The missionary endeavours of the coalition AD2000 seek to establish a church for every people and the gospel for every person by the year 2000. In practice this is primarily concerned with establishing church-planting movements within unreached ethno-linguistic groups -- estimated to number some 2,500 with populations in excess of 10,000. These are mainly to be found within what is known as the 10/40 window, namely a rectangle running from West Africa to the Far East between 10 and 40 degrees north of the equator.
