Which two periods are compared to measure population growth?

Answer and explanation

Correct answer: Two different times

Direct answer: Option A is correct. Population growth is a change in the number of people between one time and another. Therefore, we compare population data from an earlier period with data from a later period, such as two census years. The two observations do not have to be from identical dates in every situation, but their dates must be known so that the change and time interval can be understood. Option A gives the required comparison. Option B compares physical water features, not population figures. Option C compares landforms and cannot measure demographic change. Option D compares soil types, which may be useful for other geographical studies but does not measure population growth. Memory cue: population growth is a time-to-time comparison, not a place-feature comparison.
