"The scope of the SACC is all countries, as defined above, currently existing in the world. Most countries are separately identified in the classification, even though many of them are statistically insignificant in the Australian context. A small number of geographic areas have not been separately identified but have been included in residual (not elsewhere classified) categories. Most of these entities have no permanent civilian population and are not significant in terms of social or economic statistics. This comprehensive coverage makes the classification useful for a range of applications and increases its longevity."
