Population and Housing Estimates
The Census Bureau makes intercensal city population estimates every July that are released the following year. A summary of the Census Bureau estimates of the city's population since 2000 are available in this graph.City population and housing estimates are based on the 2010 Census population and housing counts with annual revisions based on the city's estimate of net housing construction over each year, rounded to the nearest 50 dwelling units and the nearest 100 people. Because the Census Bureau estimates for the city's population prior to the 2010 Census showed much greater growth than was demonstrated by the 2010 count, the method used by the Census Bureau may have a bias toward overestimating the change in the city's population from year to year. In an effort to minimize this potential bias, the estimates below are based on the assumption that the city's household size has remained constant since 2010 at approximately 2.03 persons per household. Household size has remained below 2.07 persons per household since 1980, was 2.04 in 1990 and 2000. It fell to 2.03 in 2010, in spite of the substantial growth in the number of children in the population and the number of school students between 2000 and 2010. The city has one of the lowest household sizes and highest percentage of single-person households in the U.S. compared to other places of comparable size.
If other information including statistically significant trends in annual American Community Survey data indicate that the household size, vacancy rate, or other characteristics of the city's population and housing are changing in a way that would indicate a higher or lower population estimate is justified, these estimates may be changed.
Population Estimates from 2010 to 2015
Information on population characteristics in the city comes primarily from the U.S. Census Bureau. The decennial census provides very detailed information every 10 years on just a few characteristics of the population based on the attempt to count everyone. Data is available on age, sex, race and ethnicity, household relationships, and whether households own or rent their housing unit. Much of this data is available to the census block level, usually equivalent to a city block. The Census Bureau also conducts a continuing survey of households called The American Community Survey. This continuous survey reaches about 1% or more of all households each year and is tabulated and released yearly. This survey includes many more questions than the decennial census, including questions about income, employment, health insurance, disability, commuting patterns, and location of previous residence. Additional information can be found in the Alexandria 2010 Census Data Profile , which was prepared by City staff and is based on the 2010 Census and the American Community Survey 2006-2010 5-year average data. This report includes data on income, education, housing tenancy, ancestry, commuting, disability, foreign-born population, geographic mobility, and many other characteristics that help define who today's Alexandrians are.
