If a district boundary has changed, what caution is necessary when comparing population growth?

Answer and explanation

Correct answer: A boundary change can alter the base area and population

Correct answer: A. A population comparison is meaningful only when the areas being compared are comparable. If a district boundary changes, people or villages may be added to or removed from the district. The recorded population may therefore change partly because of administration, not because of births, deaths or migration. Option A is correct because the boundary change can alter both the base population and the territorial unit. Option B is wrong because boundary changes can affect the data. Option C is absurd and has no demographic basis. Option D is wrong because population growth depends on demographic processes and migration, not only weather. To make a fair comparison, use adjusted figures for the same boundaries or clearly note the boundary change. Memory cue: before comparing growth, compare the map as well as the numbers.
