Chart: What are the Average Number of Students per Teacher?

Tariq Khokhar's picture

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.

Chart: 2.4 Billion People Live Without Access to Toilets

Tariq Khokhar's picture

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.

Chart: 13% of Global Emissions Covered by a Carbon Price

Tariq Khokhar's picture

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, there's been a threefold increase in the share of greenhouse gas emissions covered by a carbon price. 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. Seven Gigatons of carbon dioxide or about 13 percent of global emissions are covered by a carbon price. Read more in State and Trends of Carbon Pricing 2016.

Chart: Tourism Reaches all-time high in Peru

Erin Scronce's picture

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.

Chart: 25 Years of Growth in The World's Largest Cities

Tariq Khokhar's picture

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.

Chart: 137 Economies Implemented 283 Business Reforms Last Year

Tariq Khokhar's picture

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.

Chart: Where is Gender Discrimination in Business Regulated?

Tariq Khokhar's picture

60% of economies do not have laws mandating gender nondiscrimination in hiring and equal remuneration. Such laws are more common in OECD high-income economies, followed by economies in Europe and Central Asia. Gender equality can make institutions more representative, improve social cohesion and increase productivity.

Quantifying uncertainties in global growth forecasts

Upside risks to global growth have increased since January while downside risks for current-year growth have reached post-crisis highs.

Assessing economic forecast uncertainty and the balance of risks to the growth outlook is critical to effective policymaking. Lower-probability but high-impact events can lead to significant deviations from baseline projections, and this  should be factored into policy design. The World Bank’s most recent Global Economic Prospects unveiled a tool to quantify uncertainty around global growth forecasts and presented it in the form of a fan charts (Figure 1)

The approach adopted in the Global Economic Prospects report consists of two steps.

First, a number of measurable risk indicators that are typical sources of forecast errors for global growth forecasts are selected. Three were chosen: equity price futures, oil price futures and bond term spreads (the difference between short and long term interest rates). For instance, greater volatility in oil price futures could be associated with rising uncertainty around global growth forecasts, while a downward trend in equity price futures could signal rising downside risks to growth.

Second, the probability distributions of forecasts for these three indicators are then mapped to the distribution of global growth forecasts. Both the degree of uncertainty and the balance of risks to the forecast are approximated by weighted averages of the standard deviation and skewness implied by the distributions of expectations for the risk indicators. The weights are estimated in a vector autoregression model (Ohnsorge, Some, and Stocker 2016). To account for potential asymmetry in the distributions of risks, a two-piece normal distribution is assumed, in line with other studies.

Chart: How Does Extreme Poverty Vary By Region?

Tariq Khokhar's picture


Most of the world's extreme poor live in Sub-Saharan Africa and South Asia. While over 1 in 10 people live in extreme poverty globally, in Sub-Saharan Africa, that figure is 4 in 10, representing 389 million people - that's more poor people than all other regions combined.

Chart: Over Half the World Lives in Cities

Tariq Khokhar's picture

Over half the world lives in cities, and those cities are responsible for over 80% of global GDP. However, the high density of people, jobs, and assets which make cities so successful, also makes them vulnerable to the wide range of natural and manmade shocks and stresses increasingly affecting them today.
