In this fact sheet, author Ken Johnson reports on new Census Bureau data released on March 26, 2015. The data provide further evidence that the recession’s influence on domestic migration is diminishing. Migration patterns are reverting to those commonly seen before the recession. Suburban counties of large metropolitan areas are receiving more domestic migrants, while large metropolitan core counties are seeing more domestic migration losses. Domestic migration losses also continue in rural areas. There is no evidence in these new Census data of any recovery in fertility. Births remain near 15-year lows, and there were a record number of deaths last year.

In this brief, Carsey Senior Demographer Kenneth Johnson reports that COVID’s impact is reflected in the sharp rise in U.S. deaths, reaching 3,434,000 between July 2020 and July 2021. This is a record high and 20 percent more than two years ago before the COVID pandemic.

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 brief, Senior Demographer Kenneth Johnson reports that, according to recent Census Bureau estimates, the U.S. population has grown at the slowest rate in history in the past two years due to the impact of Covid.

The U.S. population grew by a modest 7.4 percent during the past decade to 331.4 million in April 2020. There was a significant increase in racial diversity over the course of the decade, both in the population as a whole, and children in particular.

This brief summarizes current population redistribution trends in the Granite State and shows how fertility, mortality, and migration contributed to these trends. According to the 2010 census, New Hampshire gained 80,700 residents (a 6.5 percent increase) between 2000 and 2010, mostly during the earlier years of the decade.

In this data snapshot, authors Kenneth Johnson, Andrew Smith, and Dante Scala discuss changes in the New Hampshire voting population since 2016 and its implications for the 2022 mid-term election.

In this data snapshot, author Kenneth Johnson reports that the population of New Hampshire grew by 5,500 to 1,366,000 between July of 2019 and July of 2020, according to new Census Bureau estimates. ​This was the largest percentage population gain in New England. ​

In this data snapshot, authors Kenneth Johnson, Dante Scala, and Andrew Smith discuss factors that could influence the outcome of New Hampshire's 2020 Primary.
