Population Explosion in Nigeria

 When i was growing up, the population of Nigeria was 148million, then in 2013, the Boko Haram terrorist group came in nd started reducing the poplation with suicide bombers, city attacks that resulted in the loss of millions of lives and properties. In 2017 the country faced economic recession which also resilted in the loss of lives as well. Almost every week, more than 500 families leave the country to stay abroad.
  April 2018 came and and then population result was over 198million and am like what happened to the country, the economy is still bad, the terrorists are still hunting us, death rate is still high, where are the people coming from? are people coming from other Nations?

Please tell me what you think
