When the Trump administration unveiled its 2020 budget proposal this week, attention quickly focused on its strong assumptions about future economic growth. The budget assumes 3 percent average GDP growth across the next decade, with 2019 hitting 3.2 percent, a bit stronger than 2018’s 3.1 percent. From there, the number tapers back down to 3.1 percent in 2020, and finally locks in at 2.8 percent by 2026.

These numbers ride higher than those of most private forecasters, as well as those of the Congressional Budget Office, which assumes growth will average close to or less than 2.0 percent.
