Final answer:
Mexico is currently experiencing Stage 3 growth in the demographic transition model. If the death rate fell, it would be a continuation of Stage 3 growth.
Step-by-step explanation:
In terms of the demographic transition model, Mexico is currently experiencing Stage 3 growth. In this stage, the birth rate starts to fall, leading to a slowdown in population growth. If the death rate were to fall in this stage, a demographer would describe it as a continuation of Stage 3 growth. The birth rate would still be declining, but the death rate would also be decreasing, resulting in a further slowdown in population growth.
