The median income in Castlemont has fluctuated over the years, showing a general upward trend despite some volatility. In 2013, the median income was $40,183, rising to a peak of $49,274 in 2017, coinciding with the shift to a Hispanic Majority. Recent years have seen some decline, with the 2022 median income at $43,620. This economic pattern correlates with demographic changes. The period of highest income (2016-2017) aligned with the strongest Hispanic representation. The recent diversification trend has coincided with a slight decrease in median income.

Population figures have remained relatively stable, fluctuating between about 3,100 and 3,900 residents over the decade. This stability in population size, despite significant demographic shifts, suggests that changes are primarily due to internal community dynamics rather than large-scale migration patterns.

Castlemont's demographic evolution mirrors broader trends seen in many urban areas across the United States, particularly the increasing Hispanic population and the growth in multiracial identities. The neighborhood's specific pattern of transitioning from a Black Plurality to a more diverse mix reflects Oakland's complex racial history and ongoing socio-economic changes.

The economic fluctuations in Castlemont suggest a community that is economically vulnerable to demographic shifts. The median income, while showing some improvement over the decade, remains significantly below the California state median (which was around $78,672 in 2021), indicating persistent economic challenges in the neighborhood.

Castlemont exemplifies a Transitional Community, moving from distinct racial pluralities towards Higher Diversity. This transition brings both opportunities and challenges, as reflected in the fluctuating economic indicators. The neighborhood's evolution underscores the complex interplay between demographic changes and economic outcomes in urban American communities.
