What is most likely the biggest concern for someone living in sub-saharan africa

Heat, it's gotta be hot there! ub-Saharan African countries have experienced some of the highest economic growth rates globally over the past 10 years. While this means that people in these nations tend to be more satisfied with their current economies and more optimistic about their economic future than other people around the world, they still face myriad problems. In addition to unemployment, broad majorities rank health care, education, government corruption, crime, access to clean water and energy shortages as some of the biggest issues their countries face. When asked what their nations should focus on improving for the future besides the economy, health care and education emerge as clear priorities.
