The census gives his job as a labourer for the WPA, a few neighbors were miners though.
Works Progress Administration - Wikipedia, the free encyclopedia
''The Works Progress Administration (renamed in 1939 as the Work Projects Administration; WPA) was the largest and most ambitious New Deal agency, employing millions of unemployed people (mostly unskilled men) to carry out public works projects,[1] including the construction of public buildings and roads. In much smaller but more famous projects the WPA employed musicians, artists, writers, actors and directors in large arts, drama, media, and literacy projects.[1]
Almost every community in the United States had a new park, bridge or school constructed by the agency. The WPA's initial appropriation in 1935 was for $4.9 billion (about 6.7 percent of the 1935 GDP), and in total it spent $13.4 billion.[2]''
Edited to add, the families on the street could also have been Slovakian, the names lead me to think so.
