Final answer:
Without the GDP per capita, we cannot calculate the population from the given GDP figures of 2014 and 2015. Real GDP is a key economic measure and, along with GDP per capita, it provides an insight into a country's economy and standard of living.
Step-by-step explanation:
The question pertains to a country's real GDP and its population. However, to calculate the population based on real GDP, additional information is needed, such as the GDP per capita (the GDP divided by the population). In the data provided, though, there is no direct information regarding the population for the given GDP figures of 250 billion in 2014 and 265 billion in 2015. Without the GDP per capita or a similar statistic, it is impossible to determine the population of the nation in question.
Real GDP is a crucial economic indicator that represents the value of all goods and services produced by a nation, adjusted for inflation. The vast size of the U.S. economy in terms of GDP showcases the production levels of goods and services. Additionally, GDP per capita is a helpful measure in estimating a nation's standard of living. It is important to note that these economic indicators are foundational for understanding other aspects of economics such as unemployment, inflation, or interest rates.
