What happens if death rate becomes higher than birth rate?

Answer and explanation

Correct answer: Natural increase will be negative

Direct answer: Option B. Natural increase is calculated by comparing births with deaths. In rate form, it is birth rate minus death rate. If the death rate is higher than the birth rate, this subtraction gives a negative result, so natural increase is negative. This means deaths exceed births; the population may decline from natural causes, although migration can alter the final population total. Option A is wrong because rapid growth would require births to exceed deaths, unless a separate large inflow of migrants changes the total. Option B is correct because it describes the sign of natural increase. Option C is wrong because death and birth rates do not guarantee that migration will increase. Option D is wrong because density depends on both population and area and cannot automatically rise when deaths exceed births. Memory cue: birth rate minus death rate—if the second number is larger, the result is negative.
