In the United States, the prevalence of PE varies by age. At age 4 years, 25% of children frequently wet the bed, but by age 7 years, only 5-10% still wet the bed, and by age 10 years, fewer than 5% of children do so.

The resolution rate of PE is approximately 15% per year; by the late teenaged years, very few patients have the condition. The resolution rate is often used as a justification for waiting and not treating PE. However, it probably is not applicable to children who wet every night and likely applies only to those children who have already started to have dry nights.

Worldwide, the prevalence of PE seems to be approximately the same, though no standardized evaluation of the prevalence of bedwetting has been made on a global basis.
