Final answer:
A higher literacy rate in countries is linked to a higher standard of living due to better healthcare, lower birth rates, and greater economic productivity.
Step-by-step explanation:
Based on the information provided, a conclusion that can be made is that countries with a higher literacy rate tend to have a higher standard of living. This is because higher literacy rates are commonly associated with high quality healthcare, lower birth rates, and greater economic productivity, which together contribute to a higher gross domestic product (GDP) and GDP per capita.
This implies that a nation's investment in human capital, like education, leads to a stronger and healthier economy and social well-being.
