Homeless Population in the Summer
If you drive through a neighborhood and see 20 homeless people in as many minutes, that's a clear warning sign. However, if you live in a climate with a formidable winter, you may only get a true sense of the homeless population in the summer. Also, if you are looking in a busy city, you may not be able to find an area completely free of the homeless; if you are unwilling to move farther into the suburbs, this may be a tradeoff you can live with.
