There are approximately 50,000-70,000 men, women, and children who are homeless in NYC right now. On average, 30% of homeless have a mental illness.

So there are approximately 60k * 0.30 = 18,000 homeless people in NYC with a mental illness.

The mental health problem in NYC is a reflection of our federal and state government's ability to properly provide basic care for the small minority of the population who need support. We need to find a way to motivate people to take their lives more seriously and provide support to those who cannot function.
