From south to north, Togo is made up of five successive geographic regions. In the extreme south is a narrow sandy coastal strip (c.30 mi/50 km long), which is fringed by lagoons and creeks. A region (c.50 mi/80 km wide) of fertile clay soils lies north of the coast. The third region is made up of the clay-covered Mono Tableland, which reaches an altitude of c.1,500 ft (460 m) and is drained by the Mono River. North of the tableland is a mountainous area comprising the Togo and Atakora mts. and including Mt. Agou (c.3,940 ft/1,200 m), Togo's loftiest point. The fifth region, in the extreme north, is the rolling, sandstone Oti Plateau. The country is almost entirely covered with savanna, which has somewhat thicker vegetation in the south and thinner vegetation in the far north. In addition to the capital, other cities include Sokodé, Kpalimé, Anécho, and Atakpamé.
Togo is comprised of more than 35 ethnolinguistic groups, including the Ewe and the Mina in the south and various Voltaic-speaking peoples, the largest of which is the Kabre, in the north. Some 50% of the inhabitants follow traditional African religious beliefs, 30% are Christian (mostly Roman Catholic), and 20% Muslim. French is the country's official language and is used in business; Ewe and Mina are widely spoken in the south and Kabiye and Dagomba in the north.
