Qui sont donc les classes moyennes ? 16 juillet 2014 - Les classes moyennes occupent le débat public. Mais de qui parle-t-on exactement ? Quelques éléments pour tenter d’y voir plus clair. Par Valérie Schneider et Louis Maurin de l’Observatoire des inégalités. Le concept de classes moyennes est vague. Comme pour la pauvreté, il n’existe pas de définition objective des classes moyennes. Pour clarifier le débat, l’Observatoire des inégalités reprend le découpage suivant, identique à celui utilisé par le Crédoc [1] : les 30 % les plus démunis composent les catégories « modestes ». Les limites de cette définition Ce travail a plusieurs limites. Notre découpage est très rudimentaire. L’approche « statistique » - les classes moyennes des revenus sont celles qui se situent autour du revenu médian - permet de mieux comprendre la réalité des revenus. Cette définition utilise des données après impôts. Lire aussi : Photo/ © Dmitry Nikolaev -

What We Eat | National Geographic This interactive was built in conjunction with National Geographic’s Future of Food series. The data was sourced from FAOSTAT. Values reflect domestic utilization for food consumption in each country or region from 1961 to 2011. Food groupings and units of measure vary slightly from those depicted on the FAOSTAT site. Download the data from here. Values for China refer to FAO’s "China, mainland." *Measures for Russia preceding 1992 are represented with U.S.S.R. data. **"Pulses" refers to lentils, beans, and peas. This project was made possible with support from the Grace Communications Foundation. Built and designed by Fathom Information Design © National Geographic Magazine close

Top 60 Chinese Cities Cities are one of the many phenomena that follow a long-tailed distribution. In simple terms there are a few big cities and lots of small ones. The classic way of showing a long tailed distribution (and the method from which the name is taken) is to produce as plot such as that below: The infographic at the top of the post by demonstrates the distribution in a more engaging and constructive way. One method I have used in the past to demonstrate data with a long tailed distribution is the excellent Wordle tool. I have created a Wordle (below) for the same data (downloaded from Chinfographics). World Population Set to Hit 9.1 Billion in 2050 At current growth rates, forecasters expect to see a total of 9.1 billion humans on Earth by 2050, although small shifts in the birth rate might add or subtract one billion people. The rise could be slowed without taking any direct measures to control population. The most effective way to reduce fertility rates is to educate women: worldwide, each additional year of female education lowers the average birth rate further. Greater education correlates with more abstinence, birth control and female employment, each of which lowers birth rates. Source: United Nations Population Division

Yli 8000 lukijaa vastasi: Helsingin keskusta siirtyy kohti Kamppia - Helsinki... Ihmisvirta valuu Kolmensepänaukion yli. Kolmen sepän patsas seisoo yksin aamupäivän auringossa Aleksanterinkadun ja Mannerheimintien risteyksessä. Helsingin Sanomien lukijoiden mukaan tässä on Helsingin keskusta. Joukko nuoria tyttöjä kiiruhtaa Vanhan ylioppilastalon ohi ostoskassit käsivarsillaan, poninhännät heiluen. Patsaalle saapuu pariskunta, joka jää tähyilemään Kampin suuntaan. Osaavatko kokkolalaiset sanoa missä on Helsingin keskusta? "Kyllä se tässä aika lähellä on", arvioi Erik Hagström. Kolmen sepän patsaalta on lyhyt matka tavaratalo Stockmannin etuoville. Helsinkiläinen Sanna Andelin odottaa ystäväänsä Kristiina Viikari a, joka on tapansa mukaan myöhässä. "Tämähän on klassinen maamerkki", Andelin tuumii. Tausta Keskusta on alue, ei piste HS pyysi lukijoita sijoittamaan kartalle Helsingin keskustan. Vastaukset jakautuvat laajemmalle alueelle. "Jotkut yrittävät väittää, että keskusta olisi nykyään Kampissa, mutta minulle se on edelleen tässä."

The Nighttime Earth SAN FRANCISCO — The Earth at night looks more beautiful than it ever has before in these incredible new images from NASA's Suomi NPP satellite. These super-high-resolution images, made possible by a new type of infrared sensor on the satellite, were revealed here at the American Geophysical Union conference Dec. 5.The Visible Infrared Imaging Radiometer Suite has a "day-night band" that can detect natural and man-made light with unprecedented resolution and clarity. It can resolve everything from the nocturnal glow of the atmosphere to the light of a single boat at sea.
