“…The percent of housing built before 1940, a general control for housing quality, has an alternating sign pattern, so yields no meaningful interpretation. But the percent of workers who commute 45 minutes or more to get to their job has a consistent negative influence on the probability of naturalization, indicating that commuting, a major—and often stressful (see, e.g., Frumkin, Frank, and Jackson, 2004; Ewing et al, 2011)—time sink, acts as an impediment 35 . The locational characteristics category reveals that individuals living farther from CBSA centers—in more suburban, exurban, and/or rural locations—have a higher probability of naturalizing but, at the same time, that density (the inverse of distance from the nearest census tract) increases the probability of naturalization, perhaps by enhancing network effects.…”
