The median income in this zip code has fluctuated over the past decade. It reached its peak at $53,096 in 2015 and its lowest point at $43,254 in 2019. The 2022 data shows a median income of $47,972, indicating a recovery from the 2019 low but still below the 2015 peak.

The strengthening of the Black majority coincided with periods of both income growth and decline. The initial increase in Black population percentage from 2013 to 2016 occurred alongside a slight increase in median income. However, the continued increase from 2016 to 2019 corresponded with a decline in median income.

The population has remained relatively stable over the decade, with minor fluctuations. The most recent trend shows a slight decrease from 18,038 in 2021 to 17,425 in 2022, which could potentially impact local economic dynamics.

The trends observed in this zip code reflect some broader patterns seen in many urban areas across the United States. The increasing concentration of Black residents, coupled with a decline in the White population, is consistent with patterns of demographic change observed in many inner-city areas.

The income fluctuations, particularly the dip in 2019 and subsequent recovery, may reflect broader economic trends. The emergence of small but growing Hispanic, Asian, and multiracial populations aligns with national trends of increasing diversity in many urban and suburban areas.

In conclusion, while zip code 36618 in Mobile, Alabama, remains a "Black Majority" community, it shows signs of subtle demographic shifts and economic fluctuations. The area's ability to maintain a stable population while experiencing these changes suggests a degree of community resilience in the face of demographic and economic shifts.
