How does health improvement work as a cause of population growth?

Answer and explanation

Correct answer: By reducing the death rate

Direct answer: Option A is correct. Improvements in healthcare, sanitation, disease prevention, nutrition and access to treatment can reduce deaths, especially deaths that could have been prevented. When the death rate falls while births continue, more people survive and the population may grow through natural increase. This does not mean health improvement is the only cause of population growth; births, migration, age structure and other conditions also matter. Option B is wrong because increasing land area does not directly create more people. Option C is wrong because removing a census only removes or weakens measurement; it does not change the actual population. Option D concerns soil and is not the demographic mechanism asked about. Memory cue: better health mainly increases survival by reducing mortality.
