How many people live in Ethiopia?

There should be many homeless people especially in the cities such as: Addis Ababa, Diredawa or Harar, etc. No wonder, even in most developed countries like America, or Europe, there are many homeless people. The issue is not to raise question, the main issue is how, and when to solve this ongoing problem of the world. I am sure, no one would like to choose this life style, it is part of the society's obstacles of this modern time. Ethiopia is being labeled as one of the poorest country in the world. We hear this for many years, but we don't hear any solution which would help that beautiful country to pull out of poverty. Now, I am in my senior years, when I was a student our teachers used to tell us, it is because of backwardness of farming style; since Ethiopia is dependent on farming. This is now 21st century, whereas the advancement of agriculture and technology is immense, still Ethiopia is lingering the same place. Too much talking very little result, instead people should make effort to cooperate; putting aside pike ring on politics, division on race, religion or on class and should work hard and make a great determination for a tangible result for ones and all to cure that country from poverty. Do you get it, please?
