Incomes Over $100,000 by ZIP Code

August 29, 2018 Data Viz

By Julia Vieira, Research Intern, and Phil Sletten, Policy Analyst

In 2015, New Hampshire residents filed almost 685,000 federal tax returns. Roughly 20.6 percent of tax returns in the state reported incomes of $100,000 or more. These tax returns may have included individuals, joint filers, and families with and without dependents, and this analysis does not control for income collected on a per capita basis. However, differences between ZIP Codes indicate a significant geographic disparity in filers reporting high incomes within the state. In eight ZIP Codes, more than 40 percent of total tax filers reported income of $100,000 or more, and one of those had over 50 percent of filers reporting such incomes, whereas in other ZIP Codes no tax filers reported such income levels.

Using publicly-available data from the United States Internal Revenue Service on aggregated 2015 tax returns, the map below shows the percent of tax filers with $100,000 or more in reportable income across the state’s ZIP Codes. In the map, darker green represents ZIP Codes with greater shares of tax filers with $100,000 or more in reportable income.

The southeastern part of the state has the largest shares of tax filers with $100,000 or more in reportable income, whereas the northern part has the lowest shares. This measure showing distributions of higher-income individuals suggests more opportunities to earn higher incomes exist in the southeastern part of the state than in other regions. Opportunities for higher incomes may attract people to certain regions, and fewer opportunities for higher incomes may conversely make other regions less attractive for mobile populations, creating the risk of a downward cycle for lower-income areas.

The share of high-income tax filers by municipality, particularly shared with other measures of income, can be an indication of municipal fiscal capacity. Higher resident incomes in municipalities allows local governments to increase revenue to improve service provision and investment. However, if municipalities have a disproportionately larger number of residents with lower incomes, local governments may face more constraints relative to raising funds, diminishing the quality of services they provide and their ability to make necessary investments.

New Data Show Food Insecurity Levels Declining Prior to the COVID-19 Crisis

10 Sep 2020

According to data released on September 9 by the United States Department of Agriculture, food insecurity levels in New Hampshire continued to decline during 2019, prior to the onset of the ongoing COVID-19 crisis. The report outlines the trends of reduced food insecurity in the nation and in New Hampshire, declining from the higher levels resulting from the Great Recession of 2007 to 2009. The overall improvements to the state economy through 2019, along with the effectiveness of key nutritional aid programs, did contribute to lower levels of food insecurity, although the benefits of the economic recovery did not reach all Granite Staters in an equal or timely manner. Although food insecurity levels declined through the years preceding 2020, the current crisis facing Granite Staters is not reflected in these 2019 data. The recent economic pressures on many individuals and families with lower incomes in New Hampshire have been severe, and current levels of food insecurity are very likely to be substantially higher.
