A bit dated but I was out of town on the 8th when this came out. The United Bid Committee, Headed by former USSF Pres., Sunil Gulati, an economics professor at Columbia has come up with this heady figure. The 5 billion is expected to boil down to a 3-4 billion after removing public costs with single host locales having $480 million positive. The job total for this time span is hoped to be 40,000 and over 1 billion in worker pay as per this study by The Boston Consulting Group. The first time it will be at 48 teams this the largest soprting event on the planet set these high numbers.
Coming to the figure of 160-620 million in economic activity then translating to a net benefit of approx. 90-480 millioin per city. The three involved nations Canada, Mexico and the final also played in the USA are the largest commercial market in the world bringing with that the opportunity for substantial economic and social benefit to host cities and FIFA alike further advancing global foootball for the foreseeable future.The United Bid hopes to help the new vision of FIFA come to fruition and attach the financial strength of North America to push the game along. WIth modern stadium, infractructure, highly professional management groups and more affords FIFA a never before seen level and best foucus for a successful tourney. The large variance of economic gain is due to cost of living, population, venue capacity and more. There is a lingering effect expected as cities gain first time visitors who would then return soley due to this exposure at the World Cup.
