Based on the national average household size of 2.61 persons, the estimated number of housing units in Trainsong for 2022 is 498. This number of housing units, combined with the moderate population density, suggests a neighborhood that maintains a suburban feel while being close to urban amenities.

Trainsong's proximity to railroad tracks likely influences the neighborhood's character and demographic makeup. The presence of railways might attract residents who work in transportation or related industries, or those who appreciate the historical significance of rail in the area's development.

The population fluctuations could indicate various factors, such as changes in local employment opportunities, housing market shifts, or evolving preferences for urban versus suburban living. The recent decline from the 2016 peak might suggest that some residents have moved to other areas of Eugene or beyond, possibly seeking different amenities or housing options.

Despite these changes, the consistent moderate density over the years indicates that Trainsong maintains a stable suburban character. Residents likely have access to local parks, schools, and basic shopping amenities to serve its population of just over 1,300 people.

Trainsong presents a dynamic light suburban neighborhood that has experienced both growth and contraction over the past decade. Its current population and density suggest a community that offers a blend of suburban living with urban accessibility, shaped by its railway heritage and evolving in response to broader urban development trends in Eugene.
