How Many People Have OCD?

OCD affects men, women and children of all races and backgrounds equally.


Our best estimates are that about 1 in 100 adults – or between 2 to 3 million adults in the United States – currently have OCD.1,2   
This is roughly the same number of people living in the city of Houston, Texas.



There are also at least 1 in 200 – or 500,000 – kids and teens that have OCD.  This is about the same number of kids who have diabetes.  

That means four or five kids with OCD are likely to be enrolled in any average size elementary school.  In a medium to large high school, there could be 20 students struggling with the challenges caused by OCD.3
