234 years ago the Second Continental Congress adopted the Declaration of Independence announcing the colonies’ separation from Great Britain. It has been estimated that there were approximately 2.5 million people in this new nation at that time. 
Today a celebration of our independence takes place every year on the anniversary of the signing of this document by our founding fathers. Fireworks are a prominent feature of this celebration along with BBQs and gatherings of family and friends. We have grown a bit since gaining our independence – the population for this July 4th is estimated to be 309.6 million.
No doubt you have witnessed the fireworks stands that begin popping up in June in anticipation of this occasion. Many local areas plan events culminating with a fireworks display to the delight of young and old alike. According to the American Pyrotechnics Association we consume more than 200 million pounds of fireworks each year. A surprising 186 million pounds of that consumption is from consumers rather than those used for displays. For 2008 that amounted to revenue of $940 million.
Additional information and resources are available in our guide for the Pyrotechnics Industry.
