The United States saw a decrease in single room occupancy housing during the period of 1960s and 1970s urban decay. For example, in Chicago 81% of the SRO housing stock disappeared between 1960 and 1980. Since the early 1970s, the supply of SRO spaces did not meet the demand in US cities. In 1970, newspapers in the US wrote about an "SRO crisis". Downtown SRO hotels offer few and possibly no rooms to rent to tourists. Indeed, since the end of WWII, the inexpensive hotels that became SROs were lost and not replaced, with the losses coming from conversion to office space, demolition, or upgrading to tourist rental. For example, in San Francisco from 1975 and 1980, 6,085 SRO rooms were lost; in Chicago, from 1973 and 1984, more than 23,000 SRO units were lost. Some viewed the removal of SRO hotels as a good thing, as it meant the "removal of substandard housing and unwanted neighbors" and their "public nuisance"; on the other hand, it was also viewed as causing more homelessness.
