Which statement about global population trends is true?

• A. Most of the world's population growth occurs in developing countries
• B. Most growth occurs in developed countries
• C. Growth is evenly distributed
• D. Growth is influenced by climate policy

Answer: (A)

Global population growth reflects differences in fertility rates and age structure across regions. In developing countries, fertility rates remain higher and the population is younger, so more births occur each year. As mortality declines, those births translate into rapid overall growth, contributing a large share of new people from regions like Sub-Saharan Africa and parts of Asia. In contrast, many developed countries have fertility around or below replacement level and aging populations, leading to slower growth or even decline, so they contribute less to global population increases. Climate policy is not the main factor shaping how many people are being born; the trend is driven by natural fertility and demographic age structure, along with development factors that influence family size. That combination explains why most of the world’s population growth occurs in developing countries.
