bacteria make to our daily lives are enormous. Researchers everyday are using them to study new environments, create new drug therapies, and even build new materials.

Scientists can profile the diversity of species living in a habitat by extracting DNA from an environmental sample. Known as metagenomics, this field of genetics commonly studies bacterial populations.

In oxygen-free habitats, bacteria continuously find alternative sources of energy. Some have even evolved to eat plastic or metal that have been discarded in the ocean.

The healthcare industry uses bacteria to help create antibiotics, vaccines, and other metabolic products. They also play a major role in a new line of self-building materials, which include “self-healing” concrete and “living bricks”.

Those are just a few of the many examples in which bacteria impact our daily lives. Although they are invisible, without them, our world would undoubtedly look like a much different place.
