The main trends of African migration include large numbers of people moving within the continent, often to countries belonging to the same regional economic communities. The top destination countries are South Africa, Cote d'Ivoire, Nigeria, and Ethiopia. People migrate for economic reasons like unemployment, climate factors like droughts and floods, and conflicts. While migration provides economic benefits, it can also cause social tensions as native populations fear losing jobs to migrants or see migrants as threats to security. South Africa in particular has faced regular xenophobic attacks against migrants.
