According to a World Bank report, about 80% of the world’s poorest people live in just 10 countries. Several smaller countries, however, actually have a greater proportion of people living in extreme poverty.
"While smoking prevalence has declined in the past 30 years, the growing population has driven up the number of smokers. This interactive data visualization designed by the Institute for Health Metrics and Evaluation (IHME) allows you to explore how smoking trends have changed from 1980 to present. Dig down to specific trends by region, country, age, and gender, and even see the data used to generate estimates.”
According to the latest Food Price Watch, 1/4 to 1/3 of all food produced for human consumption is lost or wasted, annually. In regions such as Sub-Saharan Africa and South Asia, which are plagued with undernutrition, this translates into 400-500 calories lost per person, per day.
Check out how much food is lost or wasted in your region.
According the latest Global Economic Prospects Report the world economy will strengthen in 2014. Much of the initial acceleration will reflect a pick-up in high income country growth, which after years of extreme weakness and outright recessions, appear to be finally emerging from the global financial crisis.
The average new home varies in size from 45 m2 (484 ft2) in Hong Kong up to 214 m2 (2,303 ft2) in Australia. US home size has fallen a little since the recession, to 201 m2 (2,164 ft2) in 2009. UK house size is relatively small at 76 m2 (818 ft2) while Canadian houses are quite big at 181 m2 (1,948 ft2). For China the data only reflects urban properties, which now average 60 m2 (646 ft2) and have almost doubled in size in the last 15 years.
This interactive visualization lets you explore the business environment of different countries using data from The World Bank Group’s Doing Business project which provides quantified, comparable measures of business regulations and their enforcement across 189 economies.
Published annually since 2002, Doing Business measures the efficiency and strength of laws, regulations and institutions relevant to domestic small and medium-size companies throughout their life cycle.
The interactive chart below shows average “survival curves” for females from 2005-2010. You can see that in Japan about 78% of female newborns survive up to age 80, whereas about 7% of female newborns survive up to that age in Sierra Leone.
For the same period, life expectancy at birth for females was 86 years in Japan and 47 years in Sierra Leone. Looking at survival curves shows the distribution of mortality by age whereas life expectancy just offers a snapshot for a population.
This map shows current population growth trends, based on data from a new UNFPA report.
"The blue countries are growing, with darker blue countries growing very rapidly. Purple countries are growing slowly or are about stagnant, with less than 1% population growth every year. Red countries are actually shrinking, typically because people are leaving and/or because they’re not having enough babies, and that can cause huge problems.”
The Global Gender Gap Report 2013 benchmarks national gender gaps in 136 countries based on economic, political, education and health criteria. This interactive map visualizes a ranking of the countries evaluated.
Afghanistan, Pakistan and Nigeria are the only the three countries where polio is still endemic.
By the end of 2012, the total number of polio cases worldwide dropped 66% over the previous year to just 223. The map above shows the tremendous progress that’s been made in eradicating the disease since 1988
Tim Evans at the World Bank argues that for countries to fully eliminate polio, integrating polio eradication into routine immunization and broader health service delivery will be critical, particularly in communities where the security situation hampers highly visible health campaigns.
Which Developing Countries Receive the Most Remittances?
According to a new report, developing countries will receive $414 billion in remittances in 2013. Remittances to India and China will total $131 billion. Global remittances, including those to high-income countries, are estimated to reach $550 billion in 2013.
The Investments to End Poverty Report from Development Initiatives illustrates the changing picture of international resource flows into developing countries and promotes the idea that it’s all resource flows - not just aid - that have a role to play in ending poverty.
The Global Child Mortality Rate Has Dropped 47% Since 1990
New estimates of child mortality were released today by the UN Inter-Agency Group for Child Mortality Estimation(UN IGME), and show the global child (under-five) mortality rate has dropped 47 percent since 1990 - from 90 deaths per 1,000 live births in 1990, to 48 in 2012. This decline represents substantial progress, but the rate of decline remains insufficient to reach Millennium Development Goal 4 (MDG 4) of a two-thirds reduction in 1990 levels by 2015.
This image shows what would happen if all the Earth’s water - everything from oceans and seas to ice caps, lakes and atmospheric vapor - was removed from the surface and combined into a single sphere.
By volume, the Earth is about 1 trillion or 1,000 billion cubic kilometers. All of the earth’s water comes in at a thousand times smaller, in a sphere with a volume of 1.4 billion cubic kilometers and about 1,400 kilometers in diameter - that’s about the length of Madagascar.
Rank and compare causes and risks in different countries based on deaths, Years of Life Lost (YLLs), Years Lived with Disability (YLDs), and Disability-Adjusted Life Years (DALYs) by age, group and sex. Click on any country to rank the causes for that country, and then see how the country compares to others.
“Right now, with a couple of exceptions, Africa’s population density is relatively low; it’s a very big continent more sparsely populated than, say, Europe or East Asia. That’s changing very quickly. The continent’s overall population is expected to more than quadruple over just 90 years, an astonishingly rapid growth that will make Africa more important than ever.”
Today, the world has the largest youth population in history. There are more than 1.2 billion young people between the ages of 15 and 24, and 90% of them live in developing countries like Sierra Leone.
Github is an online service that helps programmers share and collaborate around software they create.
"In an effort to help promote, highlight and grow Africa coders we’ve created this map which shows the location and density existing GitHub users (primarily programmers) in Africa. This represents approximately only 0.12% of all GitHub users worldwide."
Note: This map only counts people who have set their GitHub profile location to an African country or city.
Last month, we helped organize a hackathon in Kathmandu, Nepal, to find innovative solutions to tackle violence against women. From alert systems to reporting abuse and seeking care, hackers wearing black t-shirts worked on 17 projects geared toward helping women and girls.
Recent data are not regularly not available in Nepal, but a demography and health survey in 2011 included questions about domestic violence.
“More than one-third of all homicides of women are committed by a current or former partner. And nearly a third of women report having experienced violence at some point in their lives, either physical or sexual, at the hands of a partner.”
City populations are growing worldwide, and the amount of municipal solid waste (MSW) — one of the most important by-products of an urban lifestyle — is growing even faster than the rate of urbanization.
Today, urban dwellers generate about 1.3 billion tonnes of waste per year. Ten years ago, they generated 0.68 billion tonnes; by 2025, they are estimated to generate 2.2 billion tonnes per year.
How much rubbish does one city dweller in Europe generate per day? Russian Sphinx has cleverly mapped it out with interactive dataviz tools actual trash.
"Subnational conflicts are some of the most protracted, deadly, and complex forms of conflict in the world today. From 1999 to 2008, more people were killed in subnational conflicts than every other form of conflict combined, including fragile state conflicts like the war in Afghanistan. In Asia, the challenge they present is staggering. This visualization explores subnational conflict in Asia, and presents some of the key findings of The Asia Foundation’s latest report, The Contested Corners of Asia: Subnational Conflict and International Development Assistance."
Explore the full interactive dataviz to learn about the history of conflict, international aid flows and evolving conflict case studies through time.
"Ever wonder what it would look like to plot every single geotagged tweet since 2009 on a map? Twitter has done just that…They use billions of geotagged tweets: Every dot represents a tweet, with the brighter colors showing a higher concentration of tweets.”
Web Aquarium Shows World's Declining Fish Population
Today is World Oceans Day, and sadly the data on the health of the oceans are grim. For example, 90% of the big fish in the oceans are gone, largely due to overfishing.
What do emptier waters look like? The Guardian have compiled 200+ oceans-related datasets into an interactive web aquarium that shows the decline in fish populations over the past 100 years. Dive into the full interactive dataviz to see it for yourself.
Another way to visualize global access to energy, from The Economist:
"Some 1.7 billion people gained access to electricity, and 1.6 billion to modern fuels for household cooking between 1990 and 2010. The world’s population increased by a similar amount, so the proportion of those who have access to modern energy sources rose."
Infant Mortality: Magnitude, Disparities and Trends
Ramon Martinez, Information System and Health Data Analyst, created and submitted this data visualization.
The infant mortality rate (IMR) is measured as follows: the number of babies who die before reaching their first birthday divided by number of live births in a specific place and year. The highest infant mortality rates in the world are in Africa and Southeast Asia.
How People Use Mobile Phones in Emerging Markets in Asia
Social media apps are the most commonly used mobile apps in emerging countries in Asia, according to a survey conducted by Jana, a Boston-based mobile technology company. For example, 87% of respondents in Indonesia have social media apps on their mobile phones. The second most common mobile apps are games.
Jana surveyed over 3000 people in Bangladesh, India, Indonesia, Pakistan, the Philippines and Vietnam to find out how mobile phones are being used. Explore the results in their interactive infographic.
