The number of young people in the Arab population is high: 49% are under the age of 19, compared with 33% in the non-Arab population. At the same time, however, the attitudes regarding employment and education of Arab women are changing. This change is reflected in the reduction of fertility rates among Arab Muslims from 5.5 children per woman in 1980 to 3.9 in 2007. Jewish and Arab workers each account for just over one-third of the workforce in the construction sector, with cross-border workers and foreign workers together making up the other third.
