Primary school entrance age and duration
Education for All (EFA) and the Millennium Development Goals (MDG) both aim at universal primary education. All children worldwide should attend and complete primary school by 2015. However, national education systems differ and the meaning of primary education for all children therefore varies from country to country.
The UNESCO Institute for Statistics (UIS) maintains a database with the entrance age and duration of primary education for 204 countries and territories. Table 1 summarizes the distribution of primary school entrance ages from the UIS database. In nearly two thirds of all countries, children are expected to enter primary school when they are 6 years old. In a further third of countries, the entrance age is 5 or 7 years. Two countries have different primary school entrance ages, Ireland with 4 years and Mongolia with 8 years..
Table 1: Primary school entrance age
Source: UIS Data Centre, May 2010.
The geographic distribution of the entrance ages is shown in the map in Figure 1. 6 years is the common primary school start age in most of North and South America, Western Europe, Africa, the Arab States, and East Asia, with some exceptions. 7 years is more common in Eastern Europe, Central Asia, and parts of Sub-Saharan Africa. 7 years is also the primary school start age in some large countries: Brazil, China and Russia.

The duration of primary school, shown in Table 2, ranges from 3 to 8 years. In 126 of 204 countries and territories, primary school has a duration of 6 years. In about 25 countries each, the duration is 4, 5 or 7 years. The shortest duration, 3 years, is reported for Armenia, Russia and Turkmenistan. In Ireland, which has the earliest entrance age with 4 years, children have to attend primary school for 8 years.
Table 2: Primary school duration
Source: UIS Data Centre, May 2010.
The map in Figure 2 illustrates the primary school duration by country. 6 years is the most frequent duration in North and South America, East Asia and the Pacific, the Arab States and most of Africa except for Southern Africa, where 7 years is the most common primary school duration. In Central and Eastern Europe, Central Asia, and South and West Asia, primary education is typically shorter, with a duration of 4 or 5 years.

What are the implications of the different primary school entrance ages and durations for the MDG and EFA goal of universal primary education by 2015? The official duration of primary education is closely linked to the number of children out of school. As an example, assume that a country has a primary school duration of 5 years and that the number of children in and out of school is evenly distributed across the official primary school ages. Shortening the duration of primary school from 5 to 4 years would immediately reduce the number of children out of school by 20 percent. However, the primary school net enrollment rate, the official indicator for the MDG of universal primary education, would not change and the country would therefore not be closer to the 2015 goal.

A YouTube video typically has 50% of its views in the first 6 days, and 75% in the first 20
"A video on YouTube gets 50% of its views in the first 6 days it is on the site, according to data from analytics firm TubeMogul. After 20 days, a YouTube video has had 75% of its total views.
That's a really short life span for YouTube videos, and it's probably getting shorter. In 2008, it took 14 days for a video to get 50% of its views and 44 days to get 75% of its views."

China has 105 million browser game users, including 92 million social game users
"The China Internet Network Information Center (CNNIC) has released its 2010 China Browser Game Survey Report, showing that as of April 2010, China had 105 mln browser game users, including 92.09 mln social game users, 23.84 mln massively multiplayer online (MMO) browser game users, and 37.91 mln single-player browser game players, with some user overlap between all three categories.
The report said that, at a usage rate of 87.7%, social games possess significant commercial potential due to user tolerance towards advertising. CNNIC reported that 71.3% of social game users are exposed to in-game advertisements, of whom 2.2% said they would purchase goods advertised. The report also showed that social games can help boost stickiness of social networking sites. When asked whether they would leave a social networking site if it lacked games, 27.4% of respondents said "definitely" and 45% said "maybe.""

Wired sold more than 24,000 copies of its iPad app in the first 24 hours
"Wired magazine sold 24,000 copies of its iPad app in the first 24 hours it was available in Apple’s iTunes store, company executives said. The app was released shortly after midnight Tuesday.
It’s difficult to put that number in context, because there aren’t many iPad magazine apps yet, these being the earliest days of the new platform for which publishers have high hopes but little track record to parse."

Notes:
1 - "In the April Mobile Metrics report we take a look at unique Android and iPhone devices in our network. The numbers represent the unique devices that requested at least one ad from the AdMob network in April 2010. Please note these are not market estimates, rather data from our network that could be used to inform relative comparisons between the platforms."
2 - "Keep in mind that these unique device numbers are from the AdMob network only and reflect the adoption of our products and business operations. We don’t know what percentage of the total universe of iPhone and Android devices AdMob reaches. However we believe the data is useful on a relative basis given the large sample size of devices in our network."
