Interactive Heat Map: Global Slavery Index 2013

According to the Walk Free Foundation’s Global Dlacery Index 2013, there are nearly 30 million slaves in the world, and almost 60,000 of them are living in the U.S. Here is an interactive world map about the index.

According to the Walk Free, slavery defines as one of the following: human trafficking, forced labor, debt bondage, forced or servile marriage, and the sale or exploitation of children including in armed conflict.

The index ranks 162 countries based on a combined measure of three factors: estimated prevalence of modern slavery by population, a measure of child marriage, and a measure of human trafficking in and out of a country.

The index is mapped into two maps: an interactive heat map & an interactive bubble chart. In the heat map, country with higher slavery prevalence is highlighted with darker red while country with lower slavery prevalence is highlighted with yellow. Map users could see details of each country by mouse clicking the region, or select specific category in the category legends.

In the bubble chart, countries are being plotted on the chart according to their prevalence rank vs human development index/financial service index/corruption index. However, there is no popup box of each bubble for detailed information, and no map legend to indicate various bubble sizes that a bit confuse the map users.

According to the index, 10 countries with the highest prevalence of slavery are Mauritania, Haiti, Pakistan, India, Nepal, Moldova, Benin, Cote d’Ivoire, Gambia, Gabon. Among all the above mentioned countries, India has the most slaves in the world, with an approximated 14 million. 

However, even countries like Iceland, Ireland, and the United Kingdom rank 160 in the index, it does not mean these countries are slavery free, for example, it is estimated there are between 4200 to 4600 “slaves” in the UK.

Map Review: 4.5/5 Stars
We love this map as the map design is simple but informative with clear instruction and indications for users to filter related information in seconds.
There are just minor suggestions to the bubble chart:

  • add a map legend to indicate the bubble sizes
  • insert infobox for each bubble for detailed information

Alternatively, showing data of each country with bubble can be presented on the world map rather than on the chart. Bubble chart map can be easily created in mapping software that you may take following video for reference:

Interactive China Map: How Chinese Travelling Home for Lunar New Year

Rating:

This Friday (31 Jan) is the new year day of Lunar New Year in China, which means it is the beginning of “Chunyun”, a holiday that people travelling home for family gathering. Here is an interactive China map, created by Baidu, for tracking all congestion.

Basically, it is a hell for travelling during this period, and BBC has mentioned that Beijing’s major train stations is know as “the busiest place on the planet” with horrible traffic jams. In order to keep tracking the congestion, Baidu (similar to Google in China) has launched the interactive live map for updating all the trips in each hour. Map users can also search data by date, time, and city. There are also charts list out the most popular cities for arrive at/departure. Currently, Beijing is the main target city that Chinese are travelling to, and Chongqing is the second most popular city. Meanwhile, Beijing is also the most popular city for departure, which is understandable that most of the Chinese work in capital and travel back to home for celebrating festival. So it is not surprisingly that Shanghai places second in the list.

Map Reviews: 3.5/5 Stars
Though this live map provides useful information, but it is only useful to Chinese or those who knows Chinese as the map does not support other languages, e.g. English. Furthermore, the map does not support pan and zooming that users can either search cities in the search box or mouse click the cities in the chart.

Heat Map: Map shows Countries Are Responsible to Climate Change

If you are wondering which countries emit more carbon dioxide and should be more responsible to climate change, you may refer to the following heat map for more ideas.

This heat map is created by New Scientist that the size of each countries are based on the amount of greenhouse gases they emit.

world-heat-map-countries-that-are-responsible-to-global-warming

There are 0.74 °C warming between 1906 and 2005, and the United States is responsible for 22 percent (0.15 °C ) while China and Russia are responsible for 9 percent and 8 percent respectively.

It is interesting that though the U.S.A., China and Russia are countries should be most responsible to the climate change, United Kingdom and Germany are countries mostly heated.

We all understand that global warming and climate change is a world-wide issue that we all should cooperate together, and tackle it. For more information, you can refer to:

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.

Heat Map: Average Scores for PISA tests around the world

world-heat-map-pisa-test-scores

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: 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.

heat-map-internet-population

 

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.

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.
