Tillicum, a neighborhood in Lakewood, Washington, is characterized as a White Majority community with a median income of $53,743 as of 2022. The neighborhood experienced significant population growth, increasing from 4,282 residents in 2010 to 7,654 in 2022. Tillicum's proximity to Joint Base Lewis-McChord potentially influences its demographic composition and economic conditions.

Over the past decade, Tillicum has maintained its status as a White Majority community, but with notable changes. Evidence suggests that Tillicum is becoming a Transitional Community. The Hispanic population increased from 20% in 2013 to 25% in 2015, then stabilized around 17-18% in recent years. The "Two or More Races" category grew from 5% in 2013 to 13% in 2020, indicating increasing diversity. By 2022, the neighborhood exhibited characteristics of Moderate Diversity. Whites remained the majority at 56%, with significant representation from Black (9%), Hispanic (18%), and multiracial (7%) groups. Asian and Pacific Islander populations maintained relatively stable representations throughout the decade, consistently around 4-5% and 1-2% respectively.

The median income in Tillicum has shown fluctuations over the years, possibly correlating with demographic shifts. From 2013 to 2019, there was a general upward trend in median income, rising from $47,256 to $61,879. This coincided with the period of increasing diversity. The years 2020-2022 saw significant income fluctuations, with a sharp drop in 2020, a rebound in 2021, and another decrease in 2022. These changes occurred as the racial composition stabilized. The substantial population increase (78% growth from 2010 to 2022) didn't consistently correlate with income growth, suggesting complex socio-economic dynamics at play.
