The American Community Survey (ACS) is a nationwide survey conducted by the U.S. Census Bureau designed to provide communities a fresh look at how they are changing. The ACS collects information such as age, race, income, commute time to work, home value, veteran status, and other important data.

The American Community Survey(ACS) is an ongoing survey that asks questions about demographic, social, economic, and housing characteristics of the population. This data is an estimate based on a small sample and can have a large margin of error. Please note that the margin of error is not shown on this map.

The data profiles accessible through this page provide demographic information (race, ethnicity, and total housing units) as well as social characteristics (relationships, languages spoken at home, and marital, educational, and disability status); economics (income, employment, occupation, and commute to work); and housing characteristics (occupancy, tenure, year built, and housing value and cost). This information is based on a sample collected over the most recent five years and is not based on the 2010 decennial Census.

Some data values represent unique situations where either:

a) the information to be conveyed is an explanation for the absence of data, represented by a symbol in the data display, such as "(X)", or
b) the information to be conveyed is an open-ended distribution, such as 115 or greater, represented by 115+.

Following are the special data values (and their meaning) for case (a), which can appear in any 2005-2009 ACS table or map product:
-999999999 = N Indicates that an estimate or its margin of error cannot be provided because the number of sample cases is too small for the given geographic area.

-888888888 = (X) Indicates that the estimate is not applicable or not available.

-777777777 = (Z) Estimate is not available for an undefined reason.

-666666666 = - Indicates that no sample observations were available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls in the lowest interval or upper interval of an open-ended distribution.
