How common is schizophrenia?

Schizophrenia is a serious mental disorder that often develops in adolescence or early adulthood and affects approximately 24 million people worldwide. Approximately 1 in 100 people around the world has schizophrenia. In many studies it has been found that more males than females are diagnosed with schizophrenia, and high rates of schizophrenia among migrants have been described in various settings.

Schizophrenia affects about 1% of the population worldwide. In the United States, 1.1% of the adult population has this diagnosis. When you look at it from the perspective of a percentage, 1% seems quite small. However, 1% of the U.S. population means that about 3 million men and women over the age of 18 have schizophrenia.

Schizophrenia affects about 1 out of every 100 people around the world. It usually rears its ugly head in people between the ages of 16 and 30. It is as common in men as it is in women, but men seem to get sick at younger ages than women. However, if you make it to the top of the hill (age 45), it is extremely unlikely that you will be diagnosed unless there are prior signs or symptoms.

Schizophrenia is a relatively common disorder, affecting about one out of 100 people. In fact, 1/5 of those receiving social security disability benefits are people with schizophrenia, and the disorder ranks ninth on the causes of disability throughout the world. Surprisingly, the disorder is more common than some diseases people hear more about, such as multiple sclerosis and Alzheimer's disease.
