throughout the Solomon Islands. The Society of Saint Francis, founded as a union of various Franciscan orders in the 1920s, has experienced great growth in the Solomon Islands. Other communities of religious have been started by Anglicans in Papua New Guinea and in Vanuatu. Most Melanesian Anglican religious are in their early to mid-20s – vows may be temporary and it is generally assumed that brothers, at least, will leave and marry in due course – making the average age 40 to 50 years younger than their brothers and sisters in other countries. Growth of religious orders, especially for women, is marked in certain parts of Africa. Worldwide distribution Anglicanism represents the third largest Christian communion in the world, after the Roman Catholic Church and the Eastern Orthodox Church. The number of Anglicans in the world is over 85 million . The 11 provinces in Africa saw growth in the last two decades. They now include 36.7 million members, more Anglicans than there are in England. England remains the largest single Anglican province, with 26 million members. In most industrialised countries, church attendance has decreased since the 19th century. Anglicanism's presence in the rest of the world is due to large-scale emigration, the establishment of expatriate communities, or the work of missionaries. The Church of England has been a church of missionaries since the 17th century, when the Church first left English shores with colonists who founded what would become the United States, Australia, Canada, New Zealand, and South Africa, and established Anglican churches. For example, an Anglican chaplain, Robert Wolfall, with Martin Frobisher's Arctic expedition, celebrated the Eucharist in 1578 in Frobisher Bay. The first Anglican church in the Americas was built at Jamestown, Virginia, in 1607. By the 18th century, missionaries worked to establish Anglican churches in Asia, Africa, and Latin America. The great Church of England missionary societies were founded; for example, the Society for Promoting Christian Knowledge (SPCK) in 1698, the Society for the Propagation of the Gospel in Foreign Parts (SPG) in 1701, and the Church Mission Society (CMS) in 1799. The 19th century saw the founding and expansion of social-oriented evangelism with societies such as the Church Pastoral Aid Society (CPAS) in 1836, Mission to Seafarers in 1856, Girls' Friendly Society (GFS) in 1875, Mothers' Union in 1876, and Church Army in 1882, all carrying out a personal form of evangelism.
