A High Level Look at Satellites

View the full-size version of the first visualization to see in full detail.

Satellites rarely get much attention, but they’re the hubs that keep our modern world connected. Just how many satellites are orbiting around Earth? Who’s launching them? And, what exactly are they doing up there anyway? These are good questions. Let’s dig in.

Today’s visualization comes to us from Carey Spies, and while it is based on older data, it provides a useful breakdown of the types of satellites that orbit the Earth.

There are now nearly 1,500 satellites in orbit in 2017, and if SpaceX’s plans for a 4,425-satellite communications network come to fruition, our planet’s exosphere will become even more crowded.

What do satellites actually do?

Satellites are launched into space for a number of reasons.

They do everything from military reconnaissance to keeping our GPS systems working properly. The truly global scope of telecommunications wouldn’t be possible without our expansive network of orbiting satellites. For example, O3b Networks’ 12 satellites provide broadband internet service to emerging markets.

Types of Satellites

Who’s launching satellites?

The United States, with nearly 600 operating satellites, has clearly won the space race in this sense. That said, everyone from Azerbaijan to Vietnam now has equipment in orbit, and the list keeps growing.

The change over time, seen in this interactive map, shows that now practically everyone is in the game:

Launching rockets used to be the sole domain of nations, but the privatization of spaceflight has dramatically increased the number of commercial satellites in orbit. Iridium Communications, for example, has a constellation of 70+ operational satellites.

Anxiety in the Exosphere

Operating satellites are only one part of the equation. Sputnik I was launched into space nearly 60 years ago, and as one might guess, a lot of obsolete and dead equipment has built up over that time. The United States Space Surveillance Network estimates that there are 21,000 objects larger than 10cm orbiting the Earth. An increase in “space junk” could have major implications, as even tiny objects can cause severe damage to equipment.

We must cooperate now to guarantee economically vital spaceflight.

– Brigitte Zypries, German Federal Minister for Economic Affairs and Energy

Another looming issue is the potential weaponization of space. Until now, nations have operated under the “gentlemen’s agreement” that nothing launched into space should be weaponized, but the U.S., China, and Russia have all been accused of taking steps towards putting destructive objects into orbit. Beyond the obvious implications of conflict in space, damaged satellites would also exacerbate the aforementioned “space junk” problem.

What’s on the Horizon

While companies like SpaceX are looking for ways to reduce the overall cost of launching rockets into space, other innovations may also make it easier than ever to put structures into orbit. The Archinaut Program – which received $20 million in funding from NASA – is looking at ways to manufacture and assemble structures in space.

One thing is for certain; space is about to get a whole lot more crowded.

Visualizing the Decline of Confidence in American Institutions

Americans rely on several institutions for their services and safety—but how has their confidence in institutions changed since 1975?

Published

on

Every day, the public relies on a number of major institutions for services and safety. From banks and governments, to media and the military—these institutions play an important role in shaping life as we know it.

Yet, today’s interactive data visualization from Overflow Data shows that America’s confidence in institutions has drastically waned. The data relies on the General Social Survey (GSS) to provide a 40-year overview of how sentiment has changed with respect to 13 different institutions.

Select an institution from the drop-down menu below to see how confidence has changed over time

The Erosion of Confidence

Overall, confidence in most institutions has eroded. Americans find it especially hard to trust their government: the “great deal of confidence” metrics for Congress, the Supreme Court, and the Executive Branch were low to begin with, and have declined further since 1975.

That said, the biggest overall drop belongs to the press, which saw 50% of surveyed Americans saying they have “hardly any confidence” in it in 2016. This is nearly a three-fold increase from 1975, when that number was just 19%. Of course, with the rise of fake news in more recent years, the erosion of confidence in media doesn’t seem to be slowing down.

Here’s a look at the two extremes of sentiment regarding the studied institutions, showing how the opposite measures of “hardly any confidence” and a “great deal of confidence” have changed since 1975:

Banks and financial institutions have also suffered a bad rep in the public eye. Their “great deal of confidence” metric has dropped sharply from 32.3% to 14.1% in four decades.

One major exception is the military, which emerges as the most trusted institution. Americans’ faith in the military has also shown the most improvement, with a 17.1 p.p increase in a “great deal of confidence” since 1975.

The Split Widens Further

While measuring public confidence in institutions can be subjective, it provides an understanding of where Americans want to see change and reform take place.

All the S&P 500 Women CEOs in One Timeline (2000-2019)

Since the turn of the century, only a meager 5.6% of S&P 500-indexed companies have been led by women. Today’s interactive timeline highlights their tenures.

All the S&P 500 Women CEOs in One Timeline (2000-2019)

Gender equality has made significant strides since the days of Rosie the Riveter. The iconic wartime image continues to symbolize womens’ empowerment in the present—especially in politics and the workforce.

Yet, the higher and further women get in their careers, it’s clear that barriers still remain. Today’s interactive timeline comes to us from Alex Architektonidis of BoardEx, and it tracks all the women chief executive officers (CEOs) of companies listed in the S&P 500 index since the turn of the century.

The kicker? Across the 500 large-cap companies in the index, only 70 women have ever held the position of CEO or similar titles—and only 28 women currently have this status.

Which Industries Have the Most Women CEOs?

The S&P 500 covers approximately 80% of the U.S. equity market by capitalization. Since the index is fluid and regularly updated, women CEOs were selected based on whether their company was listed in the index during their tenure.

Out of all the sectors represented on the timeline, the top categories are retail with 14 women CEOs, engineering and tech with 10 women CEOs, and finance with 9 women CEOs. Food & beverage and utilities are tied with 7 women CEOs each.

Women Leading in the Corporate World

Topping the list is Marion Osher Sandler, the first and longest-serving woman CEO in the United States. She held the title for nearly 27 years at Golden West Financial Corp (from 1980 to 2006), a company she co-founded and grew to $125 billion in assets.

The next person in line for the longest female-led CEO term is Debra A Cafaro, from the healthcare-focused real estate investment trust Ventas Inc. Cafaro has been CEO of Ventas for 20 years, and generated a cumulative total return of 2,559% since 1999—the S&P average for returns over the same time period was only 215%.

Only two women CEOs show up more than twice on the timeline. The first is Meg Cushing Whitman, who served as President/CEO of Ebay from 1998–2008, Chairman/President/CEO of HP Inc. from 2011–2015, and finally as the CEO of Hewlett Packard from 2015 to 2018. In total, Whitman has spent over 16 years as CEO of these S&P 500 companies.

However, Carol Ann Bartz also has an impressive CV, with nearly 17 years as a CEO under her belt. Bartz was the Chairman/President/CEO of the software corporation Autodesk from 1992–2006, and later on at Yahoo from 2009 to 2011.

The most recent addition to this list is Julie Spellman Sweet, who became the CEO of Accenture on September 1st. She was previously the CEO of Accenture’s North American division, and has been crowned on Fortune’s “Most Powerful Women” list from 2016–2018 consecutively. Sweet’s appointment aligns well with Accenture’s corporate diversity targets—the company is aiming for 25% women in managing director roles globally by 2020.

There’s More Work To Be Done

There’s a growing body of evidence that corporate diversity improves a company’s financial bottom line. A recent CNBC analysis shows that in 2019, over half of female CEOs led their company’s stocks to outperform the S&P 500 index, with some even showing quadruple-digit percentage returns (as previously mentioned with Ventas).

Despite womens’ contributions to nearly half the labor force and consistent success as CEOs, they are disproportionately represented higher up the ladder. Women CEOs still lead a meager 5.6% of S&P 500 companies overall—in fact, women CEO appointments are actually slowing down, averaging less than 6% since 2015.

Such stunted growth is setting back equality at the C-suite level drastically. A joint report between the non-profit Lean In and the consulting firm McKinsey & Co. offers some insight into the reasons underlying this disparity:

Since 2015… corporate America has made almost no progress in improving women’s representation. From the outset, fewer women than men are hired at the entry level. And at every subsequent step, the representation of women further declines.
