To understand this, we can ask how long it would take for those with incomes at the poorest 10% cutoff to achieve the current incomes of the richest 10% cutoff (which is 14,500 international-$). The difference between the level of real GDP and potential GDP is known as the output gap. Policymakers watch the GDP gap closely and make adjustments to try and keep growth in line with the long-term trend.

In addition, early income estimates of quarterly corporate profits, bonuses, stock options, and other incomes may reflect income earned over the course of the year, but recorded only in the quarter when it is paid.
