التباين المكاني للتركيب النوعي للسكان في المناطق الإدارية و المحافظات بالمملكة العربية السعودية خلال الفترة (2004-2010 م)‎

الملخص EN

Sex ratio (males per 100 females) is one of the most important population composition, because of its interrelationship with many other attributes on one hand, and its demographic, economic and social implications on the other.

In Saudi Arabia, sex ratio has increased from nearly (124) in 2004, to 133 in 2010.

For Saudi population, it increased from (101) to (104) during the period (2004 - 2010).

The ratio also increased from (227) to (238) for non-Saudis during the same period.

In addition, sex ratios varied across administrative areas and governorates for total populations and for Saudis as well.

As expected, Eastern Province, Riyadh, and Tabuk had the highest values, where Baha had the lowest, due to the effect of internal migration.

For non-Saudis, the picture is a little different.

Al-Qassim had the highest sex ratio, while lowest ratio was we noticed in Makkah.

At the level of governorates, Mandaq and Badr Aljanub had the lowest sex ratios for total population and Saudis as well in 2010, and the highest ratio was noticed in Al-Harth.

For non-Saudi, the highest ratio was in Khubash (781), while Al-Harth and Dhamad had the lowest ratio.

Due to the lack of births data from Vital Statistics, the data from population census were utilized to explore the levels of sex ratio at birth, and results came against our expectations, especially for 2010 Census.

This alert for urgent need for data evaluation and serious effort to improve the level of data accuracy.
