Expats have been moving massively to Oman since the past five years. According to latest figures published by the National Center for Statistics and Information (NCSI), the country's total population of over 4.44 million inhabitants include 45.5% of expatriates as at May 2016. Nationals, for their part, constitute 50.5% of the total population.
In 2010, expatriates accounted for only 29% while in 2011 figured rose up to 38.9%. In April 2016 only, a 1% rise was registered. Note that most of these expatriates come from India (687,592) and Bangladesh (630,433). This increase is attributed to huge development projects started across the country and requiring foreign manpower.
The NCSI also revealed that most residents, that is over 2.4 million people including 891,942 expats against 503,470 nationals, live in Muscat. North Batinah is the second most densely populated area with more than 719,000 residents including 241,142 expatriates.
