Namibia is a multiparty democracy, though the ruling party, SWAPO, has been in power since independence. Protections for civil liberties are generally robust. Minority ethnic groups accuse the government of favoring the majority Ovambo in allocating services. Nomadic San people suffer from poverty and marginalization. Other human rights concerns include the criminalization of same-sex sexual relations under colonial-era laws, and discrimination against women under customary law and other traditional practices.
