This lesson focuses on the December 22, 2011, third (final) estimate of U.S. real gross domestic product (real GDP) growth for the third quarter (Q3) of 2011, 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.

Current Key Economic Indicatorsas of May 5, 2013
On a seasonally adjusted basis, the Consumer Price Index for All Urban Consumers decreased 0.2 percent in March after increasing 0.7 percent in February. The index for all items less food and energy rose 0.1 percent in March after rising 0.2 percent in February.
Total nonfarm payroll employment rose by 165,000 in April, and the unemployment rate was little changed at 7.5 percent. Employment increased in professional and business services, food services and drinking places, retail trade, and health care.
Real gross domestic product increased at an annual rate of 2.5 percent in the first quarter of 2013 (that is, from the fourth quarter to the first quarter), according to the "advance" estimate released by the Bureau of Economic Analysis. In the fourth quarter, real GDP increased 0.4 percent.
To support continued progress toward maximum employment and price stability, the Committee expects that a highly accommodative stance of monetary policy will remain appropriate for a considerable time after the asset purchase program ends and the economic recovery strengthens. In particular, the Committee decided to keep the target range for the federal funds rate at 0 to 1/4 percent and currently anticipates that this exceptionally low range for the federal funds rate will be appropriate at least as long as the unemployment rate remains above 6-1/2 percent...
Each month, the Bureau of Economic Analysis (BEA), an agency of the U.S. Department of Commerce, releases an estimate of the level and growth rate of U.S. gross domestic product (GDP), the output of goods and services produced by labor and property located in the United States.
This lesson focuses on the BEA's third (final) estimate of real GDP growth released on December 22, 2011, for the third quarter (Q3) of 2011 (July-September). Understanding the level and rate of growth of the economy's output (GDP) helps to better understand growth, employment trends, the health of the business sector, and consumer well-being.
[Note to teachers: During the first semester of the 2011-2012 school year (September-December), EconEdLink will publish five Focus on Economic Data lessons on "U.S. Real GDP Growth." Real GDP data is announced three times for each fiscal quarter. For Q3 2011, the first estimate was made in October. The second estimate was made in November. And, the third estimate for Q3 is made in December (this lesson).]
[NOTE: GDP data reports lag the reporting period - the fiscal quarter. The current estimate is the final estimate for Q3 2011 (July-September). Each of the three estimates for a quarter will include more comprehensive data and may modify the growth rate reported earlier].
[NOTE: The BEA previously used the terms "advance, preliminary and final" to identify the three quarterly real GDP estimates. The terms "first, second and third" have replaced the previous announcement language.]
Each Real GDP lesson in a semester will provide the most up-to-date data and focus on some specific topics or issues related to GDP:
- August (second estimate for Q2 2011): How to read the data, real vs. nominal, and how the data is collected
- September (third estimate for Q2 2011): Factors influencing the change in GDP, revisions, and seasonal adjustment
- October (first estimate for Q3 2011): Business cycles and indicators of future growth (decline)
- November (second estimate for Q3 2011): More details of U.S. GDP growth.
- December (third estimate for Q3 2011): Year-end summary, connections to other macroeconomic data, and U.S. regional comparisons.

Key Economic Indicatorsas of December 22, 2011
On a seasonally adjusted basis, the Consumer Price Index for All Urban Consumers was unchanged in November after decreasing 0.1 percent in October. The index for all items less food and energy rose 0.2 percent in November after increasing 0.1 percent in October.
The unemployment rate fell by 0.4 percentage point to 8.6 percent in November, and nonfarm payroll employment rose by 120,000. Employment continued to trend up in retail trade, leisure and hospitality, professional and business services, and health care. Government employment continued to trend down.
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 1.8 percent in the third quarter of 2011 (that is, from the second quarter to the third quarter), according to the "third" estimate released by the Bureau of Economic Analysis. In the second quarter, real GDP increased 1.3 percent.
The FOMC decided to keep the target range for the federal funds rate at 0 to 1/4 percent and currently anticipates that economic conditions--including low rates of resource utilization and a subdued outlook for inflation over the medium run--are likely to warrant exceptionally low levels for the federal funds rate at least through mid-2013.
The U.S. economy continues to grow slowly, according to the latest estimate of real GDP growth by the Bureau of Economic Analysis. Despite the hundreds of billions of dollars of economic stimulus spending and Federal Reserve policies to keep interest rates very low, the economy's output remains below the desired level and unemployment remains very high, at 8.6 percent in November.
Take a look at the most recent estimate of U.S. real GDP growth to better understand the pattern of growth in the economy and how the current conditions impact you and others.
U.S. Bureau of Economic Analysis
National Income and Product Accounts
Gross Domestic Product, 3rd quarter 2011 (third estimate)
Released December 22, 2011
"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 1.8 percent in the third quarter of 2011 (that is, from the second quarter to the third quarter), according to the "third" estimate released by the Bureau of Economic Analysis. In the second quarter, real GDP increased 1.3 percent."
Real GDP growth has improved slowly since the second quarter, but still not enough to put the millions of unemployed workers back on the payrolls. Congress and the Obama administration continue to debate proposals to further stimulate the economy, including extensions of tax cuts that are set to expire.
This estimate of Q3 growth is further evidence that some additional monetary and/or fiscal policy actions may be needed. The third estimate of 1.8 percent growth was less than the previous Q3 estimate of 2.0 percent growth made in November. Remember, each quarterly estimate is made three times over three months. Each estimate is based on more complete, revised, or new data.
"The GDP estimate released today is based on more complete source data than were available for the "second" estimate issued last month. In the second estimate, the increase in real GDP was 2.0 percent."
[Teacher Note: Ask students: What do you think should be done to help the economy grow? This is a good time to remind students about fiscal policies (taxes and spending) and monetary policies (Federal Reserve policies to influence interest rates and the money supply). Students should be able to explain how policies that increase spending and borrowing are intended to stimulate the economy.]
Where did the Q3 Growth Come From?
"The increase in real GDP in the third quarter primarily reflected positive contributions from nonresidential fixed investment, personal consumption expenditures (PCE), exports, and federal government spending that were partly offset by negative contributions from private inventory investment and state and local government spending. Imports, which are a subtraction in the calculation of GDP, increased."
"The acceleration in real GDP in the third quarter primarily reflected accelerations in PCE, in nonresidential fixed investment, and in exports, and a smaller decrease in state and local government spending that were partly offset by a larger decrease in private inventory investment."
Key Industries - Computers and Motor Vehicles
"Final sales of computers added 0.22 percentage point to the third-quarter change in real GDP after adding 0.07 percentage point to the second-quarter change. Motor vehicle output added 0.12 percentage point to the third-quarter change in real GDP after subtracting 0.10 percentage point from the second-quarter change."
[Teacher Note: This is an opportunity to teach about the role of business investment in future production. Ask: How should businesses use their profits? Capital investment? Hiring new workers? Lowering prices? This may provoke an interesting discussion.]
[Teacher Note: Ask students why they think the BEA specifically mentions motor vehicle and computer sales. These are key industries indicating both business investment and consumer spending growth. According to the BEA, these are the industries that are most requested by data users.]
Growth by Sector
"Real personal consumption expenditures increased 1.7 percent in the third quarter, compared with an increase of 0.7 percent in the second. Durable goods increased 5.7 percent, in contrast to a decrease of 5.3 percent. Nondurable goods decreased 0.5 percent, in contrast to an increase of 0.2 percent. Services increased 1.9 percent, the same increase as in the second." Consumers are increasing their spending. Consumer spending is usually about 70 percent of the nation's GDP.
"Real nonresidential fixed investment increased 15.7 percent, compared with an increase of 10.3 percent. Nonresidential structures increased 14.4 percent, compared with an increase of 22.6 percent. Equipment and software increased 16.2 percent, compared with an increase of 6.2 percent. Real residential fixed investment increased 1.3 percent, compared with an increase of 4.2 percent."
[Teacher Note: Investment is a key to future growth. During the recession, investment fell considerably. Ask students why investment is so critical to future growth. Investment in real capital - buildings, tools and equipment may indicate future hiring.]
"Real exports of goods and services increased 4.7 percent in the third quarter, compared with an increase of 3.6 percent in the second. Real imports of goods and services increased 1.2 percent, compared with an increase of 1.4 percent."
"Real federal government consumption expenditures and gross investment increased 2.1 percent in the third quarter, compared with an increase of 1.9 percent in the second. National defense increased 5.0 percent, compared with an increase of 7.0 percent. Nondefense decreased 3.8 percent, compared with a decrease of 7.6 percent. Real state and local government consumption expenditures and gross investment decreased 1.6 percent, compared with a decrease of 2.8 percent."
"The change in real private inventories subtracted 1.35 percentage points from the third-quarter change in real GDP, after subtracting 0.28 percentage point from the second-quarter change. Private businesses decreased inventories $2.0 billion in the third quarter, following increases of $39.1 billion in the second quarter and $49.1 billion in the first."

Recent Real GDP Growth
The history of real GDP growth over the past several years, Figure 1, below, shows the business cycles of expansion, peak, decline and trough. Note the period of late 2008 and early 2009, the most recent recession. The National Bureau of Economic Research (NBER) announced that the recession began (a peak in the business cycle) in December, 2007, and ended (a trough in the business cycle) in June, 2009.
[Teacher Note: Take this opportunity to reinforce student understanding of business cycles. For information about business cycles, go to the National Bureau of Economic Research (NBER) website: http://www.nber.org/cycles/main.html . Ask students to identify the recent recessions.]
Figure 2, below, shows the current dollar and constant dollar figures for U.S. gross domestic product for the past decade. Note that the both constant dollar and real GDP decreased from 2008 to 2009 – the recession. Also notice the long period of steady economic expansion between the years 2000 and 2008, leading up to the recession.
Compare the dollar measurements in Figure 2 with the graph in Figure 1 to see how the graphic representation of GDP growth was determined. Note: The graph shows only real GDP.
[Teacher Note: Make sure students understand the difference between nominal (current-dollar) and real (constant or chained dollar) GDP measurements. The Current-dollar estimate is the market value of an item. It reflects prices and quantities of the period being measured. The chained-dollar estimate is calculated by taking the current-dollar estimate and adjusting it for inflation using the chained-type quantity index number.]
GDP vs. GNP
You may hear references to gross national product (GNP) and gross domestic product (GDP). What is the difference?
The U.S. current-dollar GDP in Q3 2011 (annualized) was $15,176.1 billion. When adjusted for inflation in chained 2005 dollars, the real Q3 annualized GDP was $13,278.5. Current-dollar GDP increased 4.4 percent, or $163.3 billion, in Q3 2011, after increasing 4.0 percent, or $145.0 billion in Q2.”
Note: Prior to 1991, the BEA used gross national product (GNP) as the primary measurement of production output. The difference is that GDP is a measurement of production within a country's borders and GNP is a measurement of production by enterprises owned by a country's citizens. Production within a country's borders, but by an enterprise owned by someone from outside the country, counts as part of the country’s GDP. The BEA switched to GDP primarily because most of the other developed nations used GDP at that time, and it made international production output comparisons easier.
Figure 3, below, shows the primary (National Product and Income Accounts (NIPA) components of U.S. national income, gross national product and gross domestic product for Q3 2011. Note that the largest component of GDP, by far, is employee compensation (salaries and wages).
Measuring National Income, GNP, and GDP:GDP and Other Macroeconomic Data
It is sometimes instructive to find relationships between various macroeconomic data. These relationships may sometimes give us a broader picture of the economy. For instance, there is a general relationship between output (GDP) and employment. As GDP increases, employment tends to increase. In the past several months, as real GDP has decreased, the unemployment rate has increased. One piece of data confirms the meaning of the other.
Figure 4 illustrates four sets of macroeconomic data - CPI, unemployment, real GDP growth and the federal funds rate. Notice the long term relationship of periods of output growth and decline with the changes in the unemployment rate. This relationship makes sense as the number of employed is directly related to output. Some increase in output can be attributed to improvements in productivity, but growth is very much dependent on labor force growth and employment. In late 2008 and 2009, as U.S. real GDP declined, the unemployment rate increased substantially.
Business cycles or periodic fluctuations in growth and employment illustrate the relationships of some data (see Figure 3). When the National Bureau of Economic Research (NBER) tracks cycles in order to identify recessions, they use the combination of employment, GDP growth and other factors. How do consumer prices fit into this analysis? The NBER uses real GDP growth and real personal income as primary factors identifying business cycles. Using employment and income data adjusted for inflation allows the NBER to make more accurate comparisons from one data period to the next.
[Teacher Note: This is another good opportunity to use the business cycle to illustrate the growth pattern of the U.S. economy over the past couple of years - expansion, peak, contraction, and trough. Are we still in a "trough" despite the NBER announcement of the end of the recession?]
Inflation and GDP
Accurate measurement of gross domestic product or GDP growth is also dependent on the accurate measurement of inflation. A rise in the price level "inflates" the measurement of GDP growth - miscalculating real growth in the economy. A more meaningful measurement of the growth of output is real GDP - the nominal GDP measurement adjusted for the impact of inflation. Although CPI is the most common measurement of inflation for many uses, the adjustment of GDP uses a process based on the GDP deflator. Both the CPI and the GDP deflator are measurements of average prices, but the GDP deflator includes all of the goods and services produced in the economy, not just the CPI market basket.
CPI vs. GDP Deflator as Measures of Inflation
The rate of inflation rate determined by the CPI and GDP deflator are normally quite similar. Since the CPI uses a fixed market basket of goods and services, it assumes a fairly constant pattern of consumer purchases. Over time, the market basket may be changed, based on changes in consumer behavior. The GDP deflator uses a flexible basket of goods and services based on the actual quantities of goods and services produced in a year, while the prices of the goods and services are fixed. The GDP deflator uses a much larger quantity of goods and services.
The CPI does not take into account substitution - the tendency of consumers to choose lower priced goods in place of more expensive ones. Just the opposite sometimes happens, as consumers may choose to purchase more expensive goods as their incomes increase. The GDP deflator can take these substitutions into account. Because the GDP deflator assumes substitutions, it may underestimate the impact of inflation when consumers do not (are not able to) substitute. The CPI may overestimate the impact of inflation when consumers do substitute.
Most government agencies and many private contracts use the CPI to determine a cost of living adjustments (COLA). The Social Security Administration added a 5.8 percent COLA to Social Security benefits and SSI payments in January 2009, based on the percentage increase in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter of 2007 to the third quarter of 2008. If there had been no increase in the CPI in that time period, there would have been no increase in benefits.
Inflation and Unemployment
Long-standing economic theory had assumed that there is a predictable trade-off between the impact of public policy decisions and economic change on inflation and unemployment. This theory, developed by New Zealand Economist William Phillips in 1958, was based on his observation of an inverse relationship between money wage changes (inflation) and unemployment in the British economy over a period of time. The "Phillips Curve" proposed that when unemployment is low, inflation tends to be high and when unemployment is high, inflation tends to be low.
The implication for policy makers was that "Keynesian" policies could be used to control unemployment and inflation. Increased spending can lower unemployment with the risk of a high rate of inflation. Policy makers face the Phillips Curve trade-off. Today, policy makers who propose to use monetary policy (lower interest rates) or fiscal policy (deficit spending) to stimulate the economy, and increase GDP and employment, are aware of its potential inflationary effect. The Phillips Cure theory lost favor in the late 1980s when there were periods of both high unemployment and high inflation, followed in the 1990s by periods of low unemployment and low inflation.
The Federal Reserve recognized this potential trade-off in its most recent monetary policy statement when it justified an aggressive stimulatory policy by saying that the current conditions did not include an inflationary threat. Low inflation provides room for aggressive policies to stimulate the economy. Should inflation become a real threat, the Fed may slow down growth of the money supply.
[Teacher Note: Ask: Does the Phillips Curve make sense? Does it apply in this period of time?]
Look again at the data in Figure 4 about the recent performance of the U.S. economy. Notice the relationships of real GDP growth, payroll employment (the NBER's key data) and the unemployment rate. CPI data has been included because it is also the subject of monthly "Focus on Economic Data" lessons.
- What trends do you see in the four data sets?
- What generalizations can you make about the trends of the four data sets?
- Are the real GDP growth and payroll employment trends related?
- Are the real GDP growth and unemployment rate trends related?
- Are the payroll employment and unemployment rate trends related?
- Is the trend of the CPI-U related to the real GDP growth and payroll employment data?
- Is the trend of the CPI-U related to the real GDP growth and payroll employment data?
- If you were a member of the NBER "Business Cycle Dating Committee, would you argue that we are still in a recession?
- Data for real GDP growth, employment and unemployment rate significantly worsened (almost continually) from December 2007 until the second half of 2009. There has been modest improvement since that time.
- As payroll employment decreased, the unemployment rate increased (with few minor) exceptions).
- As GDP growth slowed and turned negative, the unemployment rate increased and payroll employment decreased.
- As payroll employment decreased and real GDP decreased, there was little inflation and, at times, short periods of deflation in consumer prices. (Remember, more volatile energy prices are a significant variable in the CPI data.)]
U.S. State Real and Metropolitan Area GDP Data
Every six months, the BEA releases annual GDP data for the fifty states and for metropolitan areas. The most recent data was released in September, 2011. The current state and metropolitan area GDP release is for the year 2010.
"Real gross domestic product (GDP) increased in 48 states and the District of Columbia in 2010, according to new statistics released today by the U.S. Bureau of Economic Analysis that breakdown GDP by state. Durable–goods manufacturing, retail trade, and finance and insurance were leading contributors to the upturn in U.S. economic growth. U.S. real GDP by state grew 2.6 percent in 2010 after declining 2.5 percent in 2009."
"Real U.S. GDP by metropolitan area increased 2.5 percent in 2010 after declining 2.5 percent in 2009, according to new statistics released today by the U.S. Bureau of Economic Analysis. The economic growth was widespread as real GDP increased in 304 of 366 (83 percent) metropolitan areas, led by national growth in durable-goods manufacturing, trade, and financial activities."
GDP and Per Capita GDP by Region, 2010
Figure 5, below, lists the gross domestic product of the eight U.S. regions and their regional per capita GDP. Note the significant differences between the regions.
Figure 6, below, illustrates the real GDP growth rates of the 50 states and the 8 regions in 2010. Note the areas of relatively high (blue) and relatively low (beige) growth rates.
[Teacher Note: Students can compare their state or region to other states and regions. What factors may have influenced the pace or growth in their state or region? What industries are growing or declining in their state or region?]
NOTE: Unless otherwise cited, all quoted materials in this lesson are from the BEA, National Income and Product Accounts, Gross Domestic Product, 3rd quarter 2011 (third estimate) news release. December 22, 2011.
“"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 1.8 percent in the third quarter of 2011 (that is, from the second quarter to the third quarter), according to the "third" estimate released by the Bureau of Economic Analysis. In the second quarter, real GDP increased 1.3 percent."
U.S. economic growth was slower than desired in Q3 2011, but it is still positive growth. The ongoing debate is over whether or not the government should take further stimulatory actions or let the economy recover on its own? Ask the almost 14 million workers who continue to be unemployed.
Watch the continuing discussion about how the most recent stimulus funds should be spent.
Short Answer Essay Question:
1. If gross domestic product increases by 10 percent over a year, are we better off? Why or why not?
[Possible Answer: Perhaps we are better off. Maybe not. The answer depends upon what is happening to prices and what is happening to population. If prices and population together are rising by more than 10 percent per year, than we, on average, are worse off. We have fewer goods and services per person. If the nation's real per capita GDP increases, we may be "better off."]
The U.S. Central Intelligence Agency (CIA) “World Factbook” ranks the world's 228 nations by various economic measures, including gross domestic product. The largest of the national economies in the current edition are listed below, in Figure 7. All data in this figure are for 2010.
NOTE: The CIA GDP data is reported using “purchasing power parity” a process that determines the relative values of two currencies. It equates the purchasing power of various nations’ currencies and lists them as equivalent to U.S. dollars.
In terms of total size of GDP, the U.S. ranks second, just behind the European Union nations’ total. In terms of real GDP growth rate, the U.S. ranks 127th among the worlds nations. See Figure 8, below.
U.S. Central Intelligence Agency, World Factbook “Guide to Country Comparisons”
In the ranking for GDP per capita, the U.S. ranks 11th among the 228 nations. See Figure 9, below. The country rankings may be a bit deceiving, due to great differences in income distribution, price levels, qualitative differences, data collection methodology, etc.

Take a look at the economic data for the world’s nations available from the CIA World Factbook . What does the data tell you about the various nations?
Choose one nation. Summarize what you perceive is that nation’s “standard of living,” according to its per capita GDP and other measures of social welfare.
[Teacher Note: Here's a chance to have some fun. Have your students throw a dart at a world map or pick country names out of a hat to select countries to research. You may want to leave the industrialized countries off the list and have students research only developing countries - or vice-versa.]
Other ranking of the world's national economies may differ from those estimated by the CIA World Factbook. For instance, the World Bank estimates the U.S GDP in 2010 as $13,336,200,000,000. (http://data.worldbank.org/indicator/NY.GDP.MKTP.CD?order=wbapi_data_value_2010+wbapi_data_value+wbapi_data_value-last&sort=desc) The CIA's 2010 estimate of U.S. GDP is $14,660,000,000,000.
