Final answer:
To appreciate NCDG, one must comprehend a range of indicators, including social indicators like literacy rate and life expectancy, and economic indicators like GDP per capita. These indicators help to assess a nation's development level and standard of living.
Step-by-step explanation:
To fully understand the NCDG (which may refer to a concept such as the Non-Communicable Disease Global Monitoring Framework, though it's not explicitly defined in the provided context), one needs knowledge of various levels of indicators, like social, economic, and demographic indicators. Social indicators include literacy rate, life expectancy, and infant mortality rate. These metrics tell us about the education levels, health outcomes, and conditions for children in a nation, reflecting its social development.
Economic indicators provide data on a country's economic growth and development, critical in making informed decisions regarding trade, military, politics, and diplomacy. Among these are the gross domestic product per capita that depicts the average economic output per person, signaling the country's wealth and productivity levels.
By analyzing such indicators, we can use frameworks like the Human Development Index to categorize countries as less developed, newly industrialized, or more developed, assessing their standard of living and overall development.
