Answer:
The population is not big if both the birthrate and death rate is high.
Explanation:
High birthrate and high death rate are characteristics of the first stage of the demographic transition model. The population in this stage leaves in a primitive manner. The education and literacy rates are low, water and food are scarce and of low quality, healthcare is something unheard of for the majority, and the ifrastructure is in terrible condition. The end result is a population that grows very slowly or stagnates.
With all living conditions being on a very low level, the death among infants and women during delivery or shortly after is on a very high level. Also, life expectancy is very low. Outbreaks of diseases are very common and have devastating effects. Even though the birthrate is high, it is simply not capable to overcome the very high death rate, so the population's growth is very slow, close to zero. Countries that fall into this category are Chad, CAR, Burundi, Cambodia, Laos, etc.
