Wisconsin ecomomic growth was among the lowest among the fifty states last year. That's according to statistics released Thursday by the U-S Bureau of Economic Analysis , which show Wisconsin's gross domestic product was $232 billion in 2007 – just one-percent more than the year previous. That was the 39th slowest economic growth among the 50 states, and only half the national growth average of two-percent. Michigan and New Hampshire were the only states where the economy declined last year. Michigan's gross domestic product fell 1.2 percent. Utah had the nation's fastest GDP growth, at just over 5 percent. GDP is an inflation–adjusted measure of each state's production, wherever sold. It is not a measure of the prices of goods and services sold in each state.
