LOCATION
The Town of Centreville is centrally located within Maryland’s upper eastern shore
region, 55 miles south of Wilmington, Delaware and 35 east of Baltimore, Maryland
along US Route 301. The region, composed of five mostly rural counties, is home
to 243,245 people (4% of the State) and 123,400 jobs1. Centreville is the county
seat of Queen Ann’s County.

POPULATION AND HOUSEHOLDS
Decade by decade, between 1960 and 2000, Centreville’s population remained
within a narrow band changing only by plus 107 residents as shown below. But
between 2000 and 2010 the population surged; growing at an unprecedent
average annual rate of 8.1%, adding 2,315 residents and more than doubling in
just 10 years2. The current 2020 population is estimated to be 4,815.
Households, which are occupied housing units, increased rapidly too between
2000 and 2010, as would be expected. During the decade, 761 households were
added to the Town bringing the total to 1,568. Households are the “demand units”
for most municipal facilites and services. For example, the number of households
is multiplied by the average water demand to estimate demand for municipal
water. In the next chapter (Municipal Growth) as we look to what future conditions
may bring, we will prepare projections using the number of households.
For decades the Town’s share of Queen Anne’s County’s population and
households fell, from a high of 12.4 percent in 1950 to a low of 4.9 percent by 2000
2 By comparison, over the full 60 years since 1960, the Town has grown at an average annual rate of
1.6 percent.

as shown in the chart below. This was the primarily the result of the County build-
out of Kent Island combined with essentially no growth in Town (or in any of the
County’s municipalities). But by 2010, the Town’s share of the County population
had been restored to its 1960 level before dropping recently to about 10.5 percent.
As of 2018, the latest year data are available, the population of all the towns in the
County, made up only 14.2 percent of the County’s population3.

This is in stark contrast to the other counties in the Upper Eastern Shore region: 29% of Cecil
County’s 2018 population is municipal; 36.3% in Caroline County; 40.2 % in Kent County, and 52.0% in
Talbot County, per MD Department of Planning , State Data Center and Source U.S. Census Bureau,

estimated now to comprise only 20 percent
of the Town’s population.
The Town’s recent very slow pace of household formation may account for this
change as younger families have aged without the offsetting effects of new
households with children. Indeed, 2018 estimates suggest there are 260 fewer
children now than in 2010. The new 2020 Census will provide a more reliable data
set based on direct survey methods, but it is clear the Town’s population is not
becoming more youthful like it had been in the previous decade.

HOUSEHOLD STRUCTURE AND FAMILIES
Like population, the number of households and age, the makeup of households is
an important indication of community character. Data on household structure are
available only from the decennial census, so we note here that the data below are
10 years old.
Composition of Housholds: 2010
# with % of Total
Type of Household # Children Households
Family Households
Married Couple Families 872 413 55.6%
Male Householder, no wife 52 36 3.3%
Female Householder, no husband 178 104 11.4%
Subtotal 1102 553 70.3%
Non-family Households
Householder Unrelated to Occupants 72 4.6%
Householder Living Alone 394 25.1%
Subtotal 466 29.7%
Total Households 1568 100.0%
As shown above in 2010, 1,102 households, or about 70% of all households, were
families--that is, the occupants were related to the householder by birth, marriage
or adoption. About 30% then were non-families, unrelated people living together
or one-person households. By comparison, in 2000, there were 497 family
households, making up 61.2% of the total.
Householders living alone (one-person households) made up nearly 25% (or one
in four) of all households in 2010. By comparison in 2000 there were 265 one-
person households, making up 32.8% of all households.
In Queen Anne’s County (not shown in the table above) family households made
up 73.9% of households and one-person households make up 20.6%.

Other relevant findings from the 2010 Census about Centreville’s households:
• 38% of households had children.
• 30% of households had a person over 65 years of age.
• Average family size was 3.1 persons per family.
• Average household size was 2.6 persons per household.
• Owner-occupied housing units made up 69% of all units with an average
household size of 2.71.
• Renter occupied units made up 23.6% of all units with an average
household size of 2.26.
• Vacant units made up 7.4% of all units.
ECONOMIC CHARACTER AND INDICATORS
LABOR FORCE
The U.S. Census, American Community Survey (ACS) provides current information
on the economic character of Centreville5. The data presented here reflects the
ACS’s aggregation of the years 2013 through 2017.
Of the Town’s population that is 16-years of age and older, 70.8% or 2,570 people
are in the labor force, meaning they are employed or temporarily unemployed.

5 The U.S. Census, American Community Survey (ACS) is an ongoing accounting of certain
demographic and economic data. Because the data are arrived at through statistical methods rather
than just direct counts, the Census publishes a percent margin of error for almost every data point.
Obviously, where sample sizes are smaller, such as at the town-level, the probability of error is
increased. The data used here all have margins of error less than 5% (except where noted or for
household income data, where we’ve included the margin of error in dollar amounts). Comparative
conclusions made here are made only after considering the margins of error associated with the data
points being compared. Data with margins of error greater than 5% are not presented used. The
advantage of using the ACS is that the data are more current, and the methods used span multiple
years of study which can smooth out year to year deviations.
