Resource Abstract:
- description: The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic
and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic
Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps
between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined
to cover the entire nation. The primary legal divisions of most States are termed counties. In Louisiana, these divisions
are known as parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and boroughs,
and municipalities, and for the unorganized area, census areas. The latter are delineated cooperatively for statistical purposes
by the State of Alaska and the Census Bureau. In four States (Maryland, Missouri, Nevada, and Virginia), there are one or
more incorporated places that are independent of any county organization and thus constitute primary divisions of their States.
These incorporated places are known as independent cities and are treated as equivalent entities for purposes of data presentation.
The District of Columbia and Guam have no primary divisions, and each area is considered an equivalent entity for purposes
of data presentation. The Census Bureau treats the following entities as equivalents of counties for purposes of data presentation:
Municipios in Puerto Rico, Districts and Islands in American Samoa, Municipalities in the Commonwealth of the Northern Mariana
Islands, and Islands in the U.S. Virgin Islands. The entire area of the United States, Puerto Rico, and the Island Areas is
covered by counties or equivalent entities. The 2010 Census boundaries for counties and equivalent entities are as of January
1, 2010, primarily as reported through the Census Bureau's Boundary and Annexation Survey (BAS).<br /><br />
This table contains data on race, age, sex, and marital status from the American Community Survey 2006-2010 database for counties.
The American Community Survey (ACS) is a household survey conducted by the U.S. Census Bureau that currently has an annual
sample size of about 3.5 million addresses. ACS estimates provides communities with the current information they need to plan
investments and services. Information from the survey generates estimates that help determine how more than $400 billion in
federal and state funds are distributed annually. Each year the survey produces data that cover the periods of 1-year, 3-year,
and 5-year estimates for geographic areas in the United States and Puerto Rico, ranging from neighborhoods to Congressional
districts to the entire nation. This table also has a companion table (Same table name with MOE Suffix) with the margin of
error (MOE) values for each estimated element. MOE is expressed as a measure value for each estimated element. So a value
of 25 and an MOE of 5 means 25 +/- 5 (or statistical certainty between 20 and 30). There are also special cases of MOE. An
MOE of -1 means the associated estimates do not have a measured error. An MOE of 0 means that error calculation is not appropriate
for the associated value. An MOE of 109 is set whenever an estimate value is 0. The MOEs of aggregated elements and percentages
must be calculated. This process means using standard error calculations as described in "American Community Survey Multiyear
Accuracy of the Data (3-year 2008-2010 and 5-year 2006-2010)". Also, following Census guidelines, aggregated MOEs do
not use more than 1 0-element MOE (109) to prevent over estimation of the error. Due to the complexity of the calculations,
some percentage MOEs cannot be calculated (these are set to null in the summary-level MOE tables).<br /><br />
The name for table 'ACS10POPCNTYMOE' was added as a prefix to all field names imported from that table. Be sure
to turn off 'Show Field Aliases' to see complete field names in the Attribute Table of this feature layer. This
can be done in the 'Table Options' drop-down menu in the Attribute Table or with key sequence '[CTRL]+[SHIFT]+N'.
Due to database restrictions, the prefix may have been abbreviated if the field name exceded the maximum allowed characters.;
