The economic growth of a country is often judged by different results having a direct impact on the life of the population. It was demonstrated that when the standard of living of the population is raised, his attitude, in the matter of birthrate, stretches to go to a controlled procreation; dragging surely a stability or a diminution of the birthrate and surely of a number of the population. The DRC government has done efforts in this sense, pushing him to declare that the country attains, in the matter of population, the level of countries entering in transitional demographic phase, more precisely entering in the first phase of the demographic transition. Knowing that all countries of the world pass by different steps of this schema, the goal of this work is to determine the real level attained by the Congolese populations confirming or annulling authorities’ declarations in this regard. After analyses by using graphical and numerical methods of comparison, we are arrived to the conclusion according to who, the DRC is still in phase meadow-transitional, then efforts must be supplied for the improvement of this situation.
