Final answer:
All statements about the G20 countries are true except the claim that less than half of the world's poor live in the G20 countries, as many G20 countries have large low-income populations.
Step-by-step explanation:
The G20 countries are a significant force in the global economy, but not all statements about them are accurate. Considering the provided data about global income distribution and the world's population shares across different income levels, we can determine the truthfulness of the given statements. More than half of the world's population does live in G20 countries, as both China and India are G20 members and have large populations. It is also true that G20 countries account for over 75% of the world's global trade and generally promote pro-business policies.
However, considering that many populous developing countries with high poverty rates, such as India and China, are part of the G20, and that the majority of the world's poor reside in low- and middle-income countries, it is likely inaccurate to claim that less than half of the world's poor people live in G20 countries. This would point to the statement 'Less than half of the world's poor people live in G20 countries' as being false, given the sizable low-income populations in some G20 countries.
