WASHINGTON (CNN) -- Nearly half of Americans feel the U.S. economy is in a recession, marked by a significant decline in economic activity, according to a survey released Thursday.
The poll by the CNN-Opinion Research Corporation found that while 46 percent of Americans hold that belief, 51 percent don't.
Black citizens were more pessimistic than whites, findings show.
Sixty-nine percent of black Americans feel the United States is in a recession, while only 42 percent of white Americans feel the same way.
The National Bureau of Economic Research defines a recession as "a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP [Gross Domestic Product], real income, employment, industrial production and wholesale-retail sales."
The GDP measures the economy's output. It represents the total market value of all goods and services produced in the United States during a specified period.
According to the bureau, "a recession begins just after the economy reaches a peak of activity, and ends as the economy reaches its trough. Between trough and peak, the economy is in an expansion. Expansion is the normal state of the economy; most recessions are brief and they have been rare in recent decades."
The recession findings may be having an impact on President Bush's approval rating.
The CNN-ORC poll finds Mr. Bush's approval rating remains steady at 36 percent, but his approval rating among black Americans is just 15 percent.
CNN Polling Director Keating Holland says "a majority of whites also disapprove of Bush, although four in 10 have a favorable view of his administration. The president's approval rating has been stuck at 36 percent since late summer."
The sampling error for the survey is plus or minus 3 percentage points for all but the black vs. white breakdowns, which have a sampling error of 5.5 percentage points.
