United States GDP by Sector

Current Sector Composition of US GDP

In 2021, the services sector accounted for 77.60% of US value-added, making it the dominant component of the economy. Industry contributed 17.88%, while agriculture represented just 0.96%. These shares reflect a long-term structural shift toward services, which has been underway for decades. The three sectors collectively sum to 96.44% of GDP, with the remainder comprising minor adjustments such as taxes and subsidies.

The employment shares for 2025 show a similar pattern, with services employing 79.56% of the workforce, compared to 18.91% in industry and 1.52% in agriculture. Services' employment share is slightly higher than its value-added share, indicating a lower average labour productivity relative to industry. Industry's employment share of 18.91% exceeds its value-added share of 17.88%, suggesting a modest productivity gap. Agriculture's employment share of 1.52% is larger than its 0.96% value-added share, consistent with its labour-intensive nature.

Long-Term Trends in Sector Shares

Agriculture's value-added share declined from a mean of 1.23% in the 1990s to 0.95% in the 2020s, a drop of 22.8% across the three decades. The steepest decade decline occurred in the 2000s, when the share fell 16.5% from 1.15% in 2000 to 0.96% in 2009. By 2021, agriculture's share had stabilised at 0.96%, though it remained below the 2010s mean of 1.05%.

Industry's value-added share contracted from a mean of 22.79% in the 1990s to 17.70% in the 2020s, a cumulative decline of 22.3%. The largest drop occurred in the 2000s, when the share fell 14.2% from 22.45% in 2000 to 19.27% in 2009. In the 2010s, the decline moderated to 5.3%, and by 2021 the share stood at 17.88%, slightly above the 2020s mean of 17.70%.

Services' value-added share rose from a mean of 72.31% in the 1990s to 77.87% in the 2020s, an increase of 7.7%. The 2000s saw the strongest growth, with the share rising 5.1% from 72.82% in 2000 to 76.51% in 2009. Growth slowed to 1.2% in the 2010s, and by 2021 the share was 77.60%, slightly below the 2020s mean of 77.87%.

Employment Trends by Sector

Agricultural employment fell from a mean of 2.82% in the 1990s to 1.62% in the 2020s, a decline of 42.6%. The 2000s saw the steepest drop, with employment falling 27.7% from 2.40% in 2000 to 1.73% in 2009. By 2025, agricultural employment was 1.52%, the lowest recorded in the dataset.

Industry employment declined from a mean of 23.40% in the 1990s to 19.20% in the 2020s, a fall of 17.9%. The 2000s experienced the largest contraction, with employment dropping 12.3% from 22.67% in 2000 to 19.89% in 2009. In the 2010s, employment stabilised, growing 1.4% to 19.75% by 2019, but by 2025 it had fallen to 18.91%.

Services employment increased from a mean of 73.78% in the 1990s to 78.51% in the 2010s, before rising further to 79.56% in 2025. The 2000s saw the fastest growth, with employment rising 4.6% from 74.93% in 2000 to 78.38% in 2009. By 2025, services employed 79.56% of the workforce, the highest share on record.

Structural Transformation Since 1980

The United States economy has undergone a profound structural transformation since 1980, characterised by a sustained contraction in agriculture and industry and a corresponding expansion of services. Agriculture's share of GDP fell from a mean of 1.23% in the 1990s to 1.05% in the 2010s, while industry declined from an average of 22.79% to 18.84% over the same period. Services, conversely, rose from a mean of 72.31% in the 1990s to 76.51% in the 2010s. This shift reflects the long-term deindustrialisation of the US economy and the growing dominance of service-sector activities.

The agricultural sector experienced its steepest relative decline during the 2000s, with value added falling by 16.5% from 1.15% of GDP in 2000 to 0.96% in 2009. This contraction continued into the 2010s, where the sector's share dropped a further 18.5% from 1.03% in 2010 to 0.84% in 2019. By 2021, agriculture contributed just 0.96% of GDP, down from 1.34% in 1997. Employment in agriculture followed a similar trajectory, falling from 2.94% of total employment in 1991 to 1.52% in 2025, a decline of 48.1% over 34 years.

Industry's share of GDP contracted most sharply in the 2000s, declining by 14.2% from 22.45% in 2000 to 19.27% in 2009. The 2010s saw a further reduction of 5.3%, from 19.31% in 2010 to 18.28% in 2019. By 2021, industry accounted for 17.88% of GDP, compared to 23.13% in 1997. Industrial employment also shrank, dropping from 24.37% of total employment in 1991 to 18.91% in 2025, a loss of 5.5 percentage points. The 2000s were the most severe decade for industrial job losses, with employment falling 12.3% from 22.67% to 19.89%.

Services expanded steadily to become the dominant sector, with its GDP share rising from 71.81% in 1997 to 77.60% in 2021. The fastest growth occurred in the 2000s, when the services share increased by 5.1% from 72.82% in 2000 to 76.51% in 2009. The 2010s saw a more modest rise of 1.2%, from 76.28% in 2010 to 77.18% in 2019. Services employment also grew, from 72.69% of total employment in 1991 to 79.56% in 2025, an increase of 6.9 percentage points. The 2000s saw the largest employment gain, with services' share rising 4.6% from 74.93% to 78.38%.

The 2020s have introduced some deviations from the long-term trend. Agriculture's GDP share increased by 1.1% between 2020 and 2021, from 0.95% to 0.96%, while industry grew by 2.1% from 17.51% to 17.88%. Services, however, contracted by 0.7% from 78.14% to 77.60% over the same period. These movements likely reflect pandemic-related disruptions and the subsequent recovery in goods-producing sectors. Despite these short-term fluctuations, the structural shift towards services remains the defining feature of the US economy since 1980.

Employment vs Value-Added: Productivity Gaps

In 2021, agriculture contributed 0.96% of US value-added but employed 1.52% of the workforce in 2025, indicating a below-average productivity relative to its output share. The sector's value-added share declined from 1.15% in 2000 to 0.96% in 2021, a fall of 16.5% over the 2000s. Employment in agriculture dropped from 2.40% in 2000 to 1.52% in 2025, a steeper decline of 36.7% over the same period, suggesting that labour has exited faster than output has contracted.

Industry demonstrates a pronounced productivity advantage, contributing 17.88% of value-added in 2021 but employing only 18.91% of workers in 2025. The sector's value-added share fell from 23.13% in 1997 to 17.88% in 2021, a decline of 22.7% over 24 years. Employment in industry dropped from 24.37% in 1991 to 18.91% in 2025, a fall of 22.4%, meaning output and labour shares have declined at similar rates, preserving a relatively high output-per-worker ratio.

Services accounted for 77.60% of value-added in 2021 while employing 79.56% of workers in 2025, reflecting a slight productivity deficit relative to the overall economy. The services value-added share rose from 71.81% in 1997 to 77.60% in 2021, an increase of 8.1%. Employment in services grew from 72.69% in 1991 to 79.56% in 2025, a rise of 9.4%, indicating that labour absorption has marginally outpaced output growth in the sector.

The productivity gap between industry and services is stark when comparing output per worker. In 2021, industry generated 17.88% of value-added with 18.91% of employment in 2025, implying a relative productivity ratio of 0.95. Services produced 77.60% of output with 79.56% of employment, yielding a ratio of 0.98. Agriculture had a ratio of 0.63 (0.96% output versus 1.52% employment), highlighting its lower productivity relative to the other sectors.

Over the 2010s, industry value-added declined by 5.3% from 19.31% in 2010 to 18.28% in 2019, while industry employment rose by 1.4% from 19.49% in 2010 to 19.75% in 2019. This divergence suggests a slight erosion of industry's productivity advantage during the decade. In contrast, services value-added grew by 1.2% from 76.28% to 77.18% over the same period, while services employment fell by 0.3% from 78.66% to 78.46%, indicating a modest productivity improvement.

The 2020s have seen a reversal in industry's productivity trend. Industry value-added rose by 2.1% from 17.51% in 2020 to 17.88% in 2021, while industry employment fell by 2.6% from 19.42% in 2020 to 18.91% in 2025. This combination of rising output share and falling labour share has widened the productivity gap in favour of industry. Services value-added fell by 0.7% from 78.14% in 2020 to 77.60% in 2021, while services employment rose by 0.9% from 78.84% in 2020 to 79.56% in 2025, narrowing the sector's relative productivity.

Agriculture's productivity gap has persisted across decades. The sector's value-added share averaged 1.05% in the 2010s, while its employment share averaged 1.83% over the same period. By 2021, agriculture's output share stood at 0.96% versus employment of 1.52% in 2025, a ratio of 0.63. This persistent gap reflects structural factors such as smaller farm sizes and lower capital intensity relative to industry, reinforcing the sector's position as the least productive in the US economy.

Trade, Specialisation, and Growth Implications

The United States economy is dominated by services, which contributed 77.6% of value added in 2021, while industry accounted for 17.9% and agriculture for 0.96%. This sectoral structure shapes the country's export composition, with services such as financial services, software, and intellectual property generating a substantial trade surplus. In contrast, the United States runs a persistent deficit in manufactured goods, reflecting a specialisation in high-value, knowledge-intensive services. The reliance on services for over three-quarters of output underpins a trade profile that is less exposed to global commodity price cycles but sensitive to cross-border regulatory and licensing frictions.

High-tech exports, including aerospace, pharmaceuticals, and information technology hardware, form a critical component of the industrial sector's contribution to trade. Industry value added fell from 23.1% in 1997 to 17.9% in 2021, a decline of 5.2 percentage points over 24 years. Despite this relative shrinkage, the United States remains a leading exporter of advanced manufactured goods, supported by strong research and development spending. The high-tech share of manufactured exports has remained elevated, reflecting a specialisation in products with high value added per unit. This focus provides a buffer against low-cost competition in basic manufacturing but ties export performance to sustained innovation capacity and protection of intellectual property.

The sectoral structure implies specific growth dynamics. Services employment rose from 72.7% in 1991 to 79.6% in 2025, while industry employment fell from 24.4% to 18.9% over the same period. This shift towards services has been associated with lower productivity growth compared to manufacturing, a pattern observed across advanced economies. The United States has offset this through high productivity in information and financial services, which have driven overall GDP per hour worked. However, the declining share of industry, which typically exhibits faster productivity gains, poses a structural headwind to long-run growth unless services productivity accelerates.

Economic resilience is influenced by the diversification inherent in a services-dominated economy. Services value added grew from 71.8% in 1997 to 77.6% in 2021, providing a broad base that reduces vulnerability to sector-specific shocks. During the 2008 financial crisis, services value added rose from 76.3% in 2009 to 77.2% in 2010, while industry value added fell from 19.3% to 18.0% in the same period. This counter-cyclical behaviour of services employment—which increased from 78.4% in 2009 to 78.7% in 2010—helped stabilise the labour market. The large services sector also supports resilience through domestic demand, as many services are non-tradable and less exposed to global trade disruptions.

Specialisation in high-value services and advanced manufacturing carries risks. The agriculture sector, though small at 0.96% of value added in 2021, is a net exporter and faces tariff volatility. Industry employment declined by 2.6% between 2020 and 2025, from 19.4% to 18.9%, indicating ongoing structural adjustment. Services employment fell by 0.3% between 2019 and 2025, from 78.5% to 79.6%, but this masks compositional shifts towards lower-productivity subsectors. The United States must navigate these trends by investing in digital infrastructure and workforce training to sustain its comparative advantage in high-tech exports. Failure to do so could erode the export premium that currently supports the trade balance and overall economic growth.
