The construction sector — the most labor-intensive part of the private sector — recorded an impressive 34 percent average growth in employment of Saudis, while employment of non-Saudis in the sector grew by 14 percent. The higher growth in Saudi employment in the construction sector is impressive given the particularly high wage differential from non-Saudis. Saudis in the construction sector earned a monthly average of SR3,330 in 2013, while non-Saudis earned only SR1,029.[13]
