Which option shows a data error in comparing growth rates?
Answer and explanation
Correct answer: Directly comparing data from different time periods and definitions
For a valid comparison of growth rates, the data must refer to the same time period and use the same definition. Directly comparing figures from different periods or based on different population definitions can produce a misleading conclusion; therefore, option A shows a data error. Options B and D improve reliability, while option C correctly distinguishes percentage growth from the actual numerical increase. Exam tip: always check the year, area, and definition used before comparing population data.
