By 2007, 56.8% of evacuees had found jobs, 22.3% were unemployed and seeking work, and 31.2% of evacuees were unemployed and living off government benefits rather than seeking work. The average monthly salary among the evacuees was NIS 5,380 (about $1,281), a slight rise of 2.1 percent from the average salary the year before. This was, however, a sharp drop of 39% from the settlers average monthly income before the disengagement. The average salary among evacuees was lower than the general average, as compared to above average before the disengagement. In addition to a drop in salary, the evacuees also suffered a drop in their standard of living due to the increased price of goods and services in their places of residence as compared to the settlements. Following the disengagement, settlers were temporarily relocated to hotels, sometimes for as long as half a year, before moving to mobile homes as temporary housing known as caravillas, before they could build proper homes. By June 2014, about 60% of evacuees were still living in these caravillas. Only 40% had moved to permanent housing, although construction of permanent settlements for the evacuees continues to progress. By July 2014, eleven towns for the evacuees had been completed with the expellees joining ten additional towns. Many of the permanent settlements under construction were given names reminiscent of the former Gaza settlements. By August 2014, unemployment among evacuees had dropped to 18%. In 2010 a bill was introduced in the Knesset providing a basic pension to business owners whose businesses collapsed.
