The zip code has experienced significant economic growth over the past decade. Median household income has increased from $62,133 in 2013 to $75,802 in 2022, representing a 22% increase. There was a notable increase in median income from $75,179 in 2020 to $83,364 in 2021, followed by a slight decrease in 2022. The population has grown modestly from 8,878 in 2013 to 9,895 in 2022, an 11.5% increase.

The economic growth appears to correlate with the slight increase in the white majority percentage, suggesting that the area may be becoming more attractive to affluent white households. The modest increases in Hispanic and multiracial populations, coupled with the decrease in the Black population, might indicate some level of gentrification or changing neighborhood dynamics.

The median household income in this zip code ($75,802) is higher than the national median. The racial composition of this zip code, with its strong white majority, is less diverse than the national average. As of 2021, the United States was about 59% white, so this zip code's 84% white population is considerably higher. The slow increase in Hispanic and multiracial populations aligns with national trends of increasing diversity, but at a much slower rate than seen in many urban areas across the country.

In conclusion, while the 45209 zip code in Cincinnati remains a "Low Diversity" area with a strong "White Majority," there are subtle signs of slow demographic changes. The area has experienced significant economic growth over the past decade, which may be influencing and being influenced by these demographic shifts. The community appears to be slowly becoming more diverse, but at a rate much slower than national trends, suggesting it remains a relatively insulated, affluent, predominantly white enclave within the broader Cincinnati area.
