What does this measure?

Household size measures the average number of people residing in a single housing unit, reflecting citizens’ chosen living arrangements. While family size is certainly a main determinant of household size, this number also provides insight into the financial self-sufficiency of Wake County’s citizens. An uptick in household size may indicate that residents are seeking roommates or moving back in with family during financially hard times, while decreasing household size may indicate that citizens choosing to live independently or with fewer roommates as their finances stabilize. The health and sufficiency of the housing market also affects household size. If there are not enough housing units to accommodate a growing population, we may observe a rise in household size. This statistic impacts population density, which in turn affects how planners shape land usage. School systems, residential and commercial developers, and transportation planners rely on this information when designing their services, programs, and products.

Data Considerations

The Census Bureau's one-year or five-year estimates are referenced based on jurisdiction size. One-year estimates, used for higher-populated areas and considered more current, are used for county, state, and national data. Five-year estimates, considered more accurate, are used for municipal data. More can be read about these estimates here: http://www.census.gov/acs/www/guidance_for_data_users/estimates/
