Real gross domestic product (GDP) is projected to grow by 2.3 percent in 2019 – down from 3.1 percent in 2018 – as the effects of the 2017 tax act on the growth of business investment wane and federal purchases, as projected under current law, decline sharply in the fourth quarter of 2019. Nevertheless, output is projected to grow slightly faster than its maximum sustainable amount this year, continuing to boost the demand for labor and to push down the unemployment rate.
After 2019, annual economic growth is projected to slow further – to an average of 1.7 percent through 2023, which is below CBO’s projection of potential growth for that period. From 2024 to 2029, economic growth and potential growth are projected to average 1.8 percent per year – less than their long-term historical averages, primarily because the labor force is expected to grow more slowly than it has in the past.
