Togo is a small country, 600 km long and 50 to 100 km wide. It is bordered to the south by the Gulf of Guinea, a low-lying sandy coastal area on the Atlantic Ocean, and to the north by the wooded savannah typical of West Africa. The population in 2020 was 8,608,444, composed of about thirty ethnic groups (the Ewe and Guin in the south, the Kabyè in the centre and north). 60% of the population is under twenty years old, but the infant mortality rate is very high. The time zone is one hour behind Paris in winter, and two hours in summer.
