The median income in this zip code has shown considerable volatility. It peaked at $192,554 in 2019 but has since declined to $134,500 in 2022. This volatility may be related to the small population size, where individual household changes can significantly impact overall statistics. The population has fluctuated between 9 and 33 residents over the decade, with no clear long-term growth or decline trend. This instability in population could be influencing both demographic and economic metrics.

Periods of higher diversity (2020-2021) coincided with lower median incomes compared to years with a stronger white majority. However, given the small population, this correlation should be interpreted cautiously.

With such a small population, this zip code's demographic and economic trends may not be representative of broader Brooklyn or New York City patterns. The changes observed could be heavily influenced by the decisions of just a few households. The high median incomes, despite recent declines, suggest this area may be part of broader gentrification trends seen in many parts of Brooklyn over the past decade.

The fluctuation between moderate and high diversity, with a persistent white majority, reflects the complex demographic changes occurring in many urban areas across the United States. Zip code 11251 presents a unique case study of a small, affluent community within Brooklyn experiencing demographic transitions. While maintaining a white majority, it has shown trends towards increased diversity, albeit with recent reversals. The economic volatility and small population size make it challenging to draw broader conclusions, but the area's evolution offers insights into the dynamic nature of urban demographics and economics in microcosm.
