Sorting is alphabetical by country code, according to ISO 3166-1 alpha-3.

Y = C + I + G + (X − M) Here is a description of each GDP component: C (consumption) is normally the largest GDP component in the economy, consisting of private expenditures in the economy (household final consumption expenditure).
