The official (BEA-inflation-adjusted) GDP grew at an ANNUAL RATE of 1.0% in the 2nd quarter.
http://www.bea.gov/newsreleases/national/gdp/gdpnewsrelease.htmQuoting from the above link: "Real gross domestic product -- the output of goods and services produced by labor and property
located in the United States -- increased at an annual rate of 1.0 percent in the second quarter of 2011 ... FOOTNOTE.--Quarterly estimates are expressed at seasonally adjusted annual rates, unless otherwise specified. "
It did NOT grow 1.0% in the 2nd quarter -- that would be fantastic news if it was true, indicating (if sustained for some more quarters) a good recovery and the dawning of Morning in America and all that. (Instead of a very anemic "recovery" that falls far short of producing enough jobs to keep up with working age population growth) The BEA ALWAYS gives the quarterly numbers as annual growth rates, and likewise that's what the media always reports in my experience. But sometimes, sadly, they leave off the word "RATE".
As for the other number, -3.4%, I suspect it too is an annual rate, in which case this CPI-adjusted GDP declined at an ANNUAL RATE of 3.4% in the 2nd quarter; it did NOT decline 3.4% in the 2nd quarter.
One of my pet peeves is that sometimes some media and talk show hosts are a bit sloppy in reporting economic numbers, confusing a lot of people. I am constantly writing to errant media and talk show hosts when I hear statements like "the economy grew 1% in the 2nd quarter".
