.5 generation
n.— «Sociologists call Mr. Singh and his cohort the “.5 generation,” distinct from the “1.5 generation”—younger transplants who became bicultural through school and work. Immigrant elders leave a familiar home, some without electricity or running water, for a multigenerational home in communities like Fremont that demographers call ethnoburbs.» —“Invisible Immigrants, Old and Left With ’Nobody to Talk To'” by Patricia Leigh Brown New York Times Aug. 31, 2009.
