2010-2014 County Population Change and Components of Change

Two fundamental processes underpin population growth—or decline. The first, natural increase (or natural decrease) captures the balance of births and deaths in an area and reflects the underlying age structure of the population. Relatively young populations tend to have more births than deaths, or natural increase. Relatively older populations, on the other hand, tend to experience natural decrease, more deaths than births. The second, net migration, reflects the appeal of an area relative to other…

NC in Focus: Share of Counties with Population Loss, 2010-2014

Nationwide, the majority of counties have lost population since 2010, according to recent estimates from the U.S. Census Bureau. State by state, the share of counties that have lost population varies substantially (as does the number of counties per state!). In 27 states, half or more of the counties lost population between 2010 and 2014. The highest proportion of loss—80%--was seen in Illinois and Rhode Island. North Carolina was one of the 23 states where…

Nationwide, majority of counties have lost population since 2010

When the Census Bureau releases its annual population estimates, we often focus on counties and metropolitan areas with the largest numerical growth or the fastest growth rates. Yet the majority of counties are not growing. Nationwide, 1,660 of 3,142 counties, or 53%, lost population between April 1, 2010 and July 1, 2014. In North Carolina, 49 of the state’s 100 counties lost population. This is a marked increase over a decade prior. Between 2000 and…

What you need to know about the 2014 population estimates

North Carolina’s population has grown by more than 408,000 new residents since the 2010 Census. Of these, 95,000 were added between July 1, 2013 and July 1, 2014. New county population estimates from the U.S. Census Bureau highlight how counties and metropolitan areas changed over this same time period. In many ways, the 2014 estimates are a continuation of the population trends we saw in the 2013 estimates: metropolitan regions are driving the state’s overall…

Relationship Status by Census Tract

“Some places attract young singles, whereas others attract married couples and families,” writes Nathan Yau on his data visualization blog, Flowing Data. This is something that I often discuss when I present to audiences around the state: places have age-specific migration profiles that reflect both the reasons why people are moving to a place, and the potential demands that they will have when they get there. Some places, like Mecklenburg County, have net migration profiles…

NC in Focus: Ever Married by Age

Nationally, 2 in 3 individuals 15 and older have ever been married according to the 2013 American Community Survey. In North Carolina, this proportion is slightly higher: 68.2%. The vast majority (71%) of ever married North Carolinians are still married. Another sixteen percent are divorced, four percent are currently separated, and nine percent are widowed. Examining trends by age shows similar trends in North Carolina and the nation. The share of individuals ever married stays…

NC Legislative Districts and Deviation from Ideal Population Size, 2013

May 21, 2015 update: The original post defined compliance for U.S. Congressional Districts as within +/-1%. Although the courts require adherence to equal population as much as possible, the maximum potentially accepted deviation cited elsewhere is a total spread of 1%, meaning +/- 0.5%. Following the decennial Census, political districts, such as U.S. Congressional districts and state legislative districts, are redrawn in a process called redistricting. The goal is to make each district as close…

NC in Focus: Professional Services Employment, 1850-2010

In 1870, fewer than 3% of U.S. workers were employed in professional services, a category that includes educational, engineering, legal, and medical services (including individuals working in hospitals). Just 1.5% of North Carolina workers were employed in professional service industries in 1870. Nationally, employment in professional services represented less than 5% of all employees until 1930. After that, the share of employees in professional services grew steadily through 1960, and grew even more rapidly between…

What will your city be like in 15 years?

We know that Raleigh and Charlotte are among the fastest growing urban areas in the nation, while many rural areas of the state are facing population losses and stagnation. But if we know anything about the future with certainty, it’s that the future is inherently uncertain! How likely are these patterns? A new interactive tool from the Urban Institute uses historical trends and census data to map population projections for every state and metro area…

NC in Focus: NC Born by Age, 1950-2013

Forty-two percent of North Carolina residents were born in another state or country. In 1950, this proportion was only 15%. The share of North Carolina residents born in state declines steadily with age until prime working-ages, and then begins rising again. Between ages 27 and 50, more than half of North Carolina residents were born in another state or country. North Carolina’s trends in the proportion of native-born residents by age look similar to those of…
