The countries mentioned in the question - the United States, Canada, Northern and Western Europe - have already undergone the first two stages of the demographic transition (high birth rates and high death rates, followed by high birth rates and low death rates). They are now in the third stage, characterized by lower birth rates and relatively stable population growth. Therefore, option D is the best answer. Option A is incorrect because these countries have already progressed beyond the first stage. Option B is incorrect because these countries are not trying to curb population growth - in fact, many are experiencing population decline due to low birth rates. Option C is incorrect because these countries are not threatened by underpopulation, but rather facing the consequences of an aging population and low birth rates.
