Interactive Heat Map: Gender Inequality in the World


Here is an interactive heat map showing gender inequality across the world based on each country’s Gender Inequality Index (GII), which according to the number of factors (e.g. maternal mortality rate, the number of seats women hold in government bodies, the labor force participation rate). The lower the GII number, the better gender equality in the country.

According to the map, we can see that gender equality in European countries are higher than countries in other areas as all the top ten are European countries, while the top three are the Netherlands, Sweden, and Denmark. We may be surprised that the U.S. ranks while Canada and U.K. ranks 18 and 34 respectively.

Women in Yemen, Afghanistan, Niger, Saudi Arabia, and Congo are living in the least gender equal society.

Map users can mouseover the countries to see the actual GII in the tooltips and see if you agree with the map. GII is just an index for giving us basic concept about the gender equality in various countries while realistic situation can be various depends on regions (rural areas and cities), how the media treats women, women status in family (e.g. role in parenting and marriage).

This heat map is simple and net enough for showing the GII report with tooltips however, this map can be more informative by providing detailed information for specific countries (e.g. external links to related news, videos, background information of the country).

Currently, there are 1189 billion active users in Facebook per month, though the growing rate is comparatively lower than before, that there are 351 million users in Asia, 276 million users in Europe, 199 million users in US & Canada, and 362 million users in other countries.

It is quite surprising that there are more active users in Asia rather than in US, the origin of Facebook.

In Russia, V Kontakte and Odnoklassniki are still competing to conquer the leader place in the market, and currently V Kontakte is placing the position.

In China, QZone still dominates the Asian market with 623 million users, however, it’s growth is being slowed down by the rising popularity of Weixin recently.

World Map: Gay Marriage in the World

In the past, we have shared several maps about same sex marriage in the United States and world acceptance towards homosexual, and now we have found several maps about the same sex marriage around the world in different countries.

the-gay-marriage-world-mapmap legend for the above world map:gay-marriage-world-map-legend

Since the first legal same sex marriage took place in Amsterdam in 2001, there have been 15 countries (e.g. certain states in US, part of Mexico, Australian Capital territories) legalized it within these 12 years. However, there are still some countries do not accept homosexual (e.g. Sudan, Saudi Arabia, Yemen).

According to below image, it seems that homosexual is more acceptable in Europe that most of the European countries allow same sex marriage, and  same sex unions are allowed.

Heat Map: Average Scores for PISA tests around the world


Today, the score report of the Programme for International Student Assessment (PISA) tests 15-year-olds around the world on reading, math and science is released that the report is released every three years. Washington Post has then created following heat map for presenting the average scores across the world by countries that countries with bluer colors obtain higher scores.

According to the report, regions with highest scores are Shanghai(China), Singapore, and Hong Kong while the Peru gains the lowest score in this test. The United States ranks 25th with an average score of 1476, which is behind most of Western European countries.

However, according to Washington Post, this report is not really fair as urban areas tend to outperform non-urban areas in education, and developing/poorer countries do not have as much public education programs as developed/richer countries.

Map Reviews: 3.5/5 Stars

Clear heat map with map legend for indicating the countries’ colors for various score levels. Here are some suggestions to enrich the map content in interactive format:

  • adding abbreviations for each countries
  • insert infobox for listing the score changing from previous reports

Heat Map: Average Marriage Age across the Globe


According to the data from the UN, it seems that getting married in a later age is a tend across the globe. Here is a heat map shows the average marriage age by country.


According to the map, it reflects the main cause for later marriage age is based on country’s income as people in developed countries (e.g. Western Europe) get marry in a much later age(over 30) than those in developing countries (e.g. Afghanistan in age 20). Women in some developing countries remains getting married in a younger age that 20% of them married by age 18.

According to the data, there are also fewer people getting married, for example in the United States, less than half of American are married and most of babies are born out of wedlock as to married couples.

Though the average marriage is higher and fewer people are married when compare to the past, marriage is still the preferred lifestyle worldwide that 80% of people were married by age 49. People just have to be more patience for forming a new family unit.

This heat map can presents the data in dynamic ways as well. After enabling heat map feature and adding map legend, info boxes can be added to specific regions for enriching the map content with detailed information (e.g.  bar chart in United States, images in Westerna Europe, external links for the UN).

Video Tutorial: Add Markers to HTML5 Map

If you have tried using / are using some mapping software, you should be familiar with the import feature that pinning locations on the map (e.g. a custom Google Map, Open Street Map) by importing data files. This time, we are not going to talk about importing data, but adding markers on a map template.

From the above video, you can see that there are two ways to add markers on a HTML5 map template

  1. manually pin locations on the map
  2. add makers by cities in just few clicks
    here is a sample map for it:

Heat Map: Internet Population in Each Country

Last week, we have shared a world heat map about the most popular websites in the world and internet freedom rankings across the globe. Today, we find another heat map about the internet – internet population in each countries that the map is created by the Information Geographies project at the Oxford Internet Institute.



The map is created based on the data in 2011 that on both country’s internet users and total population from the World Bank. Similar to the previous introduced maps, the size of the countries depend on the total internet population, and the color of the countries represents the percentage of that country’s population that’s online.

Let’s take a look in China, which has a huge number of internet users because of its massive population in general, but the the percentage of citizens on the internet is lower than some European countries.

Still, the total internet population in the map equals to about one-third of Earth’s global population only.

World Map: Cities that Climate Change Will Hit First

Climate changes and global warming are always hot topics in our current discussions. The Washington Post has mapped the findings, which is just published in Nature, a scientific journal, and the two maps can be seen below:

Global Temperature Rise With Carbon Dioxide Mitigation

Global Temperature Rise Without Carbon Dioxide Mitigation

According to the new research from University of Hawaii, global temperatures will exceed historical norms as soon as 2047 that it will happen a lot sooner in some places (e.g. 2020 in Manokwari & Indonesia, 2023 in Kingston & Jamaica, 2047 in Washington).

According to the map legend, cities with dark red dots means they are going to be hit by the global warming very soon. Situation in Europe and the United States seem a bit better, but remember that it is better when comparatively saying.

From the above maps, it seems that we cannot avoid the situation, but we can improve the situation and postpone the hit by reducing the Carbon Dioxide.

Heat Map: Gender Gap in Science across the Globe

A heat map from UNESCO about the gender gap in science around the globe shows relative equality in parts of South America and Central Asia, and relatively higher inequality in countries like India, France, Germany, and Japan, which is quite surprising that women make up less than a third of researchers in some of these world’s science leading countries.

Meanwhile, the map only presents portion of the situation as it does not reflect the women status in science field in countries like United States, Australia, China.

In conclusion, the map does reflect that the world is not all the same.
