In Sub-Saharan Africa and South Asia, there are more than twice as many students per teacher than in Europe and North America. The pupil-teacher ratio is different but related to class size, and is often used to compare the quality of schooling across countries.
Population density is one of the most important statistics for development efforts across many sectors, and since early 2016 we’ve been collaborating with Facebook on evaluating a new source of high-resolution population data that sheds light on previously unmapped populations.
As mentioned in the Living Standards Measurement Study (LSMS) team’s blog post, Facebook Connectivity Lab announced last week the public release of high-resolution population maps for Ghana, Haiti, Malawi, South Africa, and Sri Lanka, jointly produced with the Center for International Earth Science Information Network (CIESIN).
With the building footprints detected by artificial intelligence (AI) over high-resolution commercial satellite imagery, the data sets provide estimates of population at 30m spatial resolution, making these maps the highest-resolution population maps ever produced. This is only possible through recent breakthroughs in computer vision due to deep learning algorithms and technological development of computer processors, as well as the increasing availability of high-resolution commercial satellite imagery.

Editor’s note: This is a guest blog from Jorn Berends and Wendy Carrara on behalf of the European Data Portal. The indicator “Open Data readiness” mentioned in the analysis below is unrelated to the Open Data Readiness Assessment tool developed by the World Bank.
The majority of European countries are improving their Open Data maturity
Open Data is taking off in Europe. Open Data – which refers to publicly available data that is free for all to use – is set to have a monumental impact on societies in the upcoming years, and has a potential market size for the European Union of 75.7 bn EUR by 2020. European countries seem to be on track to reap the potential of Open Data, although a lot of work remains to be done and substantial differences persist between countries. In 2016, with a 28.6% increase compared to 2015, the EU28 and Norway, Switzerland and Liechtenstein – referred to as EU28+ – completed over 55% of their Open Data journey. This shows that, by 2016, a majority of the EU28+ countries have successfully developed a basic approach to address Open Data. This is just one of the conclusions of the 2016 Open Data Maturity in Europe report, prepared by the European Data Portal. What can this report tell us on the countries that are doing particularly well in this regard, what is it that makes them European champions? Furthermore, what can other countries learn from them?
Spain and France are leading the way in Europe, but substantial differences persist
The measurement is built on two key indicators ‘Open Data Readiness’ and ‘Portal Maturity’, thereby covering the level of development of national activities promoting Open Data as well as the level of development of the country’s national data portal. Based on these indicators, the European countries are clustered into four different levels of Open Data maturity: Beginners, Followers, Fast Trackers and Trend Setters.
The UN estimates that 2.4 billion people still lack access to improved sanitation facilities, nearly 1 billion of which practice open defecation. Good sanitation is a foundation for development - conditions such as diarrhea are associated with poor sanitation, and left untreated, can lead to malnutrition and stunting in children.

Note: Only ETS (Emissions Trading Systems) or carbon tax are considered on this graph. Emissions are given as a share of global GHG emissions in 2012. Annual changes in global, regional, national, and subnational GHG emissions are not shown in the graph.
In the last 10 years, . In 2016, about 40 national jurisdictions and more than 20 cities, states, and regions, including seven out of the world’s 10 largest economies, are putting a price on carbon. . Read more in State and Trends of Carbon Pricing 2016.
Peru welcomed 3.2 million tourists in 20 14, the highest number to date. In some regions of the country, like Cusco, tourism is a potential economic lifeline for local people, who can profit from a variety of businesses serving tourists. In 2012, the World Bank Group began working with The Government of Peru to streamline the processes around opening tourism-related businesses because excessive regulations and red tape were holding up investments in new businesses for years. Ultimately, the project shaved 3 years off the business registration process and eliminated 150 unnecessary regulations. With the streamlined regulations in place, investments in hotels in Peru are on the rise. Between 2015 and 2018, Peru is expecting US$1.2 billion in investments in new hotels, an increase from US$550 million during the period 2010-2014.

By 2030, two thirds of the world will live in cities. The world's 12 largest city areas are each home to over 15 million people, and over the last 25 years, cities such as Delhi, Shanghai and Beijing have tripled in size.
Do you know that the ?
Six years ago we launched our open data initiative, and we remain committed to being open about what we know and open about what we do. Readers are probably familiar with our development data and statistics, but there’s a wealth of data available on our project and operations that’s also available in the IATI open data format.
Doing Business 2017 finds that 137 economies worldwide implemented 283 business regulatory reforms last year. This represents an increase of more than 20% over the previous year. Areas of reform include starting a business, paying taxes, getting credit and registering property. Notably, 54 IDA countries implemented 113 reforms.
Earlier this month, over 1,500 people gathered in Madrid for the International Open Data Conference 2016. The World Bank is proud to be a co-organizer of this series of conferences which brings together the global community to shape the future of open data. I was asked to share our thinking on what’s on the horizon for open data and I’ve highlighted a few key ideas below.
Before I carry on though - a quick personal note. Being in Madrid reminded me of my first trip to the city 18 years ago, a few days before I took a new job as the chief of statistics at the UNDP's Human Development Report. Little did I know, while enjoying tapas before flying to New York, that a big part of my job was to become good friends with other international organizations, including the World Bank, so we could get, for free, in Excel sheets, the data they compile and disseminate, often through publication sales.
How things have changed since then with the Open Data Initiative! Now open data accounts for almost two thirds of all web traffic to the Bank and is freely available for anybody to access and use. I’d like to acknowledge my predecessor, Shaida Badiee, for having led the team to make open data happen at the World Bank six years ago, and for continuing to be a force for open data as head of Open Data Watch.
