The early years of the twenty-first century have seen a major decline in the volume of migration from Mexico to the United States. According to one study, during the 2005–2010 period, slightly more Mexicans left the United States (1.39 million) than entered it (1.37 million), a change in the pattern of the last several decades.1 Another study finds that fewer Mexicans than non-Mexicans were apprehended at U.S. borders in 2014, a historic first.2

Hit hard by the national decline in natural-resource and manufacturing jobs, North Country communities in northern New Hampshire and bordering areas of Maine and Vermont (Figure 1) continue to face challenges in restructuring their economies.1 A 2008 study classified Coös County, New Hampshire, and Oxford County, Maine, as “amenity/decline” regions, a common pattern in rural America where historically resource-dependent places experience decline in their traditional industries, even while natural amenities present new opportunities for growth in areas such as tourism or amenity-based in-migration. Complicating this transition, there is often out-migration of young adults seeking jobs and financial stability elsewhere, as new industries in rural areas tend toward seasonal employment or require different kinds of skills.2 In this brief, we report on a 2017 survey that asked North Country residents about their perceptions, hopes, and concerns regarding this region. Many of the same questions had been asked on earlier surveys in 2007 and 2010, providing a unique comparative perspective on what has changed or stayed much the same.

This report examines the changing demographics of rural America and shows that the makeup of rural America is changing as certain regions grow with the migration of retirees and baby boomers into amenity-rich areas. At the same time, other places face economic uncertainty as younger residents continue to leave in search of more opportunities. Racial and ethnic diversity, meanwhile, continues to increase.

New Census Bureau data released on March 22, 2018, demonstrate the continuing influence of domestic migration on U.S. demographic trends. Migration patterns are reverting to those common before the recession. Suburban counties of large metropolitan areas, smaller metropolitan areas, and rural counties proximate to metropolitan areas all gained more domestic migrants in the last year. In contrast, domestic migration losses grew in the core counties of metropolitan areas of 1 million or more and remained substantial in rural counties that are not adjacent to an urban area.

New Hampshire’s demographic future depends heavily on migration. The state’s population continued to grow in 2021 and 2022 because a migration gain of 18,300 was enough to offset the excess of deaths over births.

America is growing more racially and ethnically diverse,1 yet some parts of the country are far more diverse than others. Migration—the flow of people from one place to another2—influences local diversity by continually redistributing the population3 and altering the racial mix in both the sending and receiving communities. Migration can serve an integrating function when people from different races move into the same area, but it can also reinforce existing racial boundaries and diminish local diversity when people from different racial groups sort themselves into homogeneous communities. Using new data and techniques, we find that net migration between counties increased racial diversity in each of the last two decades. However, migration’s influence on diversity was far from uniform: it varied by race, age group, and region of the country, sometimes starkly. Overall, net migration of the population under age 40 increased diversity, while net migration of people over age 60 diminished diversity (see Figure 1 and Box 1).4

In this fact sheet, author Kenneth Johnson reports that New Hampshire’s population reached 1,377,529 on April 1, 2020, an increase of 61,000 residents (4.6 percent) since April 1, 2010 according to new 2020 Census data.

In this brief, author Kenneth Johnson reports that New Hampshire gained 40,000 residents (a 3 percent increase) between 2010 and 2018, and the population reached 1,356,458 on July 1, 2018, according to the Census Bureau.

Between July 2008 and July 2009, more people left New Hampshire than moved to it, reversing a trend of domestic migration that had fueled the state's population growth over the past decade, according to U.S. Census Bureau data in released March 2010. This fact sheet summarizes the data.
