What is known from the difference between birth rate and death rate?

Answer and explanation

Correct answer: Natural increase

Direct answer: A, natural increase. Birth rate tells us how many live births occur in a population, while death rate tells us how many deaths occur. When the death rate is subtracted from the birth rate, the result is the natural increase rate. It shows the change caused only by births and deaths, without counting people entering or leaving through migration. Option B is wrong because density means population divided by area. Option C is wrong because the difference between these rates does not measure land area. Option D is wrong because language diversity concerns the variety of languages, not demographic change. Memory cue: births add, deaths subtract; birth rate minus death rate equals natural increase.
