The median income has shown an upward trend, rising from $58,664 in 2013 to $71,318 in 2022, an increase of about 21.6% over nine years. This income growth coincides with the period of slight diversification (2013-2018) and continues through the return to lower diversity (2018-2022). The population has remained relatively stable, fluctuating between about 4,800 and 5,500 residents.

The persistent white majority in this zip code contrasts with national trends towards increasing diversity in many suburban and urban areas. The income growth in this area aligns with broader economic recovery trends post-2008 recession, but the stability of the racial makeup suggests that this growth hasn't led to significant demographic changes as seen in some other communities.

The brief period of increased diversity (2013-2018) followed by a reversal could indicate a temporary influx of diverse populations that didn't establish long-term residency, or economic or social factors that may have discouraged retention of minority populations. The stable population and increasing median income suggest that this community may be experiencing some level of gentrification or becoming more attractive to higher-income white residents.

In conclusion, while this zip code has experienced some economic growth over the past decade, it has largely resisted demographic shifts seen in many other parts of the country. The community remains characterized by low diversity and a strong white majority, with only minor fluctuations in its racial composition. The economic improvements have not translated into sustained increases in diversity, suggesting that local factors or community dynamics may be playing a role in maintaining the current demographic status quo.
