Within the period of 1997 to 2007, the mean residential areas owned by the first to the last tenths have had fluctuations in different city spots, i.e. the mean residential area owned by the first tenth as the lowest tenth of the society has increased from 57.9 square meters in 1997 to 82.7 in 2007. On the contrary, the mean residential area owned by the last tenth has decreased from 139.5 to 122.1. In the year 2007, the mean residential area owned by the first tenth was 82.7 square meters, and this value was 60.7 square meters for the second tenth, 107.7 for the third, 99.7 for the fourth, 117.5 for the fifth, 105 for the sixth, 1.6 for the seventh, 102 for the eighth, 112.9 for the ninth and 122.1 for the last tenth which is the highest mean value of the residential area. Within the period of 1997-2007 the rate of owning a house in urban areas of the province of Lorestan has decreased from 54.5 percent to 50 percent. This value has had a great reduction in the second tenth and has decreased from 86.4 percent in 1997 to 34.5 percent in the year 2007. The rate of house ownership has increased in the third tenth, decreased in the fourth tenth, increased in fifth, sixth and seventh tenths and decreased in the last tenths. Tenancy percentage has increased in the first, second, fourth, ninth and last tenths and decreased in the others within the period of 1997 to 2007. Based on the mean price per square meter, in the year 2007 house ownership ability is on average 4.8 square meter of a residential area in the first tenth and about 13 square meters in the fifth tenth. Saving tendency is 5 percent in the first tenth, 4 percent in the second tenth, 6 percent in the third tenth, 8 percent in the fourth tenth, 9 percent in the fifth tenth, 9 percent in sixth, seventh and eighth tenths, 22 in ninth tenths and 19 in the last tenth.

The poverty line in the area of housing has increased within the period of 1997 to 2007 based on both mean value and mid value. In the year 2002, the average poverty line was 4 based on mean value and 36 based on mid value. These amounts were 9 and 9.2 respectively in the year 2007. Conclusion: The lower tenths of the residents of urban areas in Lorestan province are of the highest unemployment rate, lowest Income, and highest rate of tenancy the value of which reduces as we move towards higher tenths.
