The National Center for Statistics & Information, Oman, is a great place for statistical data on population, education, demographics of all sorts. It has many graphic tools with interactive features to find out specific information based on Governorate, Wilayat or Town levels, depending on information being available or not.
Oman National Spatial Data Infrastructure is a great mapping tool with all the information available in maps! Users can use the 'Oman Explorer' to toggle between various 'layers' of data that is available with the NCSI and available to the public. You can also print your area of interest, export the data in GIS or AUTOCAD formats, among others. Be careful to check the data in case it has not been updated.
