The REAL PROPERTY INVENTORY OF METROPOLITAN CLEVELAND (RPI), collected detailed statistics and issued reports about population trends, housing, manufacturing, retail business, and other aspects of life in the Cleveland area. RPI was initiated by the Cleveland Real Estate Board, which organized the Committee on Real Property Inventory and then chose local statistician
RPI's publications included "A Sheet-a-Week," a 2-page publication begun in 1933 that gave different statistical reports each week; annual reports (which by the mid-1950s included Family & Housing Characteristics and Retail Stores & Shopping Centers); and special reports, such as those on standard of living (1935), and manufacturing (1951). In its heyday, between 1933 and 1959, RPI was an important source of information to local business, government, and social planners trying to meet local needs. The Real Property Inventory continued to publish the RPI "Bulletin" as late as 1978. In Sept. 1979 RPI merged with the Northern Ohio Urban System Research Corp. and reorganized as the Northern Ohio Research Information Center, a group serving Cuyahoga, Lorain, Medina, Summit, Portage, Geauga, Lake, and Ashtabula counties. The group continued publishing data until the early 1980s.
