Key Facts Household Income Distribution Overall
Northern Virginia is known for having communities with some of the highest incomes in the United States, including the county with the highest median household income in the nation. High incomes coincide with the large, thriving business community of the Northern Virginia region. While high incomes exist, we must recognize that there are segments of the community that are lower income and in need of assistance that live in this prosperous region of the country.
About the Data and Proper Data Interpretation
Median household income data is sourced from the U.S. Census Bureau 2000 Census and the American Community Survey (ACS). It is important to note that any data sourced from the ACS is based on a small sample of the population of a place. Areas with smaller populations, such as the cities of Northern Virginia, may have a larger margin of error in the data due to the survey sample size being small. This is less of an issue the larger the population. The margin of error is shown in the popup that is displayed when hovering over a bar in the bar charts. If there is a large increase or decrease in the estimate from one time period to the next, and the margin of error is large and overlaps other periods, then the large change between time periods is likely due to statistical sampling error and is not considered statistically significant. In addition to the margin of error, the accuracy of the American Community Survey data for an area can be gaged by evaluating the trend. If the data has a clear trend then the data from one period to the next can be deemed reliable.
