The growth of urban population of Curitiba, that turned the city in a modern metropolis, has generated some social problems. Like other major Brazilian cities, Curitiba has seen the emergence of slums in some neighborhoods and around the city, and the growth of street inhabitants, that many times had been sent of other cities and States, and are dropped in the streets of the city. This fact has made a small growth of crime level, but is not comparable to other major Brazilian cities.
