Nonmetro areas in some parts of the country have experienced population loss for decades. However, the 2010-12 period marks the first years with estimated population loss for nonmetro America as a whole.
- The estimated population loss of just under 44,000 people represents a quite small -0.09 percentage loss for nonmetro areas as a whole.
- The number of nonmetro counties losing population during 2010-12 reached an historic high of 1,261. Taken together, these counties declined in population by 302,000 people, while the 715 nonmetro counties that gained population added 258,000 people.
Nonmetro areas do "lose" population every 10 years when nonmetro counties that have been growing rapidly enough become reclassified as metro. In the latest update announced by the Office of Management and Budget in late February 2013, 113 nonmetro counties (with just under 5.9 million people) switched to metro status while 36 counties (with just over 1 million people) no longer qualified as metro, resulting in a net nonmetro population "loss" of 4.8 million from reclassification. The nonmetro population loss described here is independent of reclassification, having occurred in a constant set of nonmetro counties, those defined as of 2013.

County population change includes two major components: natural change (births minus deaths) and net migration (in-migrants minus out-migrants).
- Nonmetro population loss of -44,000 during 2010-12 reflects natural increase of 135,000 offset by net out-migration of -179,000.

- While natural change has gradually trended downward over time, net migration rates tend to fluctuate in response to economic conditions.
Historically, nonmetro population grew because high natural increase always offset any net migration loss nonmetro areas experienced.
- Rural out-migration peaked in the 1950s and 1960s (not shown on graph), but was offset by high "baby boom" birth rates.
- Net out-migration from nonmetro areas was more severe during the 1980s compared with 2010-12, but overall population change remained positive during the 1980s because natural increase contributed roughly 0.5 percent growth (compared with 0.2 percent today).
- Falling birth rates and an aging population have steadily dampened the contribution of natural change to nonmetro population growth.
- Nonmetro net migration rates peaked during the 'rural rebound' in the mid-1990s and again in 2004-06, just prior to the recent housing mortgage crisis and economic recession. Net migration remained positive for much of the past two decades, increasing nonmetro population every year but one from 1990 to 2008, but has since contributed to population loss.
Lowering rates of natural change contributed to expanded population decline in nonmetro areas and resulted in roughly 300 counties experiencing natural decrease for the first time during 2010-12. The map shows natural change for all counties, metro and nonmetro. Urbanized areas (shown in dark gray) are at the center of metro areas and nonmetro counties are those that are some distance removed, depending on the size of the metro area.

- Areas that recently began experiencing natural decrease are found in the Northeast, South, and especially around the margins of Appalachia, expanding a large region of natural decrease extending from Pennsylvania through northern Alabama.
- Counties end up as natural decrease counties as a result of two separate demographic processes operating over several decades: retiree attraction and long-term out-migration of young adults (who take their future children with them, so to speak).
- Typically, these trends occur in different regions of the country; the former in Florida, Arizona, and other Sunbelt locations; the latter in persistent out-migration areas such as in the Great Plains and Corn Belt. However, both trends are contributing to the emergence of natural decrease counties in many nonmetro regions, such as in Virginia, Kentucky, North Carolina, and Tennessee.
It is important to state that new population estimates are sometimes revised, either upward or downward. Also, the period of nonmetro population loss may be short-lived depending on the course of the economic recovery. Even if temporary, this small but historic shift to overall population loss highlights a growing demographic challenge facing many regions across rural and small-town America, as population growth from natural increase is no longer large enough to counter cyclical net migration losses.
