Histomap: Visualizing the 4,000 Year History of Global Power

Published

on

Imagine creating a timeline of your country’s whole history stretching back to its inception.

It would be no small task, and simply weighing the relative importance of so many great people, technological achievements, and pivotal events would be a tiny miracle in itself.

While that seems like a challenge, imagine going a few steps further. Instead of a timeline for just one country, what about creating a graphical timeline showing the history of the entire world over a 4,000 year time period, all while having no access to computers or the internet?

An All-Encompassing Timeline?

Today’s infographic, created all the way back in 1931 by a man named John B. Sparks, maps the ebb and flow of global power going all the way back to 2,000 B.C. on one coherent timeline.

Histomap, published by Rand McNally in 1931, is an ambitious attempt at fitting a mountain of historical information onto a five-foot-long poster. Although the distribution of power is not quantitively defined on the x-axis, it does provide a rare example of looking at historic civilizations in relative terms. While the Roman Empire takes up a lot of real estate during its Golden Age, for example, we still get a decent look at what was happening in other parts of the world during that period.

The visualization is also effective at showing the ascent and decline of various states, nations, and empires.

Timeline Caveats

Since this chart was created at the beginning of the Great Depression, one does have to consider to what extent Sparks saw history as a zero-sum exercise; a collection of nations battling one another for control over scarce territory and resources.

Crowning a world leader at certain points in history is relatively easy, but divvying up influence or power to everyone across 4,000 years requires some creativity, and likely some guesswork, as well. Some would argue that the lack of hard data makes it impossible to draw these types of conclusions (though there have been other more quantitative approaches.)

Another obvious criticism is that the measures of influence are skewed in favor of Western powers. China’s “seam”, for example, is suspiciously thin throughout the length of the timeline.

Lastly, the histomap refers to various cultural and racial groups using terms that may seem rather dated to today’s viewers.

The Legacy of Histomap

John Spark’s creation is an admirable attempt at making history more approachable and entertaining. Today, we have seemingly limitless access to information, but in the 1930s an all encompassing timeline of history would have been incredibly useful and groundbreaking.

Critiques aside, work like this paved the way for the production of modern data visualizations and charts that help people better understand the world around them today.

Animation: 200 Years of U.S. Immigration As Tree Rings

Since 1830, there have been four major waves of U.S. immigration – and this unique video depicts the influx of immigrants as rings in a tree trunk.

Published

on

If you walk down the streets in the United States, the odds are that one in every four people you’ll see is an immigrant, or was born to immigrant parents.

While those odds might seem high, the truth is nearly everyone in the U.S. hails from someplace else if you look far back enough.

Visualizing U.S. Immigration

Today’s intriguing visualization was created by professors Pedro M. Cruz and John Wihbey from Northeastern University, and it depicts U.S. immigration from 1830 until 2015, as rings in a growing tree trunk.

The researchers turned registered U.S. Census data into an estimate for the total number of immigrants arriving each decade, and then the yearly figures in the visualization. One caveat is that it does not account for the populations of slaves, or indigenous communities.

From the Old to the New World

The pattern of U.S. immigration can be explained in four major waves overall:

U.S. Immigration Waves

The origins of U.S. immigrant populations transform from era to era. Which events influenced each wave?

Frontier Expansion: 1830-1880

  • Cheap farmland and the promise of economic growth in the first Industrial Revolution spurred large-scale immigration from Britain, Germany, and other parts of Central Europe.
  • The Irish Potato Famine from 1845 to 1849 drove many immigrants from Ireland over to the U.S.
  • The 1848 Treaty of Guadalupe ended the Mexican-American war, and extended U.S. citizenship to over 70,000 Mexican residents.

Industrialization: 1880-1915

  • Immigrant mobility increased with the introduction of large steam-powered ships. The expansion of railroads in Europe also made it easier for people to reach oceanic ports.
  • On the other hand, the Chinese Exclusion act in 1882 prohibited Chinese laborers from entry.
  • In 1892, the famous Ellis Island opened; the first federal immigration station provided a gateway for over 12 million people.

The Great Pause: 1915-1965

  • The Immigration Act of 1924 enacted quotas on immigrant numbers, restricting groups from countries in Southern and Eastern Europe, and virtually all immigrants of Asian origin.
  • The Great Depression, and subsequent World Wars also complicated immigration matters as many came to seek refuge in the United States.

Post-1965 Immigration: 1965-Present

  • The Hart-Cellber (Immigration and Naturalization Act) of 1965 overturned all previous quotas based on national origin. Family unification and an increase in skilled labor were two major aims of this act.
  • This decision significantly impacted the U.S. demographic makeup in the following decades, as more immigrants of Latin, Asian, and African descent entered the country.

E Pluribus Unum (From Many, One)

While others have mapped two centuries of immigration before, few have captured its sheer scale and impact quite as strikingly. The researchers explain their reasoning behind this metaphor of tree rings:

This idea lends itself to the representation of history itself, as it shows a sequence of events that have left a mark and shaped the present. If cells leave a mark in the tree, so can incoming immigrants be seen as natural contributors to the growth of a trunk that is the United States.

It’s no wonder that this animation showing U.S. immigration won Gold for the “People, Language, and Identity” and “Most Beautiful” categories at the 2018 Kantar Information is Beautiful Awards.

Global Happiness: Which Countries are the Most (and Least) Happy?

What contributes to happiness? These charts break down global happiness scores – how does your country fare, and how has it changed over ten years?

Published

on

How much happier would you be if were given a 10% raise?

While money can be a crucial indicator of happiness at lower income levels, studies have found that as incomes rise, money becomes a less important part of the overall happiness equation.

In fact, researchers see happiness as a complex measure that involves many variables outside of material wealth, including social support, freedom, and health.

Measuring Global Happiness

Today’s chart uses data from the World Happiness Report 2018 to measure and understand which countries report feeling the most and least happy.

Global Happiness Countries Most and Least Happy

WHAT CONTRIBUTES TO HAPPINESS?

The six key variables used by researchers in this report on global happiness include:

  1. GDP per capita
  2. Healthy life expectancy
  3. Social support
  4. Freedom of choice
  5. Generosity
  6. Perceptions of corruption

While average income and life expectancy definitely carry their weight in explaining happiness levels, what’s more interesting are the Gallup World Poll (GWP) questions about the other, more subjective variables.

  • Social support
    “If you were in trouble, do you have relatives or friends you can count on to help you whenever you need them?”
  • Freedom to make life choices
    “Are you satisfied or dissatisfied with your freedom to choose what you do with your life?”
  • Generosity
    “Have you donated money to a charity in the past month?”
  • Perceptions of corruption
    “Is corruption widespread throughout the government or not?”
    “Is corruption widespread within businesses or not?”

HOW HAPPY IS THE WORLD?

The top tier of happiest countries happen to be Nordic, with Finland, Norway, Denmark, and Iceland making it into the top five. Aside from having a common geographic location, these countries are also well-known for their social safety nets, using a high tax burden to fund government services such as education and healthcare.

A surprising entry near the top of the list might be Costa Rica. It’s the happiest country in the Latin American region, despite persisting income inequality issues. Although it has a lower GDP per capita than other high-ranking entries, the country has more than made up for it through social support; Costa Rica has invested significantly in education and health as a proportion of GDP, and the nation is also known for housing a culture that forms solid social networks of friends, families and neighborhoods.

On the other hand, 18 of the least happy countries are concentrated on the African continent. GDP per capita varies intensely among the bottom countries, and many report a lack of freedom overall. A silver lining is that social support is relatively stable, and there have been steady improvements over time.

Finally, the aftermath of the 2008 financial crisis has had a ripple effect on global happiness. The report demonstrates where the most and fewest advances have been made.

  • Togo
    Happiness is on the upswing, as the West African nation climbs 17 places to demonstrate the most improvement.
  • Venezuela
    Meanwhile, the South American country plummeted even further, in part from socio-political changes and dramatic hyperinflation.

Where does your country fare on this scale?
Changes in Global Happiness Over Time

Eudaimonia [happiness] is the meaning and the purpose of life, the whole aim and end of human existence.
