What does this measure?

Median age measures the relative age of a population by dividing the area's population age distribution into two equal parts: the halves of the population younger and older than the median value. For instance, a median age of 55 means that half of the represented population is over 55, reflecting the prevalence of more middle age and senior adults in an area. Shifts in a population’s age can be attributed to the net impact of changes in life expectancy, declining or increasing birth rates, and migration to and from an area. Many services, from schools to libraries to health and human services, are impacted by the age of the population they serve. Trends in a population’s aging can help business owners and service providers plan for meeting the evolving needs of the community.

How is Wake County performing?

Since 1990 Wake County’s median age has increased significantly, from 31.5 in 1990 to 35.3 in 2013; however, the median age remains consistently lower than the national (37.6) and state (38.1) median age.

Did you know?

Wake County’s population is predicted to reach a median age of 40 by 2030.

Data Considerations

Depending on the size of the jurisdiction, the Census Bureau's one-year or five-year estimates were referenced to determine each jurisdiction's median age. One-year estimates, used for higher-populated areas and, therefore, used for county, state and national data, are considered more current, while five-year estimates are considered more accurate and are used for municipal data. More can be read about these estimates here: http://www.census.gov/acs/www/guidance_for_data_users/estimates/
