Why is it incomplete to explain causes of population growth only through health improvement?

Answer and explanation

Correct answer: Because birth rate, education, migration and the economy also influence it

Direct answer: A. Health improvement is important because it can reduce deaths, improve survival and affect life expectancy, but population growth is a multi-factor process. Birth rate determines how many people are added through births. Education may influence knowledge, family-size decisions and the timing of marriage or childbearing. Migration changes the population of both the place people leave and the place they enter. Economic conditions affect employment, living standards, family decisions and movement. Therefore a complete explanation must consider several connected factors rather than health alone. B is false because health is strongly related to death rates. C is false because migration can be positive, negative or zero depending on movement. D is false because birth rate is measured using demographic data. A wins because it gives the required broader explanation.
