Economic changes were notable despite the stable demographics. The median income increased from $37,588 in 2013 to $59,655 in 2022, representing a 59% growth. This suggests an improving economic situation for the residents.

The population remained relatively stable, decreasing slightly from 1,788 in 2013 to 1,779 in 2022, a change of less than 1%. The combination of stable population and increased median income may indicate economic growth among existing residents rather than an influx of higher-income newcomers.

The 59% increase in median income over a decade is substantial and likely exceeds national averages for income growth. However, the lack of racial diversity in this area contrasts with national trends of increasing diversity in many parts of the United States.

The zip code's consistent "Low Diversity" categorization throughout the decade suggests it has not experienced demographic shifts seen elsewhere. This could be due to factors such as geographic isolation, limited economic opportunities for newcomers, or strong community ties maintaining the existing population.

Zip code 16639 in Blandburg, Pennsylvania, has maintained its status as a "Low Diversity" community over the past decade while experiencing significant economic growth as evidenced by the substantial increase in median income. This combination of demographic stability and economic improvement presents a case study in community development and the relationship between racial composition and economic progress in small, homogeneous communities.
