Answer:
The best answer for the question: Which of the following statements is true, I would say is: Mexico has a lower standard of living than China.
Explanation:
The reason comes from looking at the data and realizing that, although the GDP per capita in Mexico is much higher than that of China, all other indicators, especially that of poverty, and that of crime rate, are much lower in China, than Mexico, even with the population difference between the two coutries. Also, statistically speaking, the difference in Avg. life expectancy between the two nations is really small. This means that overall, China, even with lower GDP per capita, is being able to distribute wealth better, and their policies are improving the living standards of their citizens, especially when seeing the really low level of poverty percentage, which is the lowerst for all the countries being compared. This is a great indicator that living conditions for Chinese, at the moment, are better than for Mexicans, and that is why the answer is the last one.
