Final answer:
Final goods used to compute GDP are the end products consumed by the final user. Intermediate goods and non-essential items are excluded from GDP calculations to avoid double counting.
Step-by-step explanation:
GDP refers to the current value of all final goods and services produced in a nation in a year. Final goods are goods at the furthest stage of production at the end of a year. They are the end products consumed by the final user. To compute GDP, government statisticians exclude intermediate goods, which are goods that go into producing other goods, and non-essential items that are excluded from GDP calculations. This is done to avoid double counting and to accurately measure the value of goods and services produced in the economy.
