The China Strike Map

The ever growing manufacturing and construction industries in China have worked wonders for the Chinese economy and for the large number of Chinese billionaires who have struck it rich on the back of this industrial strength.

Unfortunately the average Chinese worker has not substantially benefited from the thriving economy. In fact they are often forced to work in what can only be described as inhuman conditions. Workers in Chinese factories often work 11 hour days, six days a week and can be paid a lot less than a dollar an hour. To do this they often live in dormitory conditions and very rarely get to see their families.

China does have labour laws but these labour laws are widely ignored. One response to the harsh working conditions, poor pay and ignored labour laws has been the growing number of wildcat strikes by workers in China. These strikes are most often not reported by the Chinese media. Which is why the China Labour Bulletin's Strike Map is so important.

The CLB Strike Map plots strikes across China. The map's default view shows the location of labour strikes over the previous six months. However you can change the dates of the strikes on the map, which is particularly useful in tracking the number of strikes reported to the China Labour Bulletin over time. You can also filter the results shown on the map by industry and by the number of strikers participating in a strike.

The China Labour Bulletin also produce an interactive China Work Accident Map, which tracks injuries and deaths which occur in Chinese factories and other places of work.

Mapping Latino Voters

California has the largest number of eligible Latino voters of any state. 7,698,000 Latino voters can vote in California. In total 30% of the state's voters are Hispanic. In West Virginia on the other hand less than 1% of voters are Hispanic. Only 13,000 Latino voters are eligible to vote in the state.

In the 2018 midterm elections there will be more than 29 million Latino registered voters across the whole of the United States. Pew Research has released an interactive map which shows you how many Latino voters there are in each state and in each congressional district.

Mapping the Latino Electorate is a choropleth map which shows the percentage of the voting public who are Hispanic in every state and congressional district. The darker the shade of green a state is colored on the map then the higher the percentage of eligible voters are Hispanic. You can hover over individual states and congressional districts to view the exact percentage of eligible voters who are Hispanic. You can also view more details on each state's Hispanic population in the table below the map.

Shipwrecks of the First World War

The Forgotten Wrecks of the First World War is an interactive map plotting the locations of historical wrecks from the Great War. It shows the known locations of wreck sites in and around the seas, coasts and rivers of the UK.

The wrecks included on the map include merchant & naval ships, passenger, troop & hospital ships and submarines. It also shows the locations of ports, wharfs and coastal buildings which were wrecked during the war. You can search the map for individual wrecks by the name of the vessel. You can also refine the wrecks shown on the map by vessel type, use at time of loss or by year.

If you select an individual wreck on the map then you can view details about the type of vessel and the year it was wrecked. You can also learn more about the vessel's size, cargo, destination and the name of the captain. The details for each wreck also include any information that is known about the vessel's loss and, where available, images of the wrecked vessel.

Americans don't know their Alsace from their Bilboa

Holiday Cottages asked Europeans and Americans to identify the locations of countries around the world on a map. They then compared the results to see whether Americans or Europeans have a better understanding of world geography. The results were not good for the Americans.

Where in the World? A Global Look at Geographic Recognition presents the results of a test involving over 1,000 people being asked to point out countries on a map of the world. The results are very interesting. Holiday Cottages has created an interactive map which allows you to view all the individual guesses made for each country. The map also tells you the percentage of people who guessed the location of the country correctly. In addition it lists the countries which were most often incorrectly identified instead.

Holiday Cottages went on to compare the accuracy of American and European answers. It discovered "that Europeans were universally more apt at identifying world countries than Americans". When asked to identify a country on the map in Asia, Africa, the Middle East and South America Europeans were always better at correctly pointing out the country on a map.

However the results are not as clear cut as Holiday Cottages suggests. Holiday Cottages are keen to argue that Americans have a poorer understanding of world geography than their European cousins. They therefore forget to point out that Americans are far better at identifying European countries than Europeans are at identifying US states. Holiday Cottages has created tables showing how well different generations of Americans can identify European countries and how well the different generations of Europeans were at identifying US states. All generation of Americans are better at identifying European countries than all European generations are at identifying US states.

New York's Fast Food Hot Spots

Last year the London mayor Sadiq Khan announced he wanted to introduce fast food exclusion zone around London schools. The purpose of these exclusion zones are to help fight the rise of child obesity. The zones don't apply to existing fast food outlets but would apply to anyone planning to open a fast food restaurant in the future.

You can see where these fast food exclusion zones will exist on Dan Cookson's interactive map London Schools 400m Exclusion Zones. Dan's map places a 400m circle around every school in London to show all the areas where new fast food outlets will be banned under the new policy.

New York has yet to follow suit with its own fast food exclusion policy for schools. However if you are a parent of a child in the Big Apple you can refer to the New York Fast Food Map. This hexbin map visualizes the concentration of fast food restaurants in New York. The colors of the hexagonal areas on the map relate to the total number of fast food eateries within each area. The map also shows the location of all the city's middle and high schools.

You can read more about the map and the data behind it on A Walk to Fast Food.

Flying Over Trump's Wall

The Washington Post has created an impressive fly-over of the USA - Mexico border. The map takes you on a tour of the entire border, from the west coast to the Gulf of Mexico. The Post's Borderline interactive gives you a complete overview of the invisible and physical barriers which already separate the two countries and the huge job that Trump has ahead of him if he wants to build his wall.

The map provides an oblique bird's eye aerial view of the border. As you scroll down on the page you get to fly along the entire route of the border. As you progress along this border information windows appear which tell you about the existing use of fences or walls along the border. The information windows include quick links which allow you to jump ahead, along the border, to the next annotated part of the Post's interactive.

The Washington Post's interactive map is just the latest in a long line of attempts to map and document the huge job that Donald Trump has set himself. For example the Berliner Morgenpost's Trump Wall Comparison Map allows you to overlay an outline of Trump's proposed border wall between the USA and Mexico on any other location on Earth.

You can also get a good sense of the scale of construction needed to build Trump's wall in a video from the Intercept. The Intercept downloaded and stitched together 200,000 satellite images to create a huge strip map of the U.S.-Mexican border. You can view this strip map in Visualizing the U.S.-Mexico Border, a short video which pans along the whole border.

KPBS submitted a number of Freedom of Information requests to U.S. Customs and Border Protection in order to learn more about the 653 miles of the wall that already exist. You can explore what they discovered on their interactive map America's Wall. The Reveal has also investigated where the border is already fenced. You can explore Reveal's work on their The Wall interactive map. The map shows the current fence and shows where it is a 'vehicular' and where it is a 'pedestrian' fence. The map also shows where no fence currently exists.

USA Today has also completed a whole series on the US - Mexico border. USA Today's The Wall - an in-depth examination of Donald Trump's border wall includes interviews, podcasts, virtual reality and an interactive map of the border.

Unequal Neighbors

This interactive map is an interesting Visualization of Differences in GDP per Capita of Neighboring Countries. Essentially the map makes obvious where countries around the world have under-performing economies in comparison to their immediate neighbors.

On the map the reddest countries are those with the lowest relative GDP compared to their immediate neighbors. In other words the reddest countries have the poorest performing economies when they are directly compared to the economies of neighboring countries. For example Mexico has a relativity low GDP per capita when compared to the USA. If Mexico's immediate neighbors were in South America it wouldn't appear so red on the map.

Another way to assess the health of a country's economy is to examine its level of debt as a percentage of GDP. Japan has the highest level of government debt in the world using this metric. The Japanese government currently owes 214% of Japan's GDP. The PIG's (Portugal, Italy and Greece) all still owe over 100% of their GDP. The United States just misses out on being a member of the plus 100% club with a government debt of 98%.

McKinsey & Company has created an interactive map that visualizes the debt of 51 different countries around the world. The Visualizing Global Debt map provides a choropleth view of how much debt is held by each of the 51 different countries and how that debt has progressed since the global financial crisis of 2008.

The map doesn't just look at government debt. You can also visualize household debt in each of the 51 featured countries. Switzerland is the country with the highest household debt, with an average household debt of 127%. Household debt includes such things as mortgages, student loans and consumer credit. Household debt in the USA is currently 78% of GDP.

Those who like their GDP served straight up can always refer to the World Bank's map of GDP per Capita. This interactive map provides a simple choropleth view of every country's GDP per person. In 2017 the five countries with the highest GDP per capita were Luxembourg, Macao, Switzerland, Norway and Iceland.

Mapping the Impact of Agriculture

Esri has released the second installment in its Living in the Age of Humans series. This new story map, entitled The Living Land, explores how humans use the Earth's limited land space.

This installment of Living in the Age of Humans focuses on the impact of agriculture, which accounts for the vast majority of the Earth's surface which has been modified by humans. Just half a percent of the total land area on Earth is used by humans as urban areas. However twenty one percent of the land area of Earth is used by us for agriculture, including cropland and intensively used pastureland.

As you progress through The Living Land you can view where this cropland and pastureland exists around the world. You will also learn more about which crops are grown in different areas of the world and in which quantities. You will also discover what effects these crops have on the land where they are grown.

Unequal Education in the USA

ProPublica's Miseduction map shows where black and Hispanic students are missing out on educational opportunities compared with white students. The map uses data from the U.S. Department of Education to show which schools and districts have the best and worst racial disparities in educational opportunities and school discipline.

The map allows you to view racial disparities between either educational opportunities, school discipline, segregation or achievement. You can also switch between viewing the racial disparities for either black or Hispanic students.

ProPublica has also created a table which lists how much more likely white students are likely to be in an advanced placement class than black or Hispanic students in every state. The table also shows how much more likely black or Hispanic students are likely to be suspended compared to white students. The columns in this table can be switched to show the results in ascending or descending order so you can quickly view which states have the best and worst records.

Earlier this year Vox looked at how American schools could become less segregated. They argue that the segregation of students in the country's schools is a political decision. There is no good reason why schools are segregated and this segregation can be easily overcome if there is the political will to give all Americans equal educational opportunities.

In We can draw school zones to make classrooms less segregated Vox looks at how school districts can be gerrymandered to make them less segregated. The article includes a map tool which allows you to visualize how segregated schools currently are in your town. If you enter your school district into this tool you can view a choropleth map showing the percentage of students in each elementary school zone who were black or Hispanic in the 2013 school year.

The map allows you to view the current situation in your district using the current zoning regulations and compare this with how it would look if students were just assigned to their nearest school. Beneath the map you can see a graph which reveals if your local zoning regulations are lessening school segregation or making segregation worse

Every House of Representatives Election

Electing the House of Electives is a new interactive data visualization of every House of Representatives election since before the Civil War. The map allows you to explore the historical swings of political power at both the national level and, closer to home, at the regional level.

The interactive map is easy to navigate. You can view the election results for any year simply by selecting a year from the timeline beneath the map. This timeline also acts as a chart showing the number of Republican and Democrat representatives elected in each election. The map itself is colored to show which party won in each district. If you click on a district on the map you can view the name of the winning representative and the percentage of their vote.

The map allows you to switch between a choropleth and a cartogram view. The cartogram view provides a better picture of the political balance across the population as it more accurately visualizes the urban vote which is under-represented in the choropleth view.

Electing the House of Electives was created by the Digital Scholarship Lab at the University of Richmond and the Department of History at Virginia Tech. The data for the maps comes from a number of sources. This data can be downloaded from Virginia Tech.
