The growth of a country’s population is affected by

Step 1: Analyze the question We are asked what affects the growth of a country's population. Population growth is a demographic concept, so we look for the option that relates to demographic factors.

Step 2: The concept Population growth depends on:

• Birth rate (number of births per 1,000 people)
• Death rate (number of deaths per 1,000 people)
• Net migration (immigration minus emigration)

The natural increase is: Birth rate − Death rate. Migration then adds or subtracts from this.

Step 3: Evaluate each option

• A. Military might: This has no direct effect on how many people are born or die. Not a determinant.
• B. Number of births per thousand of the population: This is the birth rate, a direct determinant of population growth. ✔
• C. Number of people willing to be counted: This affects the accuracy of a census, not the actual growth of the population.
• D. Amount of money in circulation: This is a monetary matter (inflation, money supply), not a demographic one.
• E. Number of men in the population: The sex composition matters less. Growth depends more on the number of women of child-bearing age and on fertility rates, not simply the number of men.

Step 4: Answer

Tip: For population questions, remember the formula Growth = (Births − Deaths) + (Immigrants − Emigrants). Any option that mentions birth rate, death rate, or migration is usually the right one. Be careful not to confuse census accuracy (C) with actual population growth.
