From 1920 until 1930 Johnson City
again doubled in population from the previous decade. The location of
huge rayon manufacturing plants in neighboring Elizabethton along with
consistent growth in the city's hardwood industries fueled residential
and commercial development. The 1920s were a lively time as the city earned the nickname "Little Chicago." However, just ahead were The Great
Depression and World War II which slowed growth throughout
the Appalachian region and were major factors in Johnson City's limited
population gains from 1930 - 1950. As passenger rail services declined,
the city's role as a regional rail hub also gradually decreased in significance.
