Paul Groth states that some downtown "residents literally cannot exist without them as they have "[few, if any, housing alternatives." There are "myths about today's hotel residents", claiming that they are all "isolated, needy, and disabled; all elderly; all on welfare; all elderly men; or all welfare mothers with three young children...[, socially marginal, all mildly psychotic, all alcoholics or drug addicts, all drifters and transients", with some journalists using the derogatory term "welfare hotel". A 1985 study in Chicago revealed "a large minority of impoverished workers." In New York City, about one third of SRO dwellers are black and one quarter are Hispanic. Most SRO residents do not move more often than apartment renters, contrary to media references to "transients."
