In answer to my colleague Roger Hopkins Burke's request today about the earliest known use of the term "social housing". We can now know that the first known published use of the term "social housing" dates back at least as far as 1913.
Once again the Internet Date Detection (IDD) method beats the etymological experts in the Oxford English Dictionary (OED). This time by 15 years on the earliest, to date (5th September 2016), discovered use of the term "social housing".
The OED (5th September 2016) has it: "1928 Ann. Amer. Acad. Polit. & Social Sci. 140 291 Outstanding social housing experiments are the Schmidlapp houses in Cincinnati, [etc.]."
The ID method (see my book Nullius for an easy step by step guide on how to use the method with Google Chrome) gets back as far as 1913: To The Forerunner vol Iv No 12. December 1913: On Google here and verified on Hathi Trust -Here.
