The table above shows the total amount of wood produced in the United States from 1975 to 1989.  The figures are in millions of board feet, and include both softwoods and hardwoods.

The total amount of wood produced has varied considerably over the years.  Though low in the early 1980s, it rose in the latter part of the decade.

One cause of the changing level of wood production is the fact that wood is produced and sold around the world.  As the world price of wood fluctuates, lumber production becomes more or less profitable for producers in the US.
