“Ragged urchins play on marquetry floors”: The discourse of filtering is reconstructed, 1920s–1950s

The idea of filtering has played a key role in our understanding of housing markets and in framing federal policy. The origins of the idea, however, and of the term itself, are poorly understood. Drawing loosely on the approach of discourse analysis, this article clarifies both issues, arguing that language shapes how we think about housing policy, and indeed policy itself. The concept of filtering emerged in Great Britain in the late nineteenth century where, by 1900, it informed arguments in favor of municipal (public) housing. It became influential in the United States in the 1920s but in 1938 was still referred to in different ways, notably as “hand-me-down housing.” Here, it was understood more narrowly, as an alternative to public housing. After 1939, the Federal Housing Administration, though not its leading consultant Homer Hoyt, popularized the term “filtering.” The neutral connotations of this metaphorical term suited the agency's goal of developing an apparently objective discourse of housing markets and market analysis. The term was normalized by the early 1960s.
