Focus on Economic Data: U.S. Real GDP Growth, February 28, 2013
This lesson printed from:
This lesson focuses on the February 28, 2013, second estimate of U.S. real gross domestic product (real GDP) growth for the fourth quarter (Q4) of 2012, as reported by the U.S. Bureau of Economic Analysis (BEA). The current data and historical data are explained. The meaning of GDP and potential impacts of changes of GDP are explored. This lesson will also raise questions about the impact of the current level of growth on the U.S. economy and individuals.
- Determine the current and historical growth of U.S. real gross domestic product.
- Identify the components of the measurement of the nation's gross domestic product.
- Assess the relationship of real GDP data, the indexes of economic indicators, and business cycles.
- Speculate about the nature and impact of current economic conditions and implications for the future.
Good News! Bad News!
The good news: The second estimate of U.S. real GDP growth in the fourth quarter of 2012 was a complete reversal of the negative first estimate.
The bad news: The first estimate was a 0.1 percent decrease on real GDP and the second estimate was just a 0.1 percent increase. A reversal yes, but not much!
On February 28, 2013, the U.S. Bureau of Economic Analysis announced the second estimate of U.S. real gross domestic product growth for the fourth quarter (October-December) of 2012.
National Income and Product Accounts
Gross Domestic Product, 4th quarter 2012 and annual 2012 (second estimate)
Released: February 28, 2013
"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 0.1 percent in the fourth quarter of 2012 (that is, from the third quarter to the fourth quarter), according to the "second" estimate released by the Bureau of Economic Analysis. In the third quarter, real GDP increased 3.1 percent."
Note: Unless otherwise cited, the quoted sections of this lesson are from the BEA's February 28, 2013, "Gross Domestic Product, 4th quarter 2012 and annual 2012" announcement. www.bea.gov/newsreleases/national/gdp/gdpnewsrelease.htm
The BEA explained the change from the first to the second estimate.
"The GDP estimate released today is based on more complete source data than were available for the "advance" estimate issued last month. In the advance estimate, real GDP declined 0.1 percent. The upward revision to the percent change in real GDP is smaller than the average revision from the advance to second estimate of 0.5 percentage point. While today’s release has revised the direction of change in real GDP, the general picture of the economy for the fourth quarter remains largely the same as what was presented last month."
In other words, the estimate of GDP, whether it is negative 0.1 percent or positive 0.1 percent is still not very good, and the growth of the U.S. economy seems to be weakening. The Q3 2013 final estimate of real GDP growth was 3.1 percent growth.
Students: What could be the consequences of such slow GDP growth?
Read the entire text of the February 28, 2013, BEA announcement to learn more details about recent U.S. real GDP growth. Remember, the BEA releases the estimate for each quarter three times. This was the second estimate for Q4 2012. The first estimate for Q4 2012 was a growth rate of - 0.1 percent. This was an upward revision of the initial Q4 2013 real GDP growth rate.

Was the First GDP Estimate for Q4 2013 “Wrong”?
Where was the GDP growth in Q4 2012?
"The increase (change in size) in real GDP in the fourth quarter primarily reflected positive contributions from personal consumption expenditures (PCE), nonresidential fixed investment, and residential fixed investment that were partly offset by negative contributions from private inventory investment, federal government spending, exports, and state and local government spending. Imports, which are a subtraction in the calculation of GDP, decreased."
"The deceleration (slowing of the growth rate) in real GDP in the fourth quarter primarily reflected downturns in private inventory investment, in federal government spending, in exports, and in state and local government spending that were partly offset by an upturn in nonresidential fixed investment, a larger decrease in imports, and an acceleration in PCE."
Figure 1, below, shows graphically the U.S. quarterly real GDP growth rates from 1999 through Q4 2012. Note the real GDP negative growth in late 2008 and early 2009. This is the period that looks like the traditional definition of a recession. According to the National Bureau of Economic Research (NBER), the recession began in December, 2007, and ended in June, 2009 (www.nber.org/cycles.html
Remember, the formula to determine GDP (Y) is to add personal consumption expenditures (C), net private investment (I), government spending (G) and Net exports (X).
C + I + G + X = Y

The BEA breaks down the quarterly growth or decline by sector - personal consumption expenditures (PCE), private investment, government spending, and net exports. Recently, the BEA has highlighted the levels of inventories as factors in determining real GDP growth.
Students: What sectors declined in Q4 2012. What sectors grew in Q2 2012? Any surprises?
The BEA also breaks down the GDP data by sectors. Go to www.bea.gov/newsreleases/national/gdp/2012/pdf/gdp4q11_2nd.pdf . Scroll down the announcement to the "Tables" to see recent sector and industry group GDP data.

What was the current-dollar GDP in Q4 2012?
"Current-dollar GDP -- the market value of the nation's output of goods and services -- increased 1.0 percent, or $40.2 billion, in the fourth quarter to a level of $15,851.2 billion. In the third quarter, current-dollar GDP increased 5.9 percent, or $225.4 billion.
Remember, $15,851.2 billion is the same as $15.8512 trillion.
According to the U.S. Census Bureau, the U.S. resident population at the end of 2012 was 315,090,923. (www.census.gov/popest/data/national/totals/2012/index.html ). Given those estimates, the U.S. current dollar per capita real GDP was approximately $50,307. Per capita GDP is the total GDP divided by the population.
Current dollar GDP in Q4 2013 was $15,851,200,000, and real GDP (adjusted for inflation) was $13,656,800,000. This tells us that almost $2.2 trillion of the nominal growth since 1983-85 has resulted from an increase in the price level (inflation). The rest was real or constant dollar growth.
Students are you clear about the difference between the nominal (current dollar) GDP and the real (chained dollar) GDP measurements?
Students: To compare the U.S. per capita GDP with the per capita GDPs of other nations, see the CIA World Factbook, www.cia.gov/library/publications/the-world-factbook/rankorder/2004rank.html . Remember, a high per capita GDP doesn't necessarily mean that all people in a country have high incomes or a high standard of living. In many instances, GDP figures for a nation do not accurately reflect the well-being of all individuals in that nation. If purchasing power varies among nations, the term “purchasing power parity” (PPP) is used to reflect economic data that has been adjusted by varying national price levels.
Annual GDP Estimate Revisions
According to the BEA annual revisions to GDP estimates are made each year in order to:
- Incorporate most complete and reliable source data.
- Provide a more detailed picture of the economy.
- Make improvements to methods used for preparing the estimates.
Figure 2, below, shows the U.S. current dollar and real GDP for the years 2000 through 2012. Note the years when the GDP adjustment was significant and when the adjustment was small (compare the difference between the growth of the nominal and real GDP numbers.
Quarterly GDP data is seasonally adjusted to remove variations that normally occur at about the same time and in about the same magnitude each year—for example, weather, holidays, and tax payment dates. After seasonal adjustment, cyclical and other short-term changes in the economy stand out more clearly. Annual data is not seasonally adjusted.
The Bureau of Economic Analysis (BEA), an agency of the U.S. Department of Commerce, “prepares national, regional, industry, and international accounts that present essential information on such key issues as economic growth, regional economic development, inter-industry relationships, and the Nation's position in the world economy.” Source: BEA Mission Statement
[Note to teachers: NIPAs (national income and product accounts) are the BEA's economic measurements that “display the value and composition of national output and the distribution of incomes generated in its production.” Source: BEA Glossary ]
2012 Annual GDP Data
"Real GDP increased 2.2 percent in 2012 (that is, from the 2011 annual level to the 2012 annual level), compared with an increase of 1.8 percent in 2011."
Note; The annual GDP figure differs slightly from the figure for Q4. The annual figure is the amount of the change over the past 12 months. The quarterly (three month period) amounts or changes during that 12 month period may have differed greatly. Thus, the annual change may differ from the change reported for the end of the fourth quarter.
"The increase (dollar value) in real GDP in 2012 primarily reflected positive contributions from personal consumption expenditures (PCE), nonresidential fixed investment, exports, residential fixed investment, and private inventory investment that were partly offset by negative contributions from federal government spending and from state and local government spending. Imports, which are a subtraction in the calculation of GDP, increased."
"The acceleration (rate of change) in real GDP in 2012 primarily reflected a deceleration in imports, upturns in residential fixed investment and in private inventory investment and smaller decreases in state and local government spending and in federal government spending that were partly offset by decelerations in PCE, exports, and nonresidential fixed investment."
Be careful not to look at one quarterly increase or decrease and identify it as a trend. Although private investment increased just slightly in Q4, any of the four sectors may have been affected by one-time ot transient events.
"Current-dollar GDP increased 4.0 percent, or $605.8 billion, in 2012 to a level of $15,681.5 billion, compared with an increase of 4.0 percent, or $576.8 billion, in 2011."
Students: How do you feel about the health of the U.S economy? Is it getting better? Worse? Is such low GDP growth enough when 12 million Americans are still unemployed and many more are underemployed?
The U.S. real GDP growth rate dropped to just 0.1 percent in Q4 2012, according to the Bureua of Economic Analysis second estimate. This was a significant slow-down from the Q3 growth rate of 3.1 pecent.
In Q3, the U.S. economy was growing at a modest – almost an average - pace. Unfortunately, this growth had not resulted in the creation of enough new jobs to reduce the unemployment rate to anywhere near a normal level. The U.S. unemployment rate remains at over 8 percent). With a slower growqth rate in Q4, the prospects for significant job creation seem negative.
It is generally clear that if unemployment is high, the economy will not be producing at its full or normal output. Since people who are not working, their labor resources are not being used effectively. What is the relationship between unemployment and output?
In 1962, economist Arthur Okun theorized that there is a predictable relationship between unemployment and national output (GDP). Okun's Law correlates changes in real GDP and changes in the unemployment rate. He said that real GDP grows at about 3% per year when unemployment is normal.
For every point above 3.0 percent unemployment, the nation’s GDP decreases by 2%. And, it also works in reverse – each percentage point under 3.0 results in an additional 2 percent in GDP growth. For example, if the U.S. unemployment rate is 9.0 percent, 6.0 percent over the 3.0 average, GDP is reduced by 12 percent.
Many suggest that this historic relationship between unemployment and the “GDP gap” no longer exists – at least to the degree that Professor Okun suggested. The economy grew at a greater rate in late 2009, despite an even higher unemployment rate. The new concept is the “jobless recovery,” made possible by technology and greatly improved productivity.
Are we in a "new economy," one where the relationship between employment and output has changed?
Keep an eye on the employment and GDP data in the coming months.
The U.S. Central Intelligence Agency (CIA) “World Factbook” ranks the nations of the by various economic measures, including gross domestic product. The largest fifteen nations by GDP are listed below (rankings as of 2012).
Note: A nation's GDP at purchasing power parity (PPP) exchange rates is the sum value of all goods and services produced in the country valued at prices prevailing in the United States in the year noted. All figures are equated to U.S. dollars for comparison purposes.
In terms of total size of GDP, the U.S. ranks second, just behind the European Union nations’ total. (Estimates are for year 2011). See the CIA "Guide to Country Comparisons " webpage.
