Over 70% of the  inhabitants live on its main island, Tongatapu. Although an increasing number of Tongans have moved into the only urban and commercial centre, Nukuʻalofa, where European and indigenous cultural and living patterns have blended, village life and kinship ties remain influential throughout the country. Despite emigration, Tonga grew in population from about 32,000 in the 1930s to more than 90,000 by 1976.
