In the same year, Congress passed the Voting Rights Act. The proportion of hospital-based SCLC cases in counties was higher than that in cities from 2008 to 2017.

In this year, King had attempted to register 400 black voters in the city. The proportion of hospital-based SCLC cases was notably different from that of population-based SCLC cases. In these papers, he asked whether an organization was needed to coordinate these activities. Following the success of the boycott in 1956, Bayard Rustin wrote a series of working papers to address the possibility of expanding the efforts in Montgomery to other cities throughout the South.
