The median income in Newville has shown an overall upward trend, increasing from $54,580 in 2013 to $61,873 in 2022, a rise of approximately 13.4% over the decade. This growth has not been consistently linear, with year-to-year fluctuations observed.

The population has experienced a slight decline during the same period, decreasing from 12,249 in 2013 to 11,577 in 2022, a reduction of about 5.5%. The combination of rising median income and declining population may indicate economic improvement for remaining residents, possibly due to outmigration of lower-income households or economic growth benefiting those who stayed.

Newville's demographic stability contrasts with national trends towards increasing diversity in many areas of the United States. While many urban and suburban areas have experienced significant increases in racial and ethnic diversity over the past decade, this zip code has maintained its predominantly white composition.

The economic trends in Newville generally align with broader national patterns of income growth over the past decade. However, the population decline observed here differs from the growth experienced in many suburban and exurban areas, particularly following the COVID-19 pandemic when many people moved out of urban centers.

Newville demonstrates demographic stability amid moderate economic growth. Its persistent Low Diversity and White Majority status, combined with rising incomes and a slightly shrinking population, indicate a community that has experienced limited demographic change but some economic improvement over the past decade. This pattern may suggest a community that is somewhat insulated from broader demographic shifts occurring in more urban or rapidly growing areas of the country.
