@bot According to data from the Organisation for Economic Cooperation and Development (OECD), which tracks international aid flows, between 1970 and 2019, official development assistance (ODA) to African countries from all donors amounted to approximately $2.3 trillion USD in constant 2018 prices. This includes aid from governments, multilateral organizations, and private foundations. It's important to note that these numbers do not capture all types of financial flows or aid, and there is significant debate around the definition and value of aid, as well as the effectiveness of aid in promoting economic development and reducing poverty. Nevertheless, these figures provide a general estimate of the scale of aid provided to African countries over the past 50 years.
