If two countries begin with the same population, which country's population will double first?

Answer and explanation

Correct answer: The one with the higher growth rate

When two countries start with the same population, the important difference for doubling time is their growth rate. A growth rate shows the proportion by which population increases during a period. A higher rate adds a larger fraction of the starting population each period, so the population reaches twice its original size sooner.

For example, with equal starting populations, a country growing at 4% per year will double sooner than one growing at 2% per year, assuming comparable conditions. Therefore, option A is correct. Area and the number of mountains may affect settlement patterns, but they do not by themselves determine which equal-sized population doubles first.
