In January 1924 he devised his Neighborhood Unit theory defining a neighborhood as the area served by an elementary school and bounded by arterial roads; this theory was published in study number 7 of the Regional Plan of New York and Its Environs.  Perry also wrote REBUILDING OF BLIGHTED AREAS (1933); PLANNING IMPROVEMENT OF YOUR OWN NEIGHBORHOOD (1935); and HOUSING FOR THE MACHINE AGE (1939).
