The economic activity of the Australian Capital Territory is heavily concentrated around Canberra. A stable housing market, steady employment and rapid population growth in the 21st century have led to economic prosperity and in 2011 CommSec ranked the ACT as the second best performing economic region in the country. This trend continued into 2016, when the territory was ranked the third best performing out of all of Australia's states and territories. There is a higher proportion of young adults in the region compared with other Australian states or territories. Approximately one-fifth of ACT residents were born outside Australia, mainly in the United Kingdom. Almost one-fifth speak a language other than English at home, the most common being Chinese.
