Which option gives necessary conditions for reliable growth comparison?

Answer and explanation

Correct answer: Same time period, same definition and clear base population

Direct answer: A. A reliable comparison begins by using the same time period, because a one-year change cannot be fairly compared with a ten-year change without suitable adjustment. Next, the definition must be the same. Total population growth can involve births, deaths and migration, whereas natural increase generally compares births with deaths. Finally, the base population must be clear because a percentage depends on the starting number. A includes all three safeguards. B is wrong because different periods and an unclear base can distort the result. C is wrong because a percentage without its period, definition and denominator lacks meaning. D is wrong because migration may be part of total population growth and should not automatically be removed; it depends on the purpose of the comparison. Memory cue: same period, same meaning, same clear base.
