Maybe it's because of the struggling economy, but Hawaii residents were less satisfied with their standard of living last year, according to new Gallup poll report.

Hawaii's score for a satisfying standard of living—”;all the things you can buy and do”;—dropped more than any other state between 2008 and 2009.

North Dakota topped all states with the highest score for adult satisfaction with their standard of living.

Hawaii remained among states with the highest levels of satisfaction—ranking ninth in the nation—but the satisfaction with living standards slipped 3.6 percent, from 81 percent to 77.4 percent.

“;Despite the many serious economic problems facing the country in 2009—and consumers' resulting pessimism about the economy—the great majority of residents of every state were upbeat about their own standard of living last year,”; according to the report. “;This still left nearly 30 percent of Americans dissatisfied in many states, highlighting the clear need for improvement.”;

Thirty-one states showed an increase in satisfaction of at least one point and five showed a decrease of at least one point, with the greatest decrease in Hawaii.

The least satisfied residents are in Ohio, Michigan, Nevada and Rhode Island.

Gallup's “;State of the States”; report is based on telephone interviews with 353,848 adults aged 18 and older conducted last year between Jan. 2 and Dec. 30.

Last year, Gallup ranked Hawaii as the nation's happiest state in two surveys of Americans' well-being.

In other surveys, Hawaii ranked low in consumer confidence. But last year's polls also show the state's residents still had less stress than residents of the other 49 states.
