In 1950, the area between 31st Street and Armour Boulevard on Troost Avenue was a dense community of almost exclusively white residents. This changed drastically over the next fifty years. The population density greatly decreased as many Kansas City residents relocated outside the city center and the population became decentralized. These changes also led to differences in race and class. As many wealthy, white residents expanded outward, this area of Troost Avenue was left to predominately low-income, minority residents. By the 2000s, Troost Avenue had become a dividing line. Residents on the west side had a more even distribution of race and a higher median income. Residents on the east side were predominately minorities with a lower median income.
