The world GDP is the sum total of the gross national income for every country in the world. In order to calculate a country's gross national coverage income, it is necessary to measure its GDP. These will be added to the value of the income from imports once they are accumulated. To get the final result, the export value would be subtracted from the result. Additionally, it is essential to keep in mind that GNI and GDP are not the same since the impact of domestic and international trade is reflected.

Once the GNIs of all countries are added together, there will be a balance in the value of both imports and exports. It is important to know that there are 194 economies in the world, with the United States being the largest.

The world's nominal GDP was reported to have reached $80.683.79 billion in 2017. During the following year, world GDP nominally reached $84,835.46 billion. Based on this, the projected nominal GDP for 2019 is $88,081.13 billion. According to the World GDP report of 2018, there was a growth rate of 3.6% for the world economy in 2018.

The World GDP refers to the total economic output of all the countries in the world. This number is measured by adding up all the monetary transactions. It measures how much money changes hands, not what is produced or consumed.

The GDP is the total economic output - and in case we are considering the world GDP, each country's GDP will need to be added up to arrive at the total result. It is thus the total of all value added created by the global economies.

GDP is the total dollar value of all final goods and services produced within a country's borders in a year. The GDP for the world can be calculated by adding up each country's GDP, however this will not be an accurate measurement because countries trade with each other. If one country produces more than it consumes, then there will be imports from other countries to make up for the deficit.

World GDP, or Gross Domestic Product, represents the total monetary value of all goods and services produced across the globe within a specific period, typically a year. It is a key economic indicator used to gauge the overall economic health and productivity of the global economy. World GDP is calculated by summing the GDPs of all countries, usually in terms of a common currency, such as the US dollar, to allow for accurate comparison and aggregation.

World GDP can be measured in two primary ways: nominal GDP and purchasing power parity (PPP). Nominal GDP values goods and services at current market prices, without adjusting for differences in cost of living or inflation. On the other hand, GDP at PPP adjusts for price level differences between countries, offering a more accurate reflection of the relative economic productivity and living standards.

World GDP serves as a benchmark for comparing economic performance over time and across regions. It helps economists, policymakers, and analysts assess trends, identify growth opportunities, and make informed decisions regarding global trade, investment, and development strategies. Additionally, changes in World GDP can signal shifts in the global economic landscape, influencing everything from international trade agreements to geopolitical stability.
