Maywood has maintained its status as a White Majority community over the past decade, transitioning from Low Diversity in the early 2010s to Moderate Diversity by 2022. This change is primarily attributed to an increase in the Hispanic population from 17% in 2013 to 20% in 2022, and fluctuations in the Black population, which reached 13% in 2017 before settling at 10% in 2022. The community exhibits characteristics of a Transitional Community, with consistent growth in the Hispanic population and an increase in residents identifying as two or more races from 2% in 2015 to 4% in 2022.

The demographic shifts in Maywood have occurred alongside economic fluctuations. The median income has varied, ranging from $37,430 in 2015 to $43,021 in 2021, before decreasing to $39,027 in 2022. This economic instability may have both influenced and been influenced by the changing demographic composition. The gradual population decrease could be attributed to factors such as economic opportunities elsewhere or changing housing preferences. As some residents, possibly predominantly white, have left, they have been partially replaced by a more diverse group of newcomers.
