Race and Ethnic Characteristics -- Loudoun County
2000 2006 Change 2000-2006
Beginning in 2000, the U.S. Census Bureau's methodology for reporting racial profiles allowed the option of selecting more than one race. From 2000 to 2006,
the white population has had the highest amount of growth, and the Asian population has had the highest rate of growth. Other population groups with over 100
percent growth rates include those of two or more races and Hispanics. Note that Hispanic is an ethnicity, and therefore, can be of any race. This race and
ethnicity information is often used in writing grants, advertising, and marketing.

Comparative Demographic Overview
With nearly 5.3 million residents in 2006, the Washington, D.C. metropolitan statistical area represented a sizable and diverse market. The
disproportionately large working-age population and the high income in the metropolitan area supports a dynamic and prosperous economy. In 2006,
Loudoun County ranked second in the United States for median household income. Loudoun's growing Hispanic population, now at 9.7 percent of the
population, represents a lower share of the population than in the metropolitan area but higher than in the Commonwealth of Virginia.

• Per capita income is derived by dividing the total personal income by the total
population, where personal income is the sum of wages and salaries, other labor income,
proprietors' income, rental income of persons, dividend income, personal interest income,
and transfer payments less personal contributions for social insurance.
• Median household income is a middle figure, it divides households into two groups, with
half of all households earning more than the median income and half of all households
earning less.
Because children do not earn income, jurisdictions with higher concentrations of children
will have lower per capita incomes. Loudoun County's population of residents 19 years of
age and younger is over 30 percent, causing Loudoun's per capita income to be lower than
jurisdictions where the population of children is lower.

• Adjusted gross income (AGI) is gathered from income tax returns. AGI is income from
taxable sources (wages and salaries, interest, dividends, and rents and royalties) minus
allowable adjustments, but not including standards and itemized deductions.
Income trends reflect the standard of living that people can afford and the extent to which
living standards vary from person to person. Income statistics are useful in determining
the volume and nature of the goods and services that a population is likely to consume.
The distribution of income within (and between) jurisdictions provides a way to describe the
diversity of the population within the area and across the region as a whole.

royalties) minus allowable adjustments, but not including standards and itemized deductions. Although 2007 figures are not yet available, AGI data are useful
because they represent actual figures rather than survey estimates. Among counties in Virginia, Loudoun had the highest married couple median in 2005, and
ranked second behind Falls Church City among all jurisdictions in Virginia.

Loudoun County benefits from being part of the Washington, D.C. metropolitan area, one
of the most stable employment markets in the nation. With a diverse employment base
that includes many high-wage jobs, the county's residents find many options both within the

Civilian Labor Force -- Northern Virginia
Jurisdictions. . . . . . . . . . . . . . . . . . . . . . . . . .
The labor force is a significant indicator of the economic and social condition of a
community. It defines the supply and demand for employment, and the strength of the
businesses that support that demand. From this information, conclusions can be drawn
about the availability of jobs, the social climate of the area, and the standards of living.
In analyzing the status of a community’s labor force, the following definitions may be
helpful:
• Civilian labor force includes all county residents, 16 and older, who are either working or
looking for work.
• Unemployment number refers to people who had no employment, but were actively
seeking work.
• Unemployment rate is equal to unemployment divided by labor force.

Employment Trends and Forecasts. . . . . . . .
The employment, establishment, and wage information provided here is compiled from the
Quarterly Census of Employment and Wages (QCEW), formally known as ES202. QCEW
is a Federal/State cooperative program that collects and compiles employment and wage
data for workers covered by State unemployment insurance (UI) laws, and Federal civilian
workers covered by Unemployment Compensation for Federal Employees. This data
excludes proprietors, the self-employed, unpaid family members, and certain farm and
domestic workers. The following are additional definitions that may be helpful when
analyzing this data: Trends in Employment by NAICS. . . . . . . . . .
• At-place employment is the number of workers covered by state unemployment
insurance at the cited establishment in Loudoun County.
• An establishment is an economic unit such as a farm, factory, store, or mine that
produces goods or provides services. It is usually at a single physical location and engaged
in one predominant type of economic activity. A business may have more than one
establishment.
In Northern Virginia, Loudoun County ranks third in employment, and is forecasted to add the
second-highest number of jobs of all Northern Virginia counties for each of the decades
between 2000 and 2030.

• Wages consist of earnings before payroll deductions, including production bonuses,
incentive earnings, commissions and cost-of-living adjustment.
Loudoun County has a diverse employment base. Three industry sectors have a 10
percent or greater share of employment: Construction, Retail Trade, and Services. This
diversity has allowed the county to maintain stability when certain industries experience a
slow down, or when the overall economy dips. Transportation and technology-related
businesses, including AOL, United Airlines, and Orbital Sciences Corporation comprise a
significant share of Loudoun's employment.

During the downturn in the national economy from 2000 through 2002, the county's job growth slowed; however, the county never had an overall net loss of jobs.
The diversity of employment in Loudoun has allowed the county to maintain stability when certain industries, or the economy in general, have experienced a
slow down. The mix of employment has remained relatively constant over the past 10 years; however, the Information sector grew significantly in its share, from
2 percent to over 6 percent. Also, while the Transportation & Warehousing sector lost some of its share, decreasing from over 13 percent in 1997 to 7 percent
in 2007, it increased in absolute number during the same time period.

a new accounting and categorization system, only the first and second quarters of 2005 are reported.

Section F - Residential Development
The high quality of life available in Loudoun County makes it a desirable place to live. The
many amenities, prosperous businesses, planned communities, and access to the
Washington, D.C. metropolitan area have all contributed to population growth, and thus,
the residential development in the county. From 1997 through 2007, over 55,000
residential building permits were issued in Loudoun.
Some of the local data presented in this section are presented by planning subarea.
Loudoun originally defined ten geographical regions to identify service delivery areas and
as a guide to the placement of new capital facilities. These subareas are used to forecast
long range trends and needs, and more generally for subcounty analysis. A map showing
the location of these planning subareas is provided in Section I.
