children in Oslo compared to 7.9% in the entire country of Norway. Gamle Oslo had the highest number of all municipalities and districts in the country with 32.5% of all children in poor families. The figures for Grünerløkka and Sagene were 25.2% and 21.8% respectively, the four districts in Groruddalen and Søndre Nordstrand were between 18% and 20%, the inner west between 12% and 14%, Østensjø 10% and the outer west 5%. 78% of the children are children of immigrant families from outside the west. These families are marked by low employment and large families. The division by districts is also explained by the fact that there are apartments with low prices and many municipal apartments. The high rate of child poverty in Oslo is mostly an effect of the large immigration to the city and the immigrants' problems to establish themselves in the job market and receive enough income to support large families. Apartment prices in the West End rose more than the prices in the East End in the 21st century. From 2003 to 2006 prices in the districts of Stovner, Grorud and Søndre Nordstrand rose by less than 25%, and the prices in Frogner, St. Hanshaugen and Ullern rose by around 40%. All five West End districts had higher price increases than the highest increase in the East End. The price per square metre for apartments varied in November 2008 in the East End from 21,000 in Søndre Nordstrand to 33,000 in Sagene, and in the West End from 36,200 in Nordre Aker to 43,200 in Frogner. In a study by the municipality of Oslo, the answers about the overall impression of one's living area, how fine it is there and how proud one is of living there, the outer west got the best result. In the inner west the population is a bit more satisfied than in the inner east. Of all East End districts, Østensjø has clearly the most satisfied population. Oslo's neighbouring municipalities follow the east-west boundary line. Apartment prices in 2009 were between 20% and 40% higher in neighbouring municipalities in the west (Asker and Bærum) than in neighbouring municipalities in the east (Follo and Nedre Romerike). The incomes are similarly divided, with differences from a couple per cent to about 50% between different municipalities and types of families. The districts in the inner east have under the past 20 years had a
