It is unclear what you mean by "population" in this context. If you are referring to the number of people that work for Forum for the Future, I do not have that information. However, Forum for the Future is a non-profit organization that works with businesses and governments to create a sustainable future.
Copenhagen Institute for Futures Studies's population is 28.
Forum Snowboarding's population is 50.
The population of Forum Communications is 2,500.
The population of Bank Forum is 2,010.
Forum Snowboarding does not have a population as it is a brand specializing in snowboarding products, not a community.
The population of Wireless Innovation Forum is 4.
Pacific Islands Forum's population is 32,500,000.
The population of National Youth Science Forum is 3.
The population of The Parents Circle-Families Forum is 13.
The population of Blandford-Blenheim is 7,149.
They can be. If you look at the futures pricing, you'll see futures contracts that settle in 2013--and futures contracts that settle next month.
You purchase a futures contract by first opening a futures trading account, which is a margin account, with a futures broker. Once that is done, simply choose the specific futures contract you wish to buy and then pay its "Initial Margin", which is a deposit needed to start a futures trade.
