As more and more families moved in, the neighborhood increasingly became crowded. A narrative that accompanied the 1984 application of the Fourth Ward to become listed in the National Register of Historic Places, based on various historical documents and deed records, said that the crowded conditions and high rent prices may have led to a riot in 1917 when African-American soldiers stationed in the area attacked White people. By the 1920s and 1930s the population density of Freedmen's Town was almost six times that of the average of the entire City of Houston.
