Answer:
Different methods, such as Gross National Product (GNP) and Gross Domestic Product (GDP) can be employed to assess economic growth. Gross Domestic Product measures the value of goods and services produced by a nation.
Since economic growth is measured as the annual percent change of gross domestic product (GDP), it has all the advantages and drawbacks of that measure. The economic growth-rates of countries are commonly compared using the ratio of the GDP to population (per-capita income).
