摘要：Past population census data of Sultanate of Oman are analyzed to find the best-fitted age distribution model applying chi-square goodness of fit test and model selection criteria. It is observed that the age distribution of the Omani population is exponential. The population figures for different age groups of Oman are estimated using exponential distribution. Age distribution of Omani population is compared with that of other Gulf countries and also with some developed nations. It is observed that, unlike other developed countries of the world, the age distribution of Omani population does not change significantly over the last two decades. It is also observed that the median age of the Omani population is about half of that of other developed nations. Ageing is not a problem for Oman or Gulf countries, but it is a big issue for most developed countries. Young populations in Oman are significantly higher than that of developed countries.
