Concept:The standard of living improves only when national income grows faster than population.
Explanation:National income alone does not measure the welfare of the people.
Effective population control ensures that economic gains are shared among the same or slower-growing number of people.
Without such control, population can grow rapidly and absorb the increase in national income.
Hence, per capita income may not rise and can even fall.
When income is shared among more people, households find it harder to meet basic needs.
This situation directly worsens living conditions and raises the poverty level.
Higher per capita income will not occur because the income per person does not improve.
Thus, the most logical consequence is an increase in poverty.
Answer:B. Increase in poverty.
